        Note: This method should be used for on-premise deployments only.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

      • adminAddHost

        public AdminAddHostResponse adminAddHost​(String hostAddress,
                                         Map<String,​String> options)
                                  throws GPUdbException
        Adds a host to an existing cluster.

        Note: This method should be used for on-premise deployments only.

        Parameters:
        hostAddress - IP address of the host that will be added to the cluster. This host must have installed the same version of Kinetica as the cluster to which it is being added.
        options - Optional parameters.
        • DRY_RUN: If set to TRUE, only validation checks will be performed. No host is added. Supported values: The default value is FALSE.
        • ACCEPTS_FAILOVER: If set to TRUE, the host will accept processes (ranks, graph server, etc.) in the event of a failover on another node in the cluster. Supported values: The default value is FALSE.
        • PUBLIC_ADDRESS: The publicly-accessible IP address for the host being added, typically specified for clients using multi-head operations. This setting is required if any other host(s) in the cluster specify a public address.
        • HOST_MANAGER_PUBLIC_URL: The publicly-accessible full path URL to the host manager on the host being added, e.g., 'http://172.123.45.67:9300'. The default host manager port can be found in the list of ports used by Kinetica.
        • RAM_LIMIT: The desired RAM limit for the host being added, i.e. the sum of RAM usage for all processes on the host will not be able to exceed this value. Supported units: K (thousand), KB (kilobytes), M (million), MB (megabytes), G (billion), GB (gigabytes); if no unit is provided, the value is assumed to be in bytes. For example, if RAM_LIMIT is set to 10M, the resulting RAM limit is 10 million bytes. Set RAM_LIMIT to -1 to have no RAM limit.
        • GPUS: Comma-delimited list of GPU indices (starting at 1) that are eligible for running worker processes. If left blank, all GPUs on the host being added will be eligible.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

      • adminAddRanks

        public AdminAddRanksResponse adminAddRanks​(AdminAddRanksRequest request)
                                    throws GPUdbException
        Add one or more ranks to an existing Kinetica cluster. The new ranks will not contain any data initially (other than replicated tables) and will not be assigned any shards. To rebalance data and shards across the cluster, use adminRebalance.

        The database must be offline for this operation, see adminOffline

        For example, if attempting to add three new ranks (two ranks on host 172.123.45.67 and one rank on host 172.123.45.68) to a Kinetica cluster with additional configuration parameters:

        * hosts would be an array including 172.123.45.67 in the first two indices (signifying two ranks being added to host 172.123.45.67) and 172.123.45.68 in the last index (signifying one rank being added to host 172.123.45.67)

        * configParams would be an array of maps, with each map corresponding to the ranks being added in hosts. The key of each map would be the configuration parameter name and the value would be the parameter's value, e.g. '{"rank.gpu":"1"}'

        This endpoint's processing includes copying all replicated table data to the new rank(s) and therefore could take a long time. The API call may time out if run directly. It is recommended to run this endpoint asynchronously via createJob.

        Note: This method should be used for on-premise deployments only.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

      • adminAddRanks

                                           Map<String,​String> options)
                                    throws GPUdbException

        * configParams would be an array of maps, with each map corresponding to the ranks being added in hosts. The key of each map would be the configuration parameter name and the value would be the parameter's value, e.g. '{"rank.gpu":"1"}'

        This endpoint's processing includes copying all replicated table data to the new rank(s) and therefore could take a long time. The API call may time out if run directly. It is recommended to run this endpoint asynchronously via createJob.

        Note: This method should be used for on-premise deployments only.

        Parameters:
        hosts - Array of host IP addresses (matching a hostN.address from the gpudb.conf file), or host identifiers (e.g. 'host0' from the gpudb.conf file), on which to add ranks to the cluster. The hosts must already be in the cluster. If needed beforehand, to add a new host to the cluster use adminAddHost. Include the same entry as many times as there are ranks to add to the cluster, e.g., if two ranks on host 172.123.45.67 should be added, hosts could look like '["172.123.45.67", "172.123.45.67"]'. All ranks will be added simultaneously, i.e. they're not added in the order of this array. Each entry in this array corresponds to the entry at the same index in the configParams.
        configParams - Array of maps containing configuration parameters to apply to the new ranks found in hosts. For example, '{"rank.gpu":"2", "tier.ram.rank.limit":"10000000000"}'. Currently, the available parameters are rank-specific parameters in the Network, Hardware, Text Search, and RAM Tiered Storage sections in the gpudb.conf file, with the key exception of the 'rankN.host' settings in the Network section that will be determined by hosts instead. Though many of these configuration parameters typically are affixed with 'rankN' in the gpudb.conf file (where N is the rank number), the 'N' should be omitted in configParams as the new rank number(s) are not allocated until the ranks have been added to the cluster. Each entry in this array corresponds to the entry at the same index in the hosts. This array must either be completely empty or have the same number of elements as the hosts. An empty configParams array will result in the new ranks being set with default parameters.
        options - Optional parameters.
        • DRY_RUN: If TRUE, only validation checks will be performed. No ranks are added. Supported values: The default value is FALSE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

      • adminRebalance

        public AdminRebalanceResponse adminRebalance​(Map<String,​String> options)
                                      throws GPUdbException
        Rebalance the data in the cluster so that all nodes contain an equal number of records approximately and/or rebalance the shards to be equally distributed (as much as possible) across all the ranks.

        The database must be offline for this operation, see adminOffline

        * If adminRebalance is invoked after a change is made to the cluster, e.g., a host was added or removed, sharded data will be evenly redistributed across the cluster by number of shards per rank while unsharded data will be redistributed across the cluster by data size per rank

        * If adminRebalance is invoked at some point when unsharded data (a.k.a. randomly-sharded) in the cluster is unevenly distributed over time, sharded data will not move while unsharded data will be redistributed across the cluster by data size per rank

        This endpoint's processing time depends on the amount of data in the system, thus the API call may time out if run directly. It is recommended to run this endpoint asynchronously via createJob.

        Parameters:
        options - Optional parameters.
        • REBALANCE_SHARDED_DATA: If TRUE, sharded data will be rebalanced approximately equally across the cluster. Note that for clusters with large amounts of sharded data, this data transfer could be time consuming and result in delayed query responses. Supported values: The default value is TRUE.
        • REBALANCE_UNSHARDED_DATA: If TRUE, unsharded data (a.k.a. randomly-sharded) will be rebalanced approximately equally across the cluster. Note that for clusters with large amounts of unsharded data, this data transfer could be time consuming and result in delayed query responses. Supported values: The default value is TRUE.
        • TABLE_INCLUDES: Comma-separated list of unsharded table names to rebalance. Not applicable to sharded tables because they are always rebalanced. Cannot be used simultaneously with TABLE_EXCLUDES. This parameter is ignored if REBALANCE_UNSHARDED_DATA is FALSE.
        • TABLE_EXCLUDES: Comma-separated list of unsharded table names to not rebalance. Not applicable to sharded tables because they are always rebalanced. Cannot be used simultaneously with TABLE_INCLUDES. This parameter is ignored if REBALANCE_UNSHARDED_DATA is FALSE.
        • AGGRESSIVENESS: Influences how much data is moved at a time during rebalance. A higher AGGRESSIVENESS will complete the rebalance faster. A lower AGGRESSIVENESS will take longer but allow for better interleaving between the rebalance and other queries. Valid values are constants from 1 (lowest) to 10 (highest). The default value is '10'.
        • COMPACT_AFTER_REBALANCE: Perform compaction of deleted records once the rebalance completes to reclaim memory and disk space. Default is TRUE, unless REPAIR_INCORRECTLY_SHARDED_DATA is set to TRUE. Supported values: The default value is TRUE.
        • COMPACT_ONLY: If set to TRUE, ignore rebalance options and attempt to perform compaction of deleted records to reclaim memory and disk space without rebalancing first. Supported values: The default value is FALSE.
        • REPAIR_INCORRECTLY_SHARDED_DATA: Scans for any data sharded incorrectly and re-routes the data to the correct location. Only necessary if adminVerifyDb reports an error in sharding alignment. This can be done as part of a typical rebalance after expanding the cluster or in a standalone fashion when it is believed that data is sharded incorrectly somewhere in the cluster. Compaction will not be performed by default when this is enabled. If this option is set to TRUE, the time necessary to rebalance and the memory used by the rebalance may increase. Supported values: The default value is FALSE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

                                                throws GPUdbException
        Calculates unique combinations (groups) of values for the given columns in a given table or view and computes aggregates on each unique combination. This is somewhat analogous to an SQL-style SELECT...GROUP BY.

        For aggregation details and examples, see Aggregation. For limitations, see Aggregation Limitations.

        Any column(s) can be grouped on, and all column types except unrestricted-length strings may be used for computing applicable aggregates; columns marked as store-only are unable to be used in grouping or aggregation.

        The results can be paged via the offset and limit parameters. For example, to get 10 groups with the largest counts the inputs would be: limit=10, options={"sort_order":"descending", "sort_by":"value"}.

        options can be used to customize behavior of this call e.g. filtering or sorting the results.

        To group by columns 'x' and 'y' and compute the number of objects within each group, use: column_names=['x','y','count(*)'].

        To also compute the sum of 'z' over each group, use: column_names=['x','y','count(*)','sum(z)'].

        Available aggregation functions are: count(*), sum, min, max, avg, mean, stddev, stddev_pop, stddev_samp, var, var_pop, var_samp, arg_min, arg_max and count_distinct.

        Available grouping functions are Rollup, Cube, and Grouping Sets

        This service also provides support for Pivot operations.

        Filtering on aggregates is supported via expressions using aggregation functions supplied to HAVING.

        The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

        If a RESULT_TABLE name is specified in the options, the results are stored in a new table with that name--no results are returned in the response. Both the table name and resulting column names must adhere to standard naming conventions; column/aggregation expressions will need to be aliased. If the source table's shard key is used as the grouping column(s) and all result records are selected (offset is 0 and limit is -9999), the result table will be sharded, in all other cases it will be replicated. Sorting will properly function only if the result table is replicated or if there is only one processing node and should not be relied upon in other cases. Not available when any of the values of columnNames is an unrestricted-length string.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:

        • PIVOT_VALUES: The value list provided will become the column headers in the output. Should be the values from the pivot_column.
        • GROUPING_SETS: Customize the grouping attribute sets to compute the aggregates. These sets can include ROLLUP or CUBE operators. The attribute sets should be enclosed in parentheses and can include composite attributes. All attributes specified in the grouping sets must present in the group-by attributes.
        • ROLLUP: This option is used to specify the multilevel aggregates.
        • CUBE: This option is used to specify the multidimensional aggregates.
        • SHARD_KEY: Comma-separated list of the columns to be sharded on; e.g. 'column1, column2'. The columns specified must be present in columnNames. If any alias is given for any column name, the alias must be used, rather than the original column name. The default value is ''.

The value returned for each bin is the number of records in it, except when a column name is provided as a VALUE_COLUMN. In this latter case the sum of the values corresponding to the VALUE_COLUMN is used as the result instead. The total number of bins requested cannot exceed 10,000.

        NOTE: The Kinetica instance being accessed must be running a CUDA (GPU-based) build to service a request that specifies a VALUE_COLUMN.

        Parameters:

        This endpoint runs the k-means algorithm - a heuristic algorithm that attempts to do k-means clustering. An ideal k-means clustering algorithm selects k points such that the sum of the mean squared distances of each member of the set to the nearest of the k points is minimized. The k-means algorithm however does not necessarily produce such an ideal cluster. It begins with a randomly selected set of k points and then refines the location of the points iteratively and settles to a local minimum. Various parameters and options are provided to control the heuristic search.

        NOTE: The Kinetica instance being accessed must be running a CUDA (GPU-based) build to service this request.

        Parameters:

      • aggregateStatistics

        public AggregateStatisticsResponse aggregateStatistics​(AggregateStatisticsRequest request)
                                                throws GPUdbException
        Calculates the requested statistics of the given column(s) in a given table.

        The available statistics are: COUNT (number of total objects), MEAN, STDV (standard deviation), VARIANCE, SKEW, KURTOSIS, SUM, MIN, MAX, WEIGHTED_AVERAGE, CARDINALITY (unique count), ESTIMATED_CARDINALITY, PERCENTILE, and PERCENTILE_RANK.

        Estimated cardinality is calculated by using the hyperloglog approximation technique.

        Percentiles and percentile ranks are approximate and are calculated using the t-digest algorithm. They must include the desired PERCENTILE/PERCENTILE_RANK. To compute multiple percentiles each value must be specified separately (i.e. 'percentile(75.0),percentile(99.0),percentile_rank(1234.56),percentile_rank(-5)').

        A second, comma-separated value can be added to the PERCENTILE statistic to calculate percentile resolution, e.g., a 50th percentile with 200 resolution would be 'percentile(50,200)'.

        The weighted average statistic requires a weight column to be specified in WEIGHT_COLUMN_NAME. The weighted average is then defined as the sum of the products of columnName times the WEIGHT_COLUMN_NAME values divided by the sum of the WEIGHT_COLUMN_NAME values.

        Additional columns can be used in the calculation of statistics via ADDITIONAL_COLUMN_NAMES. Values in these columns will be included in the overall aggregate calculation--individual aggregates will not be calculated per additional column. For instance, requesting the COUNT and MEAN of columnName x and ADDITIONAL_COLUMN_NAMES y and z, where x holds the numbers 1-10, y holds 11-20, and z holds 21-30, would return the total number of x, y, and z values (30), and the single average value across all x, y, and z values (15.5).

        The response includes a list of key/value pairs of each statistic requested and its corresponding value.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        • STDV: Sample standard deviation (denominator is count-1).
        • VARIANCE: Unbiased sample variance (denominator is count-1).
        • SKEW: Skewness (third standardized moment).
        • KURTOSIS: Kurtosis (fourth standardized moment).
        • SUM: Sum of all values in the column(s).
        • MIN: Minimum value of the column(s).

        Divides the given set into bins and calculates statistics of the values of a value-column in each bin. The bins are based on the values of a given binning-column. The statistics that may be requested are mean, stdv (standard deviation), variance, skew, kurtosis, sum, min, max, first, last and weighted average. In addition to the requested statistics the count of total samples in each bin is returned. This counts vector is just the histogram of the column used to divide the set members into bins. The weighted average statistic requires a weight column to be specified in WEIGHT_COLUMN_NAME. The weighted average is then defined as the sum of the products of the value column times the weight column divided by the sum of the weight column.

        There are two methods for binning the set members. In the first, which can be used for numeric valued binning-columns, a min, max and interval are specified. The number of bins, nbins, is the integer upper bound of (max-min)/interval. Values that fall in the range [min+n*interval,min+(n+1)*interval) are placed in the nth bin where n ranges from 0..nbin-2. The final bin is [min+(nbin-1)*interval,max]. In the second method, BIN_VALUES specifies a list of binning column values. Binning-columns whose value matches the nth member of the BIN_VALUES list are placed in the nth bin. When a list is provided, the binning-column must be of type string or int.

        Returns all the unique values from a particular column (specified by columnName) of a particular table or view (specified by tableName). If columnName is a numeric column, the values will be in data. Otherwise if columnName is a string column, the values will be in jsonEncodedResponse. The results can be paged via offset and limit parameters.

        Columns marked as store-only are unable to be used with this function.

        To get the first 10 unique values sorted in descending order options would be: 

        
     {"limit":"10","sort_order":"descending"}
        The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

        If a RESULT_TABLE name is specified in the options, the results are stored in a new table with that name--no results are returned in the response. Both the table name and resulting column name must adhere to standard naming conventions; any column expression will need to be aliased.

The variable column and value columns in the result table indicate the pivoted column name and values respectively.

        The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

        Parameters:
        tableName - Name of the table on which the operation will be performed. Must be an existing table/view, in [schema_name.]table_name format, using standard name resolution rules.
        columnNames - List of column names or expressions. A wildcard '*' can be used to include all the non-pivoted columns from the source table.
        variableColumnName - Specifies the variable/parameter column name. The default value is ''.
        valueColumnName - Specifies the value column name. The default value is ''.
        pivotedColumns - List of one or more values typically the column names of the input table. All the columns in the source table must have the same data type.
        options - Optional parameters.
        • CREATE_TEMP_TABLE: If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of RESULT_TABLE. If RESULT_TABLE_PERSIST is FALSE (or unspecified), then this is always allowed even if the caller does not have permission to create tables. The generated name is returned in QUALIFIED_RESULT_TABLE_NAME. Supported values: The default value is FALSE.

        • LIMIT: The number of records to keep. The default value is ''.
        • TTL: Sets the TTL of the table specified in RESULT_TABLE.
        • VIEW_ID: view this result table is part of. The default value is ''.
        • CREATE_INDEXES: Comma-separated list of columns on which to create indexes on the table specified in RESULT_TABLE. The columns specified must be present in output column names. If any alias is given for any column name, the alias must be used, rather than the original column name.
        • RESULT_TABLE_FORCE_REPLICATED: Force the result table to be replicated (ignores any sharding). Must be used in combination with the RESULT_TABLE option. Supported values: The default value is FALSE.
        The default value is an empty Map.

        Apply various modifications to a table or view. The available modifications include the following:

        Manage a table's columns--a column can be added, removed, or have its type and properties modified, including whether it is dictionary encoded or not.

        External tables cannot be modified except for their refresh method.

        Create or delete a column, low-cardinality index, chunk skip, geospatial, CAGRA, or HNSW index. This can speed up certain operations when using expressions containing equality or relational operators on indexed columns. This only applies to tables.

        Create or delete a foreign key on a particular column.

        Manage a range-partitioned or a manual list-partitioned table's partitions.

        Set (or reset) the tier strategy of a table or view.

        Refresh and manage the refresh mode of a materialized view or an external table.

        Set the time-to-live (TTL). This can be applied to tables or views.

        Set the global access mode (i.e. locking) for a table. This setting trumps any role-based access controls that may be in place; e.g., a user with write access to a table marked read-only will not be able to insert records into it. The mode can be set to read-only, write-only, read/write, and no access.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.

If set to FALSE, any existing table record with primary key values that match those of a source table record being inserted will remain unchanged, while the source record will be rejected and an error handled as determined by IGNORE_EXISTING_PK. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Upsert new records when primary keys match existing records
          • FALSE: Reject new records when primary keys match existing records
          The default value is FALSE.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting source table records (specified by sourceTableName) into a target table (specified by tableName) with a primary key, only used when not in upsert mode (upsert mode is disabled when UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any source table record being inserted that is rejected for having primary key values that match those of an existing target table record will be ignored with no error generated. If FALSE, the rejection of any source table record for having primary key values matching an existing target table record will result in an error being raised. If the specified table does not have a primary key or if upsert mode is in effect (UPDATE_ON_EXISTING_PK is TRUE), then this option has no effect. Supported values:
          • TRUE: Ignore source table records whose primary key values collide with those of target table records
          • FALSE: Raise an error for any source table record whose primary key values collide with those of a target table record
          The default value is FALSE.
        • PK_CONFLICT_PREDICATE_HIGHER: The record with higher value for the column resolves the primary-key insert conflict. The default value is ''.
        • PK_CONFLICT_PREDICATE_LOWER: The record with lower value for the column resolves the primary-key insert conflict. The default value is ''.
        • TRUNCATE_STRINGS: If set to TRUE, it allows inserting longer strings into smaller charN string columns by truncating the longer strings to fit. Supported values: The default value is FALSE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        The default value is true.
        nodes - Nodes represent fundamental topological units of a graph. Nodes must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS NODE_ID', expressions, e.g., 'ST_MAKEPOINT(column1, column2) AS NODE_WKTPOINT', or constant values, e.g., '{9, 10, 11} AS NODE_ID'. If using constant values in an identifier combination, the number of values specified must match across the combination.
        edges - Edges represent the required fundamental topological unit of a graph that typically connect nodes. Edges must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS EDGE_ID', expressions, e.g., 'SUBSTR(column, 1, 6) AS EDGE_NODE1_NAME', or constant values, e.g., "{'family', 'coworker'} AS EDGE_LABEL". If using constant values in an identifier combination, the number of values specified must match across the combination.
        weights - Weights represent a method of informing the graph solver of the cost of including a given edge in a solution. Weights must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS WEIGHTS_EDGE_ID', expressions, e.g., 'ST_LENGTH(wkt) AS WEIGHTS_VALUESPECIFIED', or constant values, e.g., '{4, 15} AS WEIGHTS_VALUESPECIFIED'. If using constant values in an identifier combination, the number of values specified must match across the combination.
        restrictions - Restrictions represent a method of informing the graph solver which edges and/or nodes should be ignored for the solution. Restrictions must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS RESTRICTIONS_EDGE_ID', expressions, e.g., 'column/2 AS RESTRICTIONS_VALUECOMPARED', or constant values, e.g., '{0, 0, 0, 1} AS RESTRICTIONS_ONOFFCOMPARED'. If using constant values in an identifier combination, the number of values specified must match across the combination.
        options - Optional parameters.
        • MERGE_TOLERANCE: If node geospatial positions are input (e.g., WKTPOINT, X, Y), determines the minimum separation allowed between unique nodes. If nodes are within the tolerance of each other, they will be merged as a single node. The default value is '1.0E-5'.
        • RECREATE: If set to TRUE and the graph (using graphName) already exists, the graph is deleted and recreated. Supported values: The default value is FALSE.
        • SAVE_PERSIST: If set to TRUE, the graph will be saved in the persist directory (see the config reference for more information). If set to FALSE, the graph will be removed when the graph server is shutdown. Supported values: The default value is FALSE.
        • ADD_TABLE_MONITOR: Adds a table monitor to every table used in the creation of the graph; this table monitor will trigger the graph to update dynamically upon inserts to the source table(s).

                                          throws GPUdbException
        Creates a new projection of an existing table. A projection represents a subset of the columns (potentially including derived columns) of a table.

        For projection details and examples, see Projections. For limitations, see Projection Limitations and Cautions.

        Window functions, which can perform operations like moving averages, are available through this endpoint as well as getRecordsByColumn.

        A projection can be created with a different shard key than the source table. By specifying SHARD_KEY, the projection will be sharded according to the specified columns, regardless of how the source table is sharded. The source table can even be unsharded or replicated.

        If tableName is empty, selection is performed against a single-row virtual table. This can be useful in executing temporal (NOW()), identity (USER()), or constant-based functions (GEODIST(-77.11, 38.88, -71.06, 42.36)).

        Parameters:
        tableName - Name of the existing table on which the projection is to be applied, in [schema_name.]table_name format, using standard name resolution rules. An empty table name creates a projection from a single-row virtual table, where columns specified should be constants or constant expressions.
        projectionName - Name of the projection to be created, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria.
        columnNames - List of columns from tableName to be included in the projection. Can include derived columns. Can be specified as aliased via the syntax 'column_name as alias'.
        options - Optional parameters.
        • CREATE_TEMP_TABLE: If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of projectionName. If PERSIST is FALSE (or unspecified), then this is always allowed even if the caller does not have permission to create tables. The generated name is returned in QUALIFIED_PROJECTION_NAME. Supported values: The default value is FALSE.
        • COLLECTION_NAME: [DEPRECATED--please specify the containing schema for the projection as part of projectionName and use createSchema to create the schema if non-existent] Name of a schema for the projection.

        • EXPRESSION: An optional filter expression to be applied to the source table prior to the projection. The default value is ''.
        • IS_REPLICATED: If TRUE then the projection will be replicated even if the source table is not. Supported values: The default value is FALSE.
        • OFFSET: The number of initial results to skip (this can be useful for paging through the results). The default value is '0'.
        • LIMIT: The number of records to keep. The default value is '-9999'.
        • ORDER_BY: Comma-separated list of the columns to be sorted by; e.g. 'timestamp asc, x desc'. The columns specified must be present in columnNames. If any alias is given for any column name, the alias must be used, rather than the original column name. The default value is ''.
        • CHUNK_SIZE: Indicates the number of records per chunk to be used for this projection.
        • CHUNK_COLUMN_MAX_MEMORY: Indicates the target maximum data size for each column in a chunk to be used for this projection.

        • SHARD_KEY: Comma-separated list of the columns to be sharded on; e.g. 'column1, column2'. The columns specified must be present in columnNames. If any alias is given for any column name, the alias must be used, rather than the original column name. The default value is ''.
        • PERSIST: If TRUE, then the projection specified in projectionName will be persisted and will not expire unless a TTL is specified. If FALSE, then the projection will be an in-memory table and will expire unless a TTL is specified otherwise. Supported values: The default value is FALSE.
        • PRESERVE_DICT_ENCODING: If TRUE, then columns that were dict encoded in the source table will be dict encoded in the projection. Supported values: The default value is TRUE.
        • RETAIN_PARTITIONS: Determines whether the created projection will retain the partitioning scheme from the source table. Supported values: The default value is FALSE.
        • PARTITION_TYPE: Partitioning scheme to use. Supported values:

        • JOIN_WINDOW_FUNCTIONS_THRESHOLD: If the projection is greater than this width (in bytes), then window functions which require a reshard will be computed separately and joined back together. The default value is ''.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.

                                                throws GPUdbException
        Creates a new external table, which is a local database object whose source data is located externally to the database. The source data can be located either in KiFS; on the cluster, accessible to the database; or remotely, accessible via a pre-defined external data source.

        The external table can have its structure defined explicitly, via createTableOptions, which contains many of the options from createTable; or defined implicitly, inferred from the source data.

        Parameters:
        tableName - Name of the table to be created, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria.
        filepaths - A list of file paths from which data will be sourced; For paths in KiFS, use the URI prefix of kifs:// followed by the path to a file or directory. File matching by prefix is supported, e.g. kifs://dir/file would match dir/file_1 and dir/file_2. When prefix matching is used, the path must start with a full, valid KiFS directory name. If an external data source is specified in DATASOURCE_NAME, these file paths must resolve to accessible files at that data source location. Prefix matching is supported. If the data source is hdfs, prefixes must be aligned with directories, i.e. partial file names will not match. If no data source is specified, the files are assumed to be local to the database and must all be accessible to the gpudb user, residing on the path (or relative to the path) specified by the external files directory in the Kinetica configuration file. Wildcards (*) can be used to specify a group of files. Prefix matching is supported, the prefixes must be aligned with directories. If the first path ends in .tsv, the text delimiter will be defaulted to a tab character. If the first path ends in .psv, the text delimiter will be defaulted to a pipe character (|).
        modifyColumns - Not implemented yet. The default value is an empty Map.
        createTableOptions - Options from createTable, allowing the structure of the table to be defined independently of the data source. The default value is an empty Map.
        options - Optional parameters.
        • BAD_RECORD_TABLE_NAME: Name of a table to which records that were rejected are written. The bad-record-table has the following columns: line_number (long), line_rejected (string), error_message (string). When ERROR_HANDLING is ABORT, bad records table is not populated.
        • BAD_RECORD_TABLE_LIMIT: A positive integer indicating the maximum number of records that can be written to the bad-record-table. The default value is '10000'.
        • BAD_RECORD_TABLE_LIMIT_PER_INPUT: For subscriptions, a positive integer indicating the maximum number of records that can be written to the bad-record-table per file/payload. Default value will be BAD_RECORD_TABLE_LIMIT and total size of the table per rank is limited to BAD_RECORD_TABLE_LIMIT.
        • BATCH_SIZE: Number of records to insert per batch when inserting data. The default value is '50000'.
        • COLUMN_FORMATS: For each target column specified, applies the column-property-bound format to the source data loaded into that column. Each column format will contain a mapping of one or more of its column properties to an appropriate format for each property. Currently supported column properties include date, time, and datetime. The parameter value must be formatted as a JSON string of maps of column names to maps of column properties to their corresponding column formats, e.g., '{ "order_date" : { "date" : "%Y.%m.%d" }, "order_time" : { "time" : "%H:%M:%S" } }'. See DEFAULT_COLUMN_FORMATS for valid format syntax.
        • COLUMNS_TO_LOAD: Specifies a comma-delimited list of columns from the source data to load. If more than one file is being loaded, this list applies to all files. Column numbers can be specified discretely or as a range. For example, a value of '5,7,1..3' will insert values from the fifth column in the source data into the first column in the target table, from the seventh column in the source data into the second column in the target table, and from the first through third columns in the source data into the third through fifth columns in the target table. If the source data contains a header, column names matching the file header names may be provided instead of column numbers. If the target table doesn't exist, the table will be created with the columns in this order. If the target table does exist with columns in a different order than the source data, this list can be used to match the order of the target table. For example, a value of 'C, B, A' will create a three column table with column C, followed by column B, followed by column A; or will insert those fields in that order into a table created with columns in that order. If the target table exists, the column names must match the source data field names for a name-mapping to be successful. Mutually exclusive with COLUMNS_TO_SKIP.
        • COLUMNS_TO_SKIP: Specifies a comma-delimited list of columns from the source data to skip. Mutually exclusive with COLUMNS_TO_LOAD.
        • COMPRESSION_TYPE: Source data compression type. Supported values:
          • NONE: No compression.
          • AUTO: Auto detect compression type
          • GZIP: gzip file compression.
          • BZIP2: bzip2 file compression.
          The default value is AUTO.
        • DATASOURCE_NAME: Name of an existing external data source from which data file(s) specified in filepaths will be loaded
        • DEFAULT_COLUMN_FORMATS: Specifies the default format to be applied to source data loaded into columns with the corresponding column property. Currently supported column properties include date, time, and datetime. This default column-property-bound format can be overridden by specifying a column property and format for a given target column in COLUMN_FORMATS. For each specified annotation, the format will apply to all columns with that annotation unless a custom COLUMN_FORMATS for that annotation is specified. The parameter value must be formatted as a JSON string that is a map of column properties to their respective column formats, e.g., '{ "date" : "%Y.%m.%d", "time" : "%H:%M:%S" }'. Column formats are specified as a string of control characters and plain text. The supported control characters are 'Y', 'm', 'd', 'H', 'M', 'S', and 's', which follow the Linux 'strptime()' specification, as well as 's', which specifies seconds and fractional seconds (though the fractional component will be truncated past milliseconds). Formats for the 'date' annotation must include the 'Y', 'm', and 'd' control characters. Formats for the 'time' annotation must include the 'H', 'M', and either 'S' or 's' (but not both) control characters. Formats for the 'datetime' annotation meet both the 'date' and 'time' control character requirements. For example, '{"datetime" : "%m/%d/%Y %H:%M:%S" }' would be used to interpret text as "05/04/2000 12:12:11"
        • DATALAKE_CATALOG: Name of an existing datalake(iceberg) catalog used in loading files
        • DATALAKE_PATH: Path of datalake(iceberg) object
        • DATALAKE_SNAPSHOT: Snapshot ID of datalake(iceberg) object
        • ERROR_HANDLING: Specifies how errors should be handled upon insertion. Supported values:
          • PERMISSIVE: Records with missing columns are populated with nulls if possible; otherwise, the malformed records are skipped.
          • IGNORE_BAD_RECORDS: Malformed records are skipped.
          • ABORT: Stops current insertion and aborts entire operation when an error is encountered. Primary key collisions are considered abortable errors in this mode.
          The default value is ABORT.
        • EXTERNAL_TABLE_TYPE: Specifies whether the external table holds a local copy of the external data. Supported values:
          • MATERIALIZED: Loads a copy of the external data into the database, refreshed on demand
          • LOGICAL: External data will not be loaded into the database; the data will be retrieved from the source upon servicing each query against the external table
          The default value is MATERIALIZED.
        • FILE_TYPE: Specifies the type of the file(s) whose records will be inserted. Supported values:

          • SHAPEFILE: ShapeFile file format
          The default value is DELIMITED_TEXT.
        • FLATTEN_COLUMNS: Specifies how to handle nested columns. Supported values:
          • TRUE: Break up nested columns to multiple columns
          • FALSE: Treat nested columns as json columns instead of flattening
          The default value is FALSE.
        • GDAL_CONFIGURATION_OPTIONS: Comma separated list of gdal conf options, for the specific requests: key=value
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If FALSE, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by ERROR_HANDLING. If the specified table does not have a primary key or if upsert mode is in effect (UPDATE_ON_EXISTING_PK is TRUE), then this option has no effect. Supported values:
          • TRUE: Ignore new records whose primary key values collide with those of existing records
          • FALSE: Treat as errors any new records whose primary key values collide with those of existing records
          The default value is FALSE.
        • INGESTION_MODE: Whether to do a full load, dry run, or perform a type inference on the source data. Supported values:
          • FULL: Run a type inference on the source data (if needed) and ingest
          • DRY_RUN: Does not load data, but walks through the source data and determines the number of valid records, taking into account the current mode of ERROR_HANDLING.
          • TYPE_INFERENCE_ONLY: Infer the type of the source data and return, without ingesting any data. The inferred type is returned in the response.
          The default value is FULL.
        • JDBC_FETCH_SIZE: The JDBC fetch size, which determines how many rows to fetch per round trip. The default value is '50000'.
        • KAFKA_CONSUMERS_PER_RANK: Number of Kafka consumer threads per rank (valid range 1-6). The default value is '1'.
        • KAFKA_GROUP_ID: The group id to be used when consuming data from a Kafka topic (valid only for Kafka datasource subscriptions).
        • KAFKA_OFFSET_RESET_POLICY: Policy to determine whether the Kafka data consumption starts either at earliest offset or latest offset. Supported values: The default value is EARLIEST.
        • KAFKA_OPTIMISTIC_INGEST: Enable optimistic ingestion where Kafka topic offsets and table data are committed independently to achieve parallelism. Supported values: The default value is FALSE.
        • KAFKA_SUBSCRIPTION_CANCEL_AFTER: Sets the Kafka subscription lifespan (in minutes). Expired subscription will be cancelled automatically.
        • KAFKA_TYPE_INFERENCE_FETCH_TIMEOUT: Maximum time to collect Kafka messages before type inferencing on the set of them.
        • LAYER: Geo files layer(s) name(s): comma separated.
        • LOADING_MODE: Scheme for distributing the extraction and loading of data from the source data file(s). This option applies only when loading files that are local to the database. Supported values:
          • HEAD: The head node loads all data. All files must be available to the head node.
          • DISTRIBUTED_SHARED: The head node coordinates loading data by worker processes across all nodes from shared files available to all workers. NOTE: Instead of existing on a shared source, the files can be duplicated on a source local to each host to improve performance, though the files must appear as the same data set from the perspective of all hosts performing the load.
          • DISTRIBUTED_LOCAL: A single worker process on each node loads all files that are available to it. This option works best when each worker loads files from its own file system, to maximize performance. In order to avoid data duplication, either each worker performing the load needs to have visibility to a set of files unique to it (no file is visible to more than one node) or the target table needs to have a primary key (which will allow the worker to automatically deduplicate data). NOTE: If the target table doesn't exist, the table structure will be determined by the head node. If the head node has no files local to it, it will be unable to determine the structure and the request will fail. If the head node is configured to have no worker processes, no data strictly accessible to the head node will be loaded.
          The default value is HEAD.
        • LOCAL_TIME_OFFSET: Apply an offset to Avro local timestamp columns.
        • MAX_RECORDS_TO_LOAD: Limit the number of records to load in this request: if this number is larger than BATCH_SIZE, then the number of records loaded will be limited to the next whole number of BATCH_SIZE (per working thread).
        • NUM_TASKS_PER_RANK: Number of tasks for reading file per rank. Default will be system configuration parameter, external_file_reader_num_tasks.
        • POLL_INTERVAL: If TRUE, the number of seconds between attempts to load external files into the table. If zero, polling will be continuous as long as data is found. If no data is found, the interval will steadily increase to a maximum of 60 seconds. The default value is '0'.
        • PRIMARY_KEYS: Comma separated list of column names to set as primary keys, when not specified in the type.
        • REFRESH_METHOD: Method by which the table can be refreshed from its source data. Supported values:
          • MANUAL: Refresh only occurs when manually requested by invoking the refresh action of alterTable on this table.
          • ON_START: Refresh table on database startup and when manually requested by invoking the refresh action of alterTable on this table.
          The default value is MANUAL.
        • SCHEMA_REGISTRY_CONNECTION_RETRIES: Confluent Schema registry connection timeout (in Secs)
        • SCHEMA_REGISTRY_CONNECTION_TIMEOUT: Confluent Schema registry connection timeout (in Secs)
        • SCHEMA_REGISTRY_MAX_CONSECUTIVE_CONNECTION_FAILURES: Max records to skip due to SR connection failures, before failing
        • MAX_CONSECUTIVE_INVALID_SCHEMA_FAILURE: Max records to skip due to schema related errors, before failing
        • SCHEMA_REGISTRY_SCHEMA_NAME: Name of the Avro schema in the schema registry to use when reading Avro records.

        • SKIP_LINES: Skip a number of lines from the beginning of the file.
        • START_OFFSETS: Starting offsets by partition to fetch from kafka. A comma separated list of partition:offset pairs.
        • SUBSCRIBE: Continuously poll the data source to check for new data and load it into the table. Supported values: The default value is FALSE.
        • TABLE_INSERT_MODE: Insertion scheme to use when inserting records from multiple shapefiles. Supported values:
          • SINGLE: Insert all records into a single table.
          • TABLE_PER_FILE: Insert records from each file into a new table corresponding to that file.
          The default value is SINGLE.
        • TEXT_COMMENT_STRING: Specifies the character string that should be interpreted as a comment line prefix in the source data. All lines in the data starting with the provided string are ignored. For DELIMITED_TEXT FILE_TYPE only. The default value is '#'.
        • TEXT_DELIMITER: Specifies the character delimiting field values in the source data and field names in the header (if present). For DELIMITED_TEXT FILE_TYPE only. The default value is ','.
        • TEXT_ESCAPE_CHARACTER: Specifies the character that is used to escape other characters in the source data. An 'a', 'b', 'f', 'n', 'r', 't', or 'v' preceded by an escape character will be interpreted as the ASCII bell, backspace, form feed, line feed, carriage return, horizontal tab, and vertical tab, respectively. For example, the escape character followed by an 'n' will be interpreted as a newline within a field value. The escape character can also be used to escape the quoting character, and will be treated as an escape character whether it is within a quoted field value or not. For DELIMITED_TEXT FILE_TYPE only.
        • TEXT_HAS_HEADER: Indicates whether the source data contains a header row. For DELIMITED_TEXT FILE_TYPE only. Supported values: The default value is TRUE.
        • TEXT_HEADER_PROPERTY_DELIMITER: Specifies the delimiter for column properties in the header row (if present). Cannot be set to same value as TEXT_DELIMITER. For DELIMITED_TEXT FILE_TYPE only. The default value is '|'.
        • TEXT_NULL_STRING: Specifies the character string that should be interpreted as a null value in the source data. For DELIMITED_TEXT FILE_TYPE only. The default value is '\N'.
        • TEXT_QUOTE_CHARACTER: Specifies the character that should be interpreted as a field value quoting character in the source data. The character must appear at beginning and end of field value to take effect. Delimiters within quoted fields are treated as literals and not delimiters. Within a quoted field, two consecutive quote characters will be interpreted as a single literal quote character, effectively escaping it. To not have a quote character, specify an empty string. For DELIMITED_TEXT FILE_TYPE only. The default value is '"'.
        • TEXT_SEARCH_COLUMNS: Add 'text_search' property to internally inferenced string columns. Comma separated list of column names or '*' for all columns. To add 'text_search' property only to string columns greater than or equal to a minimum size, also set the TEXT_SEARCH_MIN_COLUMN_LENGTH
        • TEXT_SEARCH_MIN_COLUMN_LENGTH: Set the minimum column size for strings to apply the 'text_search' property to. Used only when TEXT_SEARCH_COLUMNS has a value.
        • TRIM_SPACE: If set to TRUE, remove leading or trailing space from fields. Supported values: The default value is FALSE.

        • TRUNCATE_TABLE: If set to TRUE, truncates the table specified by tableName prior to loading the file(s). Supported values: The default value is FALSE.
        • TYPE_INFERENCE_MAX_RECORDS_READ
        • TYPE_INFERENCE_MODE: Optimize type inferencing for either speed or accuracy. Supported values:
          • ACCURACY: Scans data to get exactly-typed and sized columns for all data scanned.
          • SPEED: Scans data and picks the widest possible column types so that 'all' values will fit with minimum data scanned
          The default value is SPEED.
        • REMOTE_QUERY: Remote SQL query from which data will be sourced
        • REMOTE_QUERY_FILTER_COLUMN: Name of column to be used for splitting REMOTE_QUERY into multiple sub-queries using the data distribution of given column
        • REMOTE_QUERY_INCREASING_COLUMN: Column on subscribed remote query result that will increase for new records (e.g., TIMESTAMP).
        • REMOTE_QUERY_PARTITION_COLUMN: Alias name for REMOTE_QUERY_FILTER_COLUMN.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to TRUE, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be 'upserted'). If set to FALSE, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by IGNORE_EXISTING_PK and ERROR_HANDLING. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Upsert new records when primary keys match existing records
          • FALSE: Reject new records when primary keys match existing records
          The default value is FALSE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

                                              throws GPUdbException
        Creates a monitor that watches for a single table modification event type (insert, update, or delete) on a particular table (identified by tableName) and forwards event notifications to subscribers via ZMQ. After this call completes, subscribe to the returned topicId on the ZMQ table monitor port (default 9002). Each time an operation of the given type on the table completes, a multipart message is published for that topic; the first part contains only the topic ID, and each subsequent part contains one binary-encoded Avro object that corresponds to the event and can be decoded using typeSchema. The monitor will continue to run (regardless of whether or not there are any subscribers) until deactivated with clearTableMonitor.

        For more information on table monitors, see Table Monitors.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        For more information on table monitors, see Table Monitors.

        Parameters:
        tableName - Name of the table to monitor, in [schema_name.]table_name format, using standard name resolution rules.
        options - Optional parameters.
        • EVENT: Type of modification event on the target table to be monitored by this table monitor. Supported values:
          • INSERT: Get notifications of new record insertions. The new row images are forwarded to the subscribers.
          • UPDATE: Get notifications of update operations. The modified row count information is forwarded to the subscribers.
          • DELETE: Get notifications of delete operations. The deleted row count information is forwarded to the subscribers.
          The default value is INSERT.
        • MONITOR_ID: ID to use for this monitor instead of a randomly generated one
        • DATASINK_NAME: Name of an existing data sink to send change data notifications to
        • DESTINATION: Destination for the output data in format 'destination_type://path[:port]'. Supported destination types are 'http', 'https' and 'kafka'.
        • KAFKA_TOPIC_NAME: Name of the Kafka topic to publish to if DESTINATION in options is specified and is a Kafka broker
        • INCREASING_COLUMN: Column on subscribed table that will increase for new records (e.g., TIMESTAMP).
        • EXPRESSION: Filter expression to limit records for notification
        • JOIN_TABLE_NAMES: A comma-separated list of tables (optionally with aliases) to include in the join. The monitored table tableName must be included, representing only the newly inserted rows (deltas) since the last notification. Other tables can be any existing tables or views. Aliases can be used with the 'table_name as alias' syntax.
        • JOIN_COLUMN_NAMES: A comma-separated list of columns or expressions to include from the joined tables. Column references can use table names or aliases defined in 'join_table_names'. Each column can optionally be aliased using 'as'. The selected columns will also appear in the notification output.
        • JOIN_EXPRESSIONS: Optional filter or join expressions to apply when combining the tables. Expressions are standard SQL-style conditions and can reference any table or alias listed in 'join_table_names'. This corresponds to the WHERE clause of the underlying join, and can include conditions to filter the delta rows.
        • REFRESH_METHOD: Method controlling when the table monitor reports changes to the tableName. Supported values: The default value is ON_CHANGE.
        • REFRESH_PERIOD: When REFRESH_METHOD is PERIODIC, specifies the period in seconds at which changes are reported.
        • REFRESH_START_TIME: When REFRESH_METHOD is PERIODIC, specifies the first time at which changes are reported. Value is a datetime string with format 'YYYY-MM-DD HH:MM:SS'.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

                                                throws GPUdbException
        Sets up an area trigger mechanism for two column_names for one or more tables. (This function is essentially the two-dimensional version of createTriggerByRange.) Once the trigger has been activated, any record added to the listed tables(s) via insertRecords with the chosen columns' values falling within the specified region will trip the trigger. All such records will be queued at the trigger port (by default '9001' but able to be retrieved via showSystemStatus) for any listening client to collect. Active triggers can be cancelled by using the clearTrigger endpoint or by clearing all relevant tables.

        The output returns the trigger handle as well as indicating success or failure of the trigger activation.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.

      • createType

        public CreateTypeResponse createType​(CreateTypeRequest request)
                              throws GPUdbException
        Creates a new type describing the columns of a table. The type definition is specified as a list of columns, each specified as a list of the column name, data type, and any column attributes.

        Example of a type definition with some parameters: 

        
     [
         ["id", "int8", "primary_key"],
         ["dept_id", "int8", "primary_key", "shard_key"],
         ["manager_id", "int8", "nullable"],
         ["first_name", "char32"],
         ["last_name", "char64"],
         ["salary", "decimal"],
         ["hire_date", "date"]
     ]
        Each column definition consists of the column name (which should meet the standard column naming criteria), the column's specific type (int, long, float, double, string, bytes, or any of the possible values for properties), and any data handling, data key, or data replacement properties.

        Note that some properties are mutually exclusive--i.e. they cannot be specified for any given column simultaneously. One example of mutually exclusive properties are PRIMARY_KEY and NULLABLE.

        A single primary key and/or single shard key can be set across one or more columns. If a primary key is specified, then a uniqueness constraint is enforced, in that only a single object can exist with a given primary key column value (or set of values for the key columns, if using a composite primary key). When inserting data into a table with a primary key, depending on the parameters in the request, incoming objects with primary key values that match existing objects will either overwrite (i.e. update) the existing object or will be skipped and not added into the set.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

         ["last_name", "char64"],
         ["salary", "decimal"],
         ["hire_date", "date"]
     ]
        Each column definition consists of the column name (which should meet the standard column naming criteria), the column's specific type (int, long, float, double, string, bytes, or any of the possible values for properties), and any data handling, data key, or data replacement properties.

        Note that some properties are mutually exclusive--i.e. they cannot be specified for any given column simultaneously. One example of mutually exclusive properties are PRIMARY_KEY and NULLABLE.

        A single primary key and/or single shard key can be set across one or more columns.

        Parameters:
        typeDefinition - a JSON string describing the columns of the type to be registered, as described above.
        label - A user-defined description string which can be used to differentiate between tables and types with otherwise identical schemas.
        properties - [DEPRECATED--please use these property values in the typeDefinition directly, as described at the top, instead] Each key-value pair specifies the properties to use for a given column where the key is the column name. All keys used must be relevant column names for the given table. Specifying any property overrides the default properties for that column (which is based on the column's data type). Valid values are:
        • DATA: Default property for all numeric and string type columns; makes the column available for GPU queries.
        • TEXT_SEARCH: Valid only for select 'string' columns. Enables full text search--see Full Text Search for details and applicable string column types.
        • TIMESTAMP: Valid only for 'long' columns. Indicates that this field represents a timestamp and will be provided in milliseconds since the Unix epoch: 00:00:00 Jan 1 1970. Dates represented by a timestamp must fall between the year 1000 and the year 2900.
        • ULONG: Valid only for 'string' columns. It represents an unsigned long integer data type. The string can only be interpreted as an unsigned long data type with minimum value of zero, and maximum value of 18446744073709551615.
        • UUID: Valid only for 'string' columns. It represents an uuid data type. Internally, it is stored as a 128-bit integer.
        • DECIMAL: Valid only for 'string' columns. It represents a SQL type NUMERIC(19, 4) data type. There can be up to 15 digits before the decimal point and up to four digits in the fractional part. The value can be positive or negative (indicated by a minus sign at the beginning). This property is mutually exclusive with the TEXT_SEARCH property.
        • DATE: Valid only for 'string' columns. Indicates that this field represents a date and will be provided in the format 'YYYY-MM-DD'. The allowable range is 1000-01-01 through 2900-01-01. This property is mutually exclusive with the TEXT_SEARCH property.
        • TIME: Valid only for 'string' columns. Indicates that this field represents a time-of-day and will be provided in the format 'HH:MM:SS.mmm'. The allowable range is 00:00:00.000 through 23:59:59.999. This property is mutually exclusive with the TEXT_SEARCH property.
        • DATETIME: Valid only for 'string' columns. Indicates that this field represents a datetime and will be provided in the format 'YYYY-MM-DD HH:MM:SS.mmm'. The allowable range is 1000-01-01 00:00:00.000 through 2900-01-01 23:59:59.999. This property is mutually exclusive with the TEXT_SEARCH property.
        • CHAR1: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 1 character.
        • CHAR2: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 2 characters.
        • CHAR4: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 4 characters.
        • CHAR8: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 8 characters.
        • CHAR16: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 16 characters.
        • CHAR32: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 32 characters.
        • CHAR64: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 64 characters.
        • CHAR128: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 128 characters.
        • CHAR256: This property provides optimized memory, disk and query performance for string columns. Strings with this property must be no longer than 256 characters.
        • BOOLEAN: This property provides optimized memory and query performance for int columns. Ints with this property must be between 0 and 1(inclusive)
        • INT8: This property provides optimized memory and query performance for int columns. Ints with this property must be between -128 and +127 (inclusive)
        • INT16: This property provides optimized memory and query performance for int columns. Ints with this property must be between -32768 and +32767 (inclusive)
        • IPV4: This property provides optimized memory, disk and query performance for string columns representing IPv4 addresses (i.e. 192.168.1.1). Strings with this property must be of the form: A.B.C.D where A, B, C and D are in the range of 0-255.
        • ARRAY: Valid only for 'string' columns. Indicates that this field contains an array. The value type and (optionally) the item count should be specified in parenthesis; e.g., 'array(int, 10)' for a 10-integer array. Both 'array(int)' and 'array(int, -1)' will designate an unlimited-length integer array, though no bounds checking is performed on arrays of any length.
        • JSON: Valid only for 'string' columns. Indicates that this field contains values in JSON format.
        • VECTOR: Valid only for 'bytes' columns. Indicates that this field contains a vector of floats. The length should be specified in parenthesis, e.g., 'vector(1000)'.
        • WKT: Valid only for 'string' and 'bytes' columns. Indicates that this field contains geospatial geometry objects in Well-Known Text (WKT) or Well-Known Binary (WKB) format.
        • PRIMARY_KEY: This property indicates that this column will be part of (or the entire) primary key.
        • SOFT_PRIMARY_KEY: This property indicates that this column will be part of (or the entire) soft primary key.
        • SHARD_KEY: This property indicates that this column will be part of (or the entire) shard key.
        • NULLABLE: This property indicates that this column is nullable. However, setting this property is insufficient for making the column nullable. The user must declare the type of the column as a union between its regular type and 'null' in the Avro schema for the record type in typeDefinition. For example, if a column is of type integer and is nullable, then the entry for the column in the Avro schema must be: ['int', 'null']. The C++, C#, Java, and Python APIs have built-in convenience for bypassing setting the Avro schema by hand. For those languages, one can use this property as usual and not have to worry about the Avro schema for the record.
        • COMPRESS: This property indicates that this column should be compressed with the given codec and optional level; e.g., 'compress(snappy)' for Snappy compression and 'compress(zstd(7))' for zstd level 7 compression. This property is primarily used in order to save disk space.
        • DICT: This property indicates that this column should be dictionary encoded. It can only be used in conjunction with restricted string (charN), int, long or date columns. Dictionary encoding is best for columns where the cardinality (the number of unique values) is expected to be low. This property can save a large amount of memory.
        • INIT_WITH_NOW: For 'date', 'time', 'datetime', or 'timestamp' column types, replace empty strings and invalid timestamps with 'NOW()' upon insert.
        • INIT_WITH_UUID: For 'uuid' type, replace empty strings and invalid UUID values with randomly-generated UUIDs upon insert.
        • UPDATE_WITH_NOW: For 'date', 'time', 'datetime', or 'timestamp' column types, always update the field with 'NOW()' upon any update.
        The default value is an empty Map.
        options - Optional parameters. The default value is an empty Map.

        • CHUNK_COLUMN_MAX_MEMORY: Indicates the target maximum data size for each column in a chunk to be used for this output table.
        • CHUNK_MAX_MEMORY: Indicates the target maximum data size for all columns in a chunk to be used for this output table.
        • CREATE_INDEXES: Comma-separated list of columns on which to create indexes on the output table. The columns specified must be present in outputColumnNames.
        • TTL: Sets the TTL of the output table specified in tableName.
        • PERSIST: If TRUE, then the output table specified in tableName will be persisted and will not expire unless a TTL is specified. If FALSE, then the output table will be an in-memory table and will expire unless a TTL is specified otherwise. Supported values: The default value is FALSE.
        • VIEW_ID: ID of view of which this output table is a member. The default value is ''.
        • FORCE_REPLICATED: If TRUE, then the output table specified in tableName will be replicated even if the source tables are not. Supported values: The default value is FALSE.
        • STRATEGY_DEFINITION: The tier strategy for the table and its columns.
        • COMPRESSION_CODEC: The default compression codec for this table's columns.
        • NO_COUNT: Return a count of 0 for the union table response to avoid the cost of counting; optimization needed for many chunk virtual_union's. The default value is 'false'.

                                throws GPUdbException
        Executes a proc. This endpoint is asynchronous and does not wait for the proc to complete before returning.

        If the proc being executed is distributed, inputTableNames and inputColumnNames may be passed to the proc to use for reading data, and outputTableNames may be passed to the proc to use for writing data.

        If the proc being executed is non-distributed, these table parameters will be ignored.

        Parameters:
        procName - Name of the proc to execute. Must be the name of a currently existing proc.
        params - A map containing named parameters to pass to the proc. Each key/value pair specifies the name of a parameter and its value. The default value is an empty Map.
        binParams - A map containing named binary parameters to pass to the proc. Each key/value pair specifies the name of a parameter and its value. The default value is an empty Map.
        inputTableNames - Names of the tables containing data to be passed to the proc. Each name specified must be the name of a currently existing table, in [schema_name.]table_name format, using standard name resolution rules. If no table names are specified, no data will be passed to the proc. This parameter is ignored if the proc has a non-distributed execution mode. The default value is an empty List.
        inputColumnNames - Map of table names from inputTableNames to lists of names of columns from those tables that will be passed to the proc. Each column name specified must be the name of an existing column in the corresponding table. If a table name from inputTableNames is not included, all columns from that table will be passed to the proc. This parameter is ignored if the proc has a non-distributed execution mode. The default value is an empty Map.
        outputTableNames - Names of the tables to which output data from the proc will be written, each in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. If a specified table does not exist, it will automatically be created with the same schema as the corresponding table (by order) from inputTableNames, excluding any primary and shard keys. If a specified table is a non-persistent result table, it must not have primary or shard keys. If no table names are specified, no output data can be returned from the proc. This parameter is ignored if the proc has a non-distributed execution mode. The default value is an empty List.
        options - Optional parameters. The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.

      • executeSqlRaw

        public RawExecuteSqlResponse executeSqlRaw​(ExecuteSqlRequest request)
                                    throws GPUdbException
        Execute a SQL statement (query, DML, or DDL).

        See SQL Support for the complete set of supported SQL commands.

        When a caller wants all the results from a large query (e.g., more than max_get_records_size records), they can make multiple calls to this endpoint using the offset and limit parameters to page through the results. Normally, this will execute the statement query each time. To avoid re-executing the query each time and to keep the results in the same order, the caller should specify a PAGING_TABLE name to hold the results of the query between calls and specify the PAGING_TABLE on subsequent calls. When this is done, the caller should clear the paging table and any other tables in the RESULT_TABLE_LIST (both returned in the response) when they are done paging through the results. pagingTable (and RESULT_TABLE_LIST) will be empty if no paging table was created (e.g., when all the query results were returned in the first call).

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        Execute a SQL statement (query, DML, or DDL).

        See SQL Support for the complete set of supported SQL commands.

        When a caller wants all the results from a large query (e.g., more than max_get_records_size records), they can make multiple calls to this endpoint using the offset and limit parameters to page through the results. Normally, this will execute the statement query each time. To avoid re-executing the query each time and to keep the results in the same order, the caller should specify a PAGING_TABLE name to hold the results of the query between calls and specify the PAGING_TABLE on subsequent calls. When this is done, the caller should clear the paging table and any other tables in the RESULT_TABLE_LIST (both returned in the response) when they are done paging through the results. pagingTable (and RESULT_TABLE_LIST) will be empty if no paging table was created (e.g., when all the query results were returned in the first call).

        Parameters:
        statement - SQL statement (query, DML, or DDL) to be executed
        offset - A positive integer indicating the number of initial results to skip (this can be useful for paging through the results). The default value is 0. The minimum allowed value is 0. The maximum allowed value is MAX_INT.
        limit - A positive integer indicating the maximum number of results to be returned, or END_OF_SET (-9999) to indicate that the maximum number of results allowed by the server should be returned. The number of records returned will never exceed the server's own limit, defined by the max_get_records_size parameter in the server configuration. Use hasMoreRecords to see if more records exist in the result to be fetched, and offset and limit to request subsequent pages of results. The default value is -9999.
        requestSchemaStr - Avro schema of data. The default value is ''.
        data - An array of binary-encoded data for the records to be binded to the SQL query. Or use QUERY_PARAMETERS to pass the data in JSON format. The default value is an empty List.
        options - Optional parameters.
        • COST_BASED_OPTIMIZATION: If FALSE, disables the cost-based optimization of the given query. Supported values: The default value is FALSE.
        • DISTRIBUTED_JOINS: If TRUE, enables the use of distributed joins in servicing the given query. Any query requiring a distributed join will succeed, though hints can be used in the query to change the distribution of the source data to allow the query to succeed. Supported values: The default value is FALSE.
        • DISTRIBUTED_OPERATIONS: If TRUE, enables the use of distributed operations in servicing the given query. Any query requiring a distributed join will succeed, though hints can be used in the query to change the distribution of the source data to allow the query to succeed. Supported values: The default value is FALSE.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting into or updating a table with a primary key, only used when primary key record collisions are rejected (UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record insert/update that is rejected for resulting in a primary key collision with an existing table record will be ignored with no error generated. If FALSE, the rejection of any insert/update for resulting in a primary key collision will cause an error to be reported. If the specified table does not have a primary key or if UPDATE_ON_EXISTING_PK is TRUE, then this option has no effect. Supported values:
          • TRUE: Ignore inserts/updates that result in primary key collisions with existing records
          • FALSE: Treat as errors any inserts/updates that result in primary key collisions with existing records
          The default value is FALSE.
        • LATE_MATERIALIZATION: If TRUE, Joins/Filters results will always be materialized ( saved to result tables format). Supported values: The default value is FALSE.
        • PAGING_TABLE: When specified (or PAGING_TABLE_TTL is set), the system will create a paging table to hold the results of the query, when the output has more records than are in the response (i.e., when hasMoreRecords is TRUE). If the specified paging table exists, the records from the paging table are returned without re-evaluating the query. It is the caller's responsibility to clear the pagingTable and other tables in the RESULT_TABLE_LIST (both returned in the response) when they are done with this query.
        • PAGING_TABLE_TTL: Sets the TTL of the paging table. -1 indicates no timeout. Setting this option will cause a paging table to be generated when needed. The pagingTable and other tables in the RESULT_TABLE_LIST (both returned in the response) will be automatically cleared after the TTL expires, if set to a positive number. However, it is still recommended that the caller clear these tables when they are done with this query.
        • PARALLEL_EXECUTION: If FALSE, disables the parallel step execution of the given query. Supported values: The default value is TRUE.
        • PLAN_CACHE: If FALSE, disables plan caching for the given query. Supported values: The default value is TRUE.
        • PREPARE_MODE: If TRUE, compiles a query into an execution plan and saves it in query cache. Query execution is not performed and an empty response will be returned to user. Supported values: The default value is FALSE.
        • PRESERVE_DICT_ENCODING: If TRUE, then columns that were dict encoded in the source table will be dict encoded in the projection table. Supported values: The default value is TRUE.
        • QUERY_PARAMETERS: Query parameters in JSON array or arrays (for inserting multiple rows). This can be used instead of data and requestSchemaStr.
        • RESULTS_CACHING: If FALSE, disables caching of the results of the given query. Supported values: The default value is TRUE.
        • RULE_BASED_OPTIMIZATION: If FALSE, disables rule-based rewrite optimizations for the given query. Supported values: The default value is TRUE.
        • SSQ_OPTIMIZATION: If FALSE, scalar subqueries will be translated into joins. Supported values: The default value is TRUE.
        • TTL: Sets the TTL of the intermediate result tables used in query execution.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into or updating a table with a primary key. If set to TRUE, any existing table record with primary key values that match those of a record being inserted or updated will be replaced by that record. If set to FALSE, any such primary key collision will result in the insert/update being rejected and the error handled as determined by IGNORE_EXISTING_PK. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Replace the collided-into record with the record inserted or updated when a new/modified record causes a primary key collision with an existing record
          • FALSE: Reject the insert or update when it results in a primary key collision with an existing record
          The default value is FALSE.
        • VALIDATE_CHANGE_COLUMN: When changing a column using alter table, validate the change before applying it. If TRUE, then validate all values. A value too large (or too long) for the new type will prevent any change. If FALSE, then when a value is too large or long, it will be truncated. Supported values: The default value is TRUE.
        • CURRENT_SCHEMA: Use the supplied value as the default schema when processing this SQL command.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        Export records from a table to files. All tables can be exported, in full or partial (see COLUMNS_TO_EXPORT and COLUMNS_TO_SKIP). Additional filtering can be applied when using export table with expression through SQL. Default destination is KIFS, though other storage types (Azure, S3, GCS, and HDFS) are supported through DATASINK_NAME; see createDatasink.

        Server's local file system is not supported. Default file format is delimited text. See options for different file types and different options for each file type. Table is saved to a single file if within max file size limits (may vary depending on datasink type). If not, then table is split into multiple files; these may be smaller than the max size limit.

        All filenames created are returned in the response.

        Parameters:
        tableName -
        filepath - Path to data export target. If filepath has a file extension, it is read as the name of a file. If filepath is a directory, then the source table name with a random UUID appended will be used as the name of each exported file, all written to that directory. If filepath is a filename, then all exported files will have a random UUID appended to the given name. In either case, the target directory specified or implied must exist. The names of all exported files are returned in the response.
        options - Optional parameters.
        • BATCH_SIZE: Number of records to be exported as a batch. The default value is '1000000'.
        • COLUMN_FORMATS: For each source column specified, applies the column-property-bound format. Currently supported column properties include date, time, and datetime. The parameter value must be formatted as a JSON string of maps of column names to maps of column properties to their corresponding column formats, e.g., '{ "order_date" : { "date" : "%Y.%m.%d" }, "order_time" : { "time" : "%H:%M:%S" } }'. See DEFAULT_COLUMN_FORMATS for valid format syntax.
        • COLUMNS_TO_EXPORT: Specifies a comma-delimited list of columns from the source table to export, written to the output file in the order they are given. Column names can be provided, in which case the target file will use those names as the column headers as well. Alternatively, column numbers can be specified--discretely or as a range. For example, a value of '5,7,1..3' will write values from the fifth column in the source table into the first column in the target file, from the seventh column in the source table into the second column in the target file, and from the first through third columns in the source table into the third through fifth columns in the target file. Mutually exclusive with COLUMNS_TO_SKIP.
        • COLUMNS_TO_SKIP: Comma-separated list of column names or column numbers to not export. All columns in the source table not specified will be written to the target file in the order they appear in the table definition. Mutually exclusive with COLUMNS_TO_EXPORT.
        • DATASINK_NAME: Datasink name, created using createDatasink.
        • DEFAULT_COLUMN_FORMATS: Specifies the default format to use to write data. Currently supported column properties include date, time, and datetime. This default column-property-bound format can be overridden by specifying a column property and format for a given source column in COLUMN_FORMATS. For each specified annotation, the format will apply to all columns with that annotation unless custom COLUMN_FORMATS for that annotation are specified. The parameter value must be formatted as a JSON string that is a map of column properties to their respective column formats, e.g., '{ "date" : "%Y.%m.%d", "time" : "%H:%M:%S" }'. Column formats are specified as a string of control characters and plain text. The supported control characters are 'Y', 'm', 'd', 'H', 'M', 'S', and 's', which follow the Linux 'strptime()' specification, as well as 's', which specifies seconds and fractional seconds (though the fractional component will be truncated past milliseconds). Formats for the 'date' annotation must include the 'Y', 'm', and 'd' control characters. Formats for the 'time' annotation must include the 'H', 'M', and either 'S' or 's' (but not both) control characters. Formats for the 'datetime' annotation meet both the 'date' and 'time' control character requirements. For example, '{"datetime" : "%m/%d/%Y %H:%M:%S" }' would be used to write text as "05/04/2000 12:12:11"
        • EXPORT_DDL: Save DDL to a separate file. The default value is 'false'.
        • FILE_EXTENSION: Extension to give the export file. The default value is '.csv'.
        • FILE_TYPE: Specifies the file format to use when exporting data. Supported values: The default value is DELIMITED_TEXT.
        • KINETICA_HEADER: Whether to include a Kinetica proprietary header. Will not be written if TEXT_HAS_HEADER is FALSE. Supported values: The default value is FALSE.
        • KINETICA_HEADER_DELIMITER: If a Kinetica proprietary header is included, then specify a property separator. Different from column delimiter. The default value is '|'.
        • COMPRESSION_TYPE: File compression type. GZip can be applied to text and Parquet files. Snappy can only be applied to Parquet files, and is the default compression for them. Supported values:
        • SINGLE_FILE: Save records to a single file. This option may be ignored if file size exceeds internal file size limits (this limit will differ on different targets). Supported values: The default value is TRUE.
        • SINGLE_FILE_MAX_SIZE: Max file size (in MB) to allow saving to a single file. May be overridden by target limitations. The default value is ''.
        • TEXT_DELIMITER: Specifies the character to write out to delimit field values and field names in the header (if present). For DELIMITED_TEXT FILE_TYPE only. The default value is ','.
        • TEXT_HAS_HEADER: Indicates whether to write out a header row. For DELIMITED_TEXT FILE_TYPE only. Supported values: The default value is TRUE.
        • TEXT_NULL_STRING: Specifies the character string that should be written out for the null value in the data. For DELIMITED_TEXT FILE_TYPE only. The default value is '\N'.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.

        public FilterByListResponse filterByList​(FilterByListRequest request)
                                  throws GPUdbException
        Calculates which records from a table have values in the given list for the corresponding column. The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set (view) which satisfies the input filter specification is also created if a viewName is passed in as part of the request.

        For example, if a type definition has the columns 'x' and 'y', then a filter by list query with the column map {"x":["10.1", "2.3"], "y":["0.0", "-31.5", "42.0"]} will return the count of all data points whose x and y values match both in the respective x- and y-lists, e.g., "x = 10.1 and y = 0.0", "x = 2.3 and y = -31.5", etc. However, a record with "x = 10.1 and y = -31.5" or "x = 2.3 and y = 0.0" would not be returned because the values in the given lists do not correspond.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.

        Calculates which objects from a table or view match a string expression for the given string columns. Setting CASE_SENSITIVE can modify case sensitivity in matching for all modes except SEARCH. For SEARCH mode details and limitations, see Full Text Search.
        Parameters:
        tableName - Name of the table on which the filter operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table or view.
        viewName - If provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing table or view. The default value is ''.
        expression - The expression with which to filter the table.
        mode - The string filtering mode to apply. See below for details. Supported values:
        • SEARCH: Full text search query with wildcards and boolean operators. Note that for this mode, no column can be specified in columnNames; all string columns of the table that have text search enabled will be searched.
        • EQUALS: Exact whole-string match (accelerated).
        • CONTAINS: Partial substring match (not accelerated). If the column is a string type (non-charN) and the number of records is too large, it will return 0.
        • STARTS_WITH: Strings that start with the given expression (not accelerated). If the column is a string type (non-charN) and the number of records is too large, it will return 0.
        • REGEX: Full regular expression search (not accelerated). If the column is a string type (non-charN) and the number of records is too large, it will return 0.
        columnNames - List of columns on which to apply the filter. Ignored for SEARCH mode.
        options - Optional parameters.
        • CREATE_TEMP_TABLE: If TRUE, a unique temporary table name will be generated in the sys_temp schema and used in place of viewName. This is always allowed even if the caller does not have permission to create tables. The generated name is returned in QUALIFIED_VIEW_NAME. Supported values: The default value is FALSE.
        • COLLECTION_NAME: [DEPRECATED--please specify the containing schema for the view as part of viewName and use createSchema to create the schema if non-existent] Name of a schema for the newly created view. If the schema is non-existent, it will be automatically created.
        • CASE_SENSITIVE: If FALSE then string filtering will ignore case. Does not apply to SEARCH mode. Supported values: The default value is TRUE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

      • filterByTable

        public FilterByTableResponse filterByTable​(FilterByTableRequest request)
                                    throws GPUdbException
        Filters objects in one table based on objects in another table. The user must specify matching column types from the two tables (i.e. the target table from which objects will be filtered and the source table based on which the filter will be created); the column names need not be the same. If a viewName is specified, then the filtered objects will then be put in a newly created view. The operation is synchronous, meaning that a response will not be returned until all objects are fully available in the result view. The return value contains the count (i.e. the size) of the resulting view.
        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:

                                    throws GPUdbException
        Calculates which objects from a table has a particular value for a particular column. The input parameters provide a way to specify either a String or a Double valued column and a desired value for the column on which the filter is performed. The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new result view which satisfies the input filter restriction specification is also created with a view name passed in as part of the input payload. Although this functionality can also be accomplished with the standard filter function, it is more efficient.
        Parameters:
        request - Request object containing the parameters for the operation.

        For a given table, retrieves the values from the requested column(s). Maps of column name to the array of values as well as the column data type are returned. This endpoint supports pagination with the offset and limit parameters.

        Window functions, which can perform operations like moving averages, are available through this endpoint as well as createProjection.

        When using pagination, if the table (or the underlying table in the case of a view) is modified (records are inserted, updated, or deleted) during a call to the endpoint, the records or values retrieved may differ between calls based on the type of the update, e.g., the contiguity across pages cannot be relied upon.

        If tableName is empty, selection is performed against a single-row virtual table. This can be useful in executing temporal (NOW()), identity (USER()), or constant-based functions (GEODIST(-77.11, 38.88, -71.06, 42.36)).

        The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.

        If tableName is empty, selection is performed against a single-row virtual table. This can be useful in executing temporal (NOW()), identity (USER()), or constant-based functions (GEODIST(-77.11, 38.88, -71.06, 42.36)).

        The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        For a given table, retrieves the values from the requested column(s). Maps of column name to the array of values as well as the column data type are returned. This endpoint supports pagination with the offset and limit parameters.

        Window functions, which can perform operations like moving averages, are available through this endpoint as well as createProjection.

        When using pagination, if the table (or the underlying table in the case of a view) is modified (records are inserted, updated, or deleted) during a call to the endpoint, the records or values retrieved may differ between calls based on the type of the update, e.g., the contiguity across pages cannot be relied upon.

        If tableName is empty, selection is performed against a single-row virtual table. This can be useful in executing temporal (NOW()), identity (USER()), or constant-based functions (GEODIST(-77.11, 38.88, -71.06, 42.36)).

        The response is returned as a dynamic schema. For details see: dynamic schemas documentation.

        Parameters:
        tableName - Name of the table or view on which this operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. An empty table name retrieves one record from a single-row virtual table, where columns specified should be constants or constant expressions.
        columnNames - The list of column values to retrieve.
        offset - A positive integer indicating the number of initial results to skip (this can be useful for paging through the results). The default value is 0. The minimum allowed value is 0. The maximum allowed value is MAX_INT.
        limit - A positive integer indicating the maximum number of results to be returned, or END_OF_SET (-9999) to indicate that the maximum number of results allowed by the server should be returned. The number of records returned will never exceed the server's own limit, defined by the max_get_records_size parameter in the server configuration. Use hasMoreRecords to see if more records exist in the result to be fetched, and offset and limit to request subsequent pages of results. The default value is -9999.
        options - The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

                                                    throws GPUdbException
        Retrieves the complete series/track records from the given worldTableName based on the partial track information contained in the tableName.

        This operation supports paging through the data via the offset and limit parameters.

        In contrast to getRecordsRaw this returns records grouped by series/track. So if offset is 0 and limit is 5 this operation would return the first 5 series/tracks in tableName. Each series/track will be returned sorted by their TIMESTAMP column.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        Parameters:
        tableName - Name of table to which the records are to be added, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.
        data - An array of binary-encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if listEncoding is JSON.
        options - Optional parameters.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to TRUE, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be "upserted"). If set to FALSE, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by IGNORE_EXISTING_PK, ALLOW_PARTIAL_BATCH, and RETURN_INDIVIDUAL_ERRORS. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Upsert new records when primary keys match existing records
          • FALSE: Reject new records when primary keys match existing records
          The default value is FALSE.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If FALSE, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by ALLOW_PARTIAL_BATCH and RETURN_INDIVIDUAL_ERRORS. If the specified table does not have a primary key or if upsert mode is in effect (UPDATE_ON_EXISTING_PK is TRUE), then this option has no effect. Supported values:
          • TRUE: Ignore new records whose primary key values collide with those of existing records
          • FALSE: Treat as errors any new records whose primary key values collide with those of existing records
          The default value is FALSE.
        • PK_CONFLICT_PREDICATE_HIGHER: The record with higher value for the column resolves the primary-key insert conflict. The default value is ''.
        • PK_CONFLICT_PREDICATE_LOWER: The record with lower value for the column resolves the primary-key insert conflict. The default value is ''.
        • RETURN_RECORD_IDS: If TRUE then return the internal record id along for each inserted record. Supported values: The default value is FALSE.
        • TRUNCATE_STRINGS: If set to TRUE, any strings which are too long for their target charN string columns will be truncated to fit. Supported values: The default value is FALSE.
        • RETURN_INDIVIDUAL_ERRORS: If set to TRUE, success will always be returned, and any errors found will be included in the info map. The "bad_record_indices" entry is a comma-separated list of bad records (0-based). And if so, there will also be an "error_N" entry for each record with an error, where N is the index (0-based). Supported values: The default value is FALSE.
        • ALLOW_PARTIAL_BATCH: If set to TRUE, all correct records will be inserted and incorrect records will be rejected and reported. Otherwise, the entire batch will be rejected if any records are incorrect. Supported values: The default value is FALSE.
        • DRY_RUN: If set to TRUE, no data will be saved and any errors will be returned. Supported values: The default value is FALSE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        Adds multiple records to the specified table. The operation is synchronous, meaning that a response will not be returned until all the records are fully inserted and available. The response payload provides the counts of the number of records actually inserted and/or updated, and can provide the unique identifier of each added record.

        The options parameter can be used to customize this function's behavior.

        The UPDATE_ON_EXISTING_PK option specifies the record collision policy for inserting into a table with a primary key, but is ignored if no primary key exists.

        The RETURN_RECORD_IDS option indicates that the database should return the unique identifiers of inserted records.

        Type Parameters:
        TRequest - The type of object being added.
        Parameters:
        typeObjectMap - Type object map used for encoding input objects.
        tableName - Name of table to which the records are to be added, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.
        data - An array of binary-encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if listEncoding is JSON.
        options - Optional parameters.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to TRUE, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be "upserted"). If set to FALSE, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by IGNORE_EXISTING_PK, ALLOW_PARTIAL_BATCH, and RETURN_INDIVIDUAL_ERRORS. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Upsert new records when primary keys match existing records
          • FALSE: Reject new records when primary keys match existing records
          The default value is FALSE.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If FALSE, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by ALLOW_PARTIAL_BATCH and RETURN_INDIVIDUAL_ERRORS.

        Reads from one or more files and inserts the data into a new or existing table. The source data can be located either in KiFS; on the cluster, accessible to the database; or remotely, accessible via a pre-defined external data source.

        For delimited text files, there are two loading schemes: positional and name-based. The name-based loading scheme is enabled when the file has a header present and TEXT_HAS_HEADER is set to TRUE. In this scheme, the source file(s) field names must match the target table's column names exactly; however, the source file can have more fields than the target table has columns. If ERROR_HANDLING is set to PERMISSIVE, the source file can have fewer fields than the target table has columns. If the name-based loading scheme is being used, names matching the file header's names may be provided to COLUMNS_TO_LOAD instead of numbers, but ranges are not supported.

        Note: Due to data being loaded in parallel, there is no insertion order guaranteed. For tables with primary keys, in the case of a primary key collision, this means it is indeterminate which record will be inserted first and remain, while the rest of the colliding key records are discarded.

        Returns once all files are processed.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:

        Reads from one or more files and inserts the data into a new or existing table. The source data can be located either in KiFS; on the cluster, accessible to the database; or remotely, accessible via a pre-defined external data source.

        For delimited text files, there are two loading schemes: positional and name-based. The name-based loading scheme is enabled when the file has a header present and TEXT_HAS_HEADER is set to TRUE. In this scheme, the source file(s) field names must match the target table's column names exactly; however, the source file can have more fields than the target table has columns. If ERROR_HANDLING is set to PERMISSIVE, the source file can have fewer fields than the target table has columns. If the name-based loading scheme is being used, names matching the file header's names may be provided to COLUMNS_TO_LOAD instead of numbers, but ranges are not supported.

        Note: Due to data being loaded in parallel, there is no insertion order guaranteed. For tables with primary keys, in the case of a primary key collision, this means it is indeterminate which record will be inserted first and remain, while the rest of the colliding key records are discarded.

        Returns once all files are processed.

        Parameters:
        tableName - Name of the table into which the data will be inserted, in [schema_name.]table_name format, using standard name resolution rules. If the table does not exist, the table will be created using either an existing TYPE_ID or the type inferred from the file, and the new table name will have to meet standard table naming criteria.
        filepaths - A list of file paths from which data will be sourced; For paths in KiFS, use the URI prefix of kifs:// followed by the path to a file or directory. File matching by prefix is supported, e.g. kifs://dir/file would match dir/file_1 and dir/file_2. When prefix matching is used, the path must start with a full, valid KiFS directory name. If an external data source is specified in DATASOURCE_NAME, these file paths must resolve to accessible files at that data source location. Prefix matching is supported. If the data source is hdfs, prefixes must be aligned with directories, i.e. partial file names will not match. If no data source is specified, the files are assumed to be local to the database and must all be accessible to the gpudb user, residing on the path (or relative to the path) specified by the external files directory in the Kinetica configuration file. Wildcards (*) can be used to specify a group of files. Prefix matching is supported, the prefixes must be aligned with directories. If the first path ends in .tsv, the text delimiter will be defaulted to a tab character. If the first path ends in .psv, the text delimiter will be defaulted to a pipe character (|).
        modifyColumns - Not implemented yet. The default value is an empty Map.
        createTableOptions - Options from createTable, allowing the structure of the table to be defined independently of the data source, when creating the target table. The default value is an empty Map.
        options - Optional parameters.
        • BAD_RECORD_TABLE_NAME: Name of a table to which records that were rejected are written. The bad-record-table has the following columns: line_number (long), line_rejected (string), error_message (string). When ERROR_HANDLING is ABORT, bad records table is not populated.
        • BAD_RECORD_TABLE_LIMIT: A positive integer indicating the maximum number of records that can be written to the bad-record-table. The default value is '10000'.
        • BAD_RECORD_TABLE_LIMIT_PER_INPUT: For subscriptions, a positive integer indicating the maximum number of records that can be written to the bad-record-table per file/payload. Default value will be BAD_RECORD_TABLE_LIMIT and total size of the table per rank is limited to BAD_RECORD_TABLE_LIMIT.
        • BATCH_SIZE: Number of records to insert per batch when inserting data. The default value is '50000'.
        • COLUMN_FORMATS: For each target column specified, applies the column-property-bound format to the source data loaded into that column. Each column format will contain a mapping of one or more of its column properties to an appropriate format for each property. Currently supported column properties include date, time, and datetime. The parameter value must be formatted as a JSON string of maps of column names to maps of column properties to their corresponding column formats, e.g., '{ "order_date" : { "date" : "%Y.%m.%d" }, "order_time" : { "time" : "%H:%M:%S" } }'. See DEFAULT_COLUMN_FORMATS for valid format syntax.
        • COLUMNS_TO_LOAD: Specifies a comma-delimited list of columns from the source data to load. If more than one file is being loaded, this list applies to all files. Column numbers can be specified discretely or as a range. For example, a value of '5,7,1..3' will insert values from the fifth column in the source data into the first column in the target table, from the seventh column in the source data into the second column in the target table, and from the first through third columns in the source data into the third through fifth columns in the target table. If the source data contains a header, column names matching the file header names may be provided instead of column numbers. If the target table doesn't exist, the table will be created with the columns in this order. If the target table does exist with columns in a different order than the source data, this list can be used to match the order of the target table. For example, a value of 'C, B, A' will create a three column table with column C, followed by column B, followed by column A; or will insert those fields in that order into a table created with columns in that order. If the target table exists, the column names must match the source data field names for a name-mapping to be successful. Mutually exclusive with COLUMNS_TO_SKIP.
        • COLUMNS_TO_SKIP: Specifies a comma-delimited list of columns from the source data to skip. Mutually exclusive with COLUMNS_TO_LOAD.
        • COMPRESSION_TYPE: Source data compression type. Supported values:
          • NONE: No compression.
          • AUTO: Auto detect compression type
          • GZIP: gzip file compression.
          • BZIP2: bzip2 file compression.
          The default value is AUTO.
        • DATASOURCE_NAME: Name of an existing external data source from which data file(s) specified in filepaths will be loaded
        • DEFAULT_COLUMN_FORMATS: Specifies the default format to be applied to source data loaded into columns with the corresponding column property. Currently supported column properties include date, time, and datetime. This default column-property-bound format can be overridden by specifying a column property and format for a given target column in COLUMN_FORMATS. For each specified annotation, the format will apply to all columns with that annotation unless a custom COLUMN_FORMATS for that annotation is specified. The parameter value must be formatted as a JSON string that is a map of column properties to their respective column formats, e.g., '{ "date" : "%Y.%m.%d", "time" : "%H:%M:%S" }'. Column formats are specified as a string of control characters and plain text. The supported control characters are 'Y', 'm', 'd', 'H', 'M', 'S', and 's', which follow the Linux 'strptime()' specification, as well as 's', which specifies seconds and fractional seconds (though the fractional component will be truncated past milliseconds). Formats for the 'date' annotation must include the 'Y', 'm', and 'd' control characters. Formats for the 'time' annotation must include the 'H', 'M', and either 'S' or 's' (but not both) control characters. Formats for the 'datetime' annotation meet both the 'date' and 'time' control character requirements. For example, '{"datetime" : "%m/%d/%Y %H:%M:%S" }' would be used to interpret text as "05/04/2000 12:12:11"
        • ERROR_HANDLING: Specifies how errors should be handled upon insertion. Supported values:
          • PERMISSIVE: Records with missing columns are populated with nulls if possible; otherwise, the malformed records are skipped.
          • IGNORE_BAD_RECORDS: Malformed records are skipped.
          • ABORT: Stops current insertion and aborts entire operation when an error is encountered. Primary key collisions are considered abortable errors in this mode.
          The default value is ABORT.
        • FILE_TYPE: Specifies the type of the file(s) whose records will be inserted. Supported values:
          • AVRO: Avro file format
          • DELIMITED_TEXT: Delimited text file format; e.g., CSV, TSV, PSV, etc.
          • GDB: Esri/GDB file format
          • JSON: Json file format
          • PARQUET: Apache Parquet file format
          • SHAPEFILE: ShapeFile file format
          The default value is DELIMITED_TEXT.
        • FLATTEN_COLUMNS: Specifies how to handle nested columns. Supported values:
          • TRUE: Break up nested columns to multiple columns
          • FALSE: Treat nested columns as json columns instead of flattening
          The default value is FALSE.
        • GDAL_CONFIGURATION_OPTIONS: Comma separated list of gdal conf options, for the specific requests: key=value
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If FALSE, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by ERROR_HANDLING. If the specified table does not have a primary key or if upsert mode is in effect (UPDATE_ON_EXISTING_PK is TRUE), then this option has no effect. Supported values:
          • TRUE: Ignore new records whose primary key values collide with those of existing records
          • FALSE: Treat as errors any new records whose primary key values collide with those of existing records
          The default value is FALSE.
        • INGESTION_MODE: Whether to do a full load, dry run, or perform a type inference on the source data. Supported values:
          • FULL: Run a type inference on the source data (if needed) and ingest
          • DRY_RUN: Does not load data, but walks through the source data and determines the number of valid records, taking into account the current mode of ERROR_HANDLING.
          • TYPE_INFERENCE_ONLY: Infer the type of the source data and return, without ingesting any data. The inferred type is returned in the response.
          The default value is FULL.
        • KAFKA_CONSUMERS_PER_RANK: Number of Kafka consumer threads per rank (valid range 1-6). The default value is '1'.
        • KAFKA_GROUP_ID: The group id to be used when consuming data from a Kafka topic (valid only for Kafka datasource subscriptions).
        • KAFKA_OFFSET_RESET_POLICY: Policy to determine whether the Kafka data consumption starts either at earliest offset or latest offset. Supported values: The default value is EARLIEST.
        • KAFKA_OPTIMISTIC_INGEST: Enable optimistic ingestion where Kafka topic offsets and table data are committed independently to achieve parallelism. Supported values: The default value is FALSE.
        • KAFKA_SUBSCRIPTION_CANCEL_AFTER: Sets the Kafka subscription lifespan (in minutes). Expired subscription will be cancelled automatically.
        • KAFKA_TYPE_INFERENCE_FETCH_TIMEOUT: Maximum time to collect Kafka messages before type inferencing on the set of them.
        • LAYER: Geo files layer(s) name(s): comma separated.
        • LOADING_MODE: Scheme for distributing the extraction and loading of data from the source data file(s). This option applies only when loading files that are local to the database. Supported values:
          • HEAD: The head node loads all data. All files must be available to the head node.
          • DISTRIBUTED_SHARED: The head node coordinates loading data by worker processes across all nodes from shared files available to all workers. NOTE: Instead of existing on a shared source, the files can be duplicated on a source local to each host to improve performance, though the files must appear as the same data set from the perspective of all hosts performing the load.
          • DISTRIBUTED_LOCAL: A single worker process on each node loads all files that are available to it. This option works best when each worker loads files from its own file system, to maximize performance. In order to avoid data duplication, either each worker performing the load needs to have visibility to a set of files unique to it (no file is visible to more than one node) or the target table needs to have a primary key (which will allow the worker to automatically deduplicate data). NOTE: If the target table doesn't exist, the table structure will be determined by the head node. If the head node has no files local to it, it will be unable to determine the structure and the request will fail. If the head node is configured to have no worker processes, no data strictly accessible to the head node will be loaded.
          The default value is HEAD.
        • LOCAL_TIME_OFFSET: Apply an offset to Avro local timestamp columns.
        • MAX_RECORDS_TO_LOAD: Limit the number of records to load in this request: if this number is larger than BATCH_SIZE, then the number of records loaded will be limited to the next whole number of BATCH_SIZE (per working thread).
        • NUM_TASKS_PER_RANK: Number of tasks for reading file per rank. Default will be system configuration parameter, external_file_reader_num_tasks.
        • POLL_INTERVAL: If TRUE, the number of seconds between attempts to load external files into the table. If zero, polling will be continuous as long as data is found. If no data is found, the interval will steadily increase to a maximum of 60 seconds. The default value is '0'.
        • PRIMARY_KEYS: Comma separated list of column names to set as primary keys, when not specified in the type.
        • SCHEMA_REGISTRY_CONNECTION_RETRIES: Confluent Schema registry connection timeout (in Secs)
        • SCHEMA_REGISTRY_CONNECTION_TIMEOUT: Confluent Schema registry connection timeout (in Secs)
        • SCHEMA_REGISTRY_MAX_CONSECUTIVE_CONNECTION_FAILURES: Max records to skip due to SR connection failures, before failing
        • MAX_CONSECUTIVE_INVALID_SCHEMA_FAILURE: Max records to skip due to schema related errors, before failing
        • SCHEMA_REGISTRY_SCHEMA_NAME: Name of the Avro schema in the schema registry to use when reading Avro records.
        • SHARD_KEYS: Comma separated list of column names to set as shard keys, when not specified in the type.
        • SKIP_LINES: Skip a number of lines from the beginning of the file.
        • START_OFFSETS: Starting offsets by partition to fetch from kafka. A comma separated list of partition:offset pairs.
        • SUBSCRIBE: Continuously poll the data source to check for new data and load it into the table. Supported values: The default value is FALSE.
        • TABLE_INSERT_MODE: Insertion scheme to use when inserting records from multiple shapefiles. Supported values:
          • SINGLE: Insert all records into a single table.
          • TABLE_PER_FILE: Insert records from each file into a new table corresponding to that file.
          The default value is SINGLE.
        • TEXT_COMMENT_STRING: Specifies the character string that should be interpreted as a comment line prefix in the source data. All lines in the data starting with the provided string are ignored. For DELIMITED_TEXT FILE_TYPE only. The default value is '#'.
        • TEXT_DELIMITER: Specifies the character delimiting field values in the source data and field names in the header (if present). For DELIMITED_TEXT FILE_TYPE only. The default value is ','.
        • TEXT_ESCAPE_CHARACTER: Specifies the character that is used to escape other characters in the source data. An 'a', 'b', 'f', 'n', 'r', 't', or 'v' preceded by an escape character will be interpreted as the ASCII bell, backspace, form feed, line feed, carriage return, horizontal tab, and vertical tab, respectively. For example, the escape character followed by an 'n' will be interpreted as a newline within a field value. The escape character can also be used to escape the quoting character, and will be treated as an escape character whether it is within a quoted field value or not. For DELIMITED_TEXT FILE_TYPE only.
        • TEXT_HAS_HEADER: Indicates whether the source data contains a header row. For DELIMITED_TEXT FILE_TYPE only. Supported values: The default value is TRUE.
        • TEXT_HEADER_PROPERTY_DELIMITER: Specifies the delimiter for column properties in the header row (if present). Cannot be set to same value as TEXT_DELIMITER. For DELIMITED_TEXT FILE_TYPE only. The default value is '|'.
        • TEXT_NULL_STRING: Specifies the character string that should be interpreted as a null value in the source data. For DELIMITED_TEXT FILE_TYPE only. The default value is '\N'.
        • TEXT_QUOTE_CHARACTER: Specifies the character that should be interpreted as a field value quoting character in the source data. The character must appear at beginning and end of field value to take effect. Delimiters within quoted fields are treated as literals and not delimiters. Within a quoted field, two consecutive quote characters will be interpreted as a single literal quote character, effectively escaping it. To not have a quote character, specify an empty string. For DELIMITED_TEXT FILE_TYPE only. The default value is '"'.
        • TEXT_SEARCH_COLUMNS: Add 'text_search' property to internally inferenced string columns. Comma separated list of column names or '*' for all columns. To add 'text_search' property only to string columns greater than or equal to a minimum size, also set the TEXT_SEARCH_MIN_COLUMN_LENGTH
        • TEXT_SEARCH_MIN_COLUMN_LENGTH: Set the minimum column size for strings to apply the 'text_search' property to. Used only when TEXT_SEARCH_COLUMNS has a value.

          The default value is ACCURACY.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to TRUE, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be 'upserted'). If set to FALSE, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by IGNORE_EXISTING_PK and ERROR_HANDLING.

        Reads from the given text-based or binary payload and inserts the data into a new or existing table. The table will be created if it doesn't already exist.

        Returns once all records are processed.

        Parameters:
        tableName - Name of the table into which the data will be inserted, in [schema_name.]table_name format, using standard name resolution rules. If the table does not exist, the table will be created using either an existing TYPE_ID or the type inferred from the payload, and the new table name will have to meet standard table naming criteria.
        dataText - Records formatted as delimited text
        dataBytes - Records formatted as binary data
        modifyColumns - Not implemented yet. The default value is an empty Map.
        createTableOptions - Options used when creating the target table. Includes type to use. The other options match those in createTable. The default value is an empty Map.
        options - Optional parameters.
        • BAD_RECORD_TABLE_NAME: Optional name of a table to which records that were rejected are written. The bad-record-table has the following columns: line_number (long), line_rejected (string), error_message (string).
        • BAD_RECORD_TABLE_LIMIT: A positive integer indicating the maximum number of records that can be written to the bad-record-table. Default value is 10000
        • BAD_RECORD_TABLE_LIMIT_PER_INPUT: For subscriptions: A positive integer indicating the maximum number of records that can be written to the bad-record-table per file/payload. Default value will be 'bad_record_table_limit' and total size of the table per rank is limited to 'bad_record_table_limit'
        • BATCH_SIZE: Internal tuning parameter--number of records per batch when inserting data.
        • COLUMN_FORMATS: For each target column specified, applies the column-property-bound format to the source data loaded into that column. Each column format will contain a mapping of one or more of its column properties to an appropriate format for each property. Currently supported column properties include date, time, and datetime. The parameter value must be formatted as a JSON string of maps of column names to maps of column properties to their corresponding column formats, e.g., '{ "order_date" : { "date" : "%Y.%m.%d" }, "order_time" : { "time" : "%H:%M:%S" } }'. See DEFAULT_COLUMN_FORMATS for valid format syntax.
        • COLUMNS_TO_LOAD: Specifies a comma-delimited list of columns from the source data to load. If more than one file is being loaded, this list applies to all files. Column numbers can be specified discretely or as a range. For example, a value of '5,7,1..3' will insert values from the fifth column in the source data into the first column in the target table, from the seventh column in the source data into the second column in the target table, and from the first through third columns in the source data into the third through fifth columns in the target table. If the source data contains a header, column names matching the file header names may be provided instead of column numbers. If the target table doesn't exist, the table will be created with the columns in this order. If the target table does exist with columns in a different order than the source data, this list can be used to match the order of the target table. For example, a value of 'C, B, A' will create a three column table with column C, followed by column B, followed by column A; or will insert those fields in that order into a table created with columns in that order. If the target table exists, the column names must match the source data field names for a name-mapping to be successful. Mutually exclusive with COLUMNS_TO_SKIP.
        • COLUMNS_TO_SKIP: Specifies a comma-delimited list of columns from the source data to skip. Mutually exclusive with COLUMNS_TO_LOAD.
        • COMPRESSION_TYPE: Optional: payload compression type. Supported values:
          • NONE: Uncompressed
          • AUTO: Default. Auto detect compression type
          • GZIP: gzip file compression.
          • BZIP2: bzip2 file compression.
          The default value is AUTO.
        • DEFAULT_COLUMN_FORMATS: Specifies the default format to be applied to source data loaded into columns with the corresponding column property. Currently supported column properties include date, time, and datetime. This default column-property-bound format can be overridden by specifying a column property and format for a given target column in COLUMN_FORMATS. For each specified annotation, the format will apply to all columns with that annotation unless a custom COLUMN_FORMATS for that annotation is specified. The parameter value must be formatted as a JSON string that is a map of column properties to their respective column formats, e.g., '{ "date" : "%Y.%m.%d", "time" : "%H:%M:%S" }'. Column formats are specified as a string of control characters and plain text. The supported control characters are 'Y', 'm', 'd', 'H', 'M', 'S', and 's', which follow the Linux 'strptime()' specification, as well as 's', which specifies seconds and fractional seconds (though the fractional component will be truncated past milliseconds). Formats for the 'date' annotation must include the 'Y', 'm', and 'd' control characters. Formats for the 'time' annotation must include the 'H', 'M', and either 'S' or 's' (but not both) control characters. Formats for the 'datetime' annotation meet both the 'date' and 'time' control character requirements. For example, '{"datetime" : "%m/%d/%Y %H:%M:%S" }' would be used to interpret text as "05/04/2000 12:12:11"
        • ERROR_HANDLING: Specifies how errors should be handled upon insertion. Supported values:
          • PERMISSIVE: Records with missing columns are populated with nulls if possible; otherwise, the malformed records are skipped.
          • IGNORE_BAD_RECORDS: Malformed records are skipped.
          • ABORT: Stops current insertion and aborts entire operation when an error is encountered. Primary key collisions are considered abortable errors in this mode.
          The default value is ABORT.
        • FILE_TYPE: Specifies the type of the file(s) whose records will be inserted. Supported values:
          • AVRO: Avro file format
          • DELIMITED_TEXT: Delimited text file format; e.g., CSV, TSV, PSV, etc.
          • GDB: Esri/GDB file format
          • JSON: Json file format
          • PARQUET: Apache Parquet file format
          • SHAPEFILE: ShapeFile file format
          The default value is DELIMITED_TEXT.
        • FLATTEN_COLUMNS: Specifies how to handle nested columns. Supported values:
          • TRUE: Break up nested columns to multiple columns
          • FALSE: Treat nested columns as json columns instead of flattening
          The default value is FALSE.
        • GDAL_CONFIGURATION_OPTIONS: Comma separated list of gdal conf options, for the specific requests: key=value. The default value is ''.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for inserting into a table with a primary key, only used when not in upsert mode (upsert mode is disabled when UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record being inserted that is rejected for having primary key values that match those of an existing table record will be ignored with no error generated. If FALSE, the rejection of any record for having primary key values matching an existing record will result in an error being reported, as determined by ERROR_HANDLING. If the specified table does not have a primary key or if upsert mode is in effect (UPDATE_ON_EXISTING_PK is TRUE), then this option has no effect. Supported values:
          • TRUE: Ignore new records whose primary key values collide with those of existing records
          • FALSE: Treat as errors any new records whose primary key values collide with those of existing records
          The default value is FALSE.
        • INGESTION_MODE: Whether to do a full load, dry run, or perform a type inference on the source data. Supported values:
          • FULL: Run a type inference on the source data (if needed) and ingest
          • DRY_RUN: Does not load data, but walks through the source data and determines the number of valid records, taking into account the current mode of ERROR_HANDLING.
          • TYPE_INFERENCE_ONLY: Infer the type of the source data and return, without ingesting any data. The inferred type is returned in the response.
          The default value is FULL.
        • LAYER: Optional: geo files layer(s) name(s): comma separated. The default value is ''.
        • LOADING_MODE: Scheme for distributing the extraction and loading of data from the source data file(s). This option applies only when loading files that are local to the database. Supported values:
          • HEAD: The head node loads all data. All files must be available to the head node.
          • DISTRIBUTED_SHARED: The head node coordinates loading data by worker processes across all nodes from shared files available to all workers. NOTE: Instead of existing on a shared source, the files can be duplicated on a source local to each host to improve performance, though the files must appear as the same data set from the perspective of all hosts performing the load.
          • DISTRIBUTED_LOCAL: A single worker process on each node loads all files that are available to it. This option works best when each worker loads files from its own file system, to maximize performance. In order to avoid data duplication, either each worker performing the load needs to have visibility to a set of files unique to it (no file is visible to more than one node) or the target table needs to have a primary key (which will allow the worker to automatically deduplicate data). NOTE: If the target table doesn't exist, the table structure will be determined by the head node. If the head node has no files local to it, it will be unable to determine the structure and the request will fail. If the head node is configured to have no worker processes, no data strictly accessible to the head node will be loaded.
          The default value is HEAD.
        • LOCAL_TIME_OFFSET: For Avro local timestamp columns
        • MAX_RECORDS_TO_LOAD: Limit the number of records to load in this request: If this number is larger than a batch_size, then the number of records loaded will be limited to the next whole number of batch_size (per working thread). The default value is ''.
        • NUM_TASKS_PER_RANK: Optional: number of tasks for reading file per rank. Default will be external_file_reader_num_tasks
        • POLL_INTERVAL: If TRUE, the number of seconds between attempts to load external files into the table. If zero, polling will be continuous as long as data is found. If no data is found, the interval will steadily increase to a maximum of 60 seconds.
        • PRIMARY_KEYS: Optional: comma separated list of column names, to set as primary keys, when not specified in the type. The default value is ''.
        • SCHEMA_REGISTRY_CONNECTION_RETRIES: Confluent Schema registry connection timeout (in Secs)
        • SCHEMA_REGISTRY_CONNECTION_TIMEOUT: Confluent Schema registry connection timeout (in Secs)
        • SCHEMA_REGISTRY_MAX_CONSECUTIVE_CONNECTION_FAILURES: Max records to skip due to SR connection failures, before failing
        • MAX_CONSECUTIVE_INVALID_SCHEMA_FAILURE: Max records to skip due to schema related errors, before failing
        • SCHEMA_REGISTRY_SCHEMA_NAME: Name of the Avro schema in the schema registry to use when reading Avro records.
        • SHARD_KEYS: Optional: comma separated list of column names, to set as primary keys, when not specified in the type. The default value is ''.
        • SKIP_LINES: Skip a number of lines from the beginning of the file.
        • SUBSCRIBE: Continuously poll the data source to check for new data and load it into the table. Supported values: The default value is FALSE.
        • TABLE_INSERT_MODE: Optional: table_insert_mode. When inserting records from multiple files: if table_per_file then insert from each file into a new table. Currently supported only for shapefiles. Supported values: The default value is SINGLE.
        • TEXT_COMMENT_STRING: Specifies the character string that should be interpreted as a comment line prefix in the source data. All lines in the data starting with the provided string are ignored. For DELIMITED_TEXT FILE_TYPE only. The default value is '#'.
        • TEXT_DELIMITER: Specifies the character delimiting field values in the source data and field names in the header (if present). For DELIMITED_TEXT FILE_TYPE only. The default value is ','.
        • TEXT_ESCAPE_CHARACTER: Specifies the character that is used to escape other characters in the source data. An 'a', 'b', 'f', 'n', 'r', 't', or 'v' preceded by an escape character will be interpreted as the ASCII bell, backspace, form feed, line feed, carriage return, horizontal tab, and vertical tab, respectively. For example, the escape character followed by an 'n' will be interpreted as a newline within a field value. The escape character can also be used to escape the quoting character, and will be treated as an escape character whether it is within a quoted field value or not. For DELIMITED_TEXT FILE_TYPE only.
        • TEXT_HAS_HEADER: Indicates whether the source data contains a header row. For DELIMITED_TEXT FILE_TYPE only. Supported values: The default value is TRUE.
        • TEXT_HEADER_PROPERTY_DELIMITER: Specifies the delimiter for column properties in the header row (if present). Cannot be set to same value as TEXT_DELIMITER. For DELIMITED_TEXT FILE_TYPE only. The default value is '|'.
        • TEXT_NULL_STRING: Specifies the character string that should be interpreted as a null value in the source data. For DELIMITED_TEXT FILE_TYPE only. The default value is '\N'.
        • TEXT_QUOTE_CHARACTER: Specifies the character that should be interpreted as a field value quoting character in the source data. The character must appear at beginning and end of field value to take effect. Delimiters within quoted fields are treated as literals and not delimiters. Within a quoted field, two consecutive quote characters will be interpreted as a single literal quote character, effectively escaping it. To not have a quote character, specify an empty string. For DELIMITED_TEXT FILE_TYPE only. The default value is '"'.
        • TEXT_SEARCH_COLUMNS: Add 'text_search' property to internally inferenced string columns. Comma separated list of column names or '*' for all columns. To add text_search property only to string columns of minimum size, set also the option 'text_search_min_column_length'
        • TEXT_SEARCH_MIN_COLUMN_LENGTH: Set minimum column size. Used only when 'text_search_columns' has a value.
        • TRIM_SPACE: If set to TRUE, remove leading or trailing space from fields. Supported values: The default value is FALSE.
        • TRUNCATE_STRINGS: If set to TRUE, truncate string values that are longer than the column's type size. Supported values: The default value is FALSE.
        • TRUNCATE_TABLE: If set to TRUE, truncates the table specified by tableName prior to loading the file(s). Supported values: The default value is FALSE.
        • TYPE_INFERENCE_MAX_RECORDS_READ: The default value is ''.
        • TYPE_INFERENCE_MODE: optimize type inference for: Supported values:
          • ACCURACY: Scans data to get exactly-typed and sized columns for all data scanned.
          • SPEED: Scans data and picks the widest possible column types so that 'all' values will fit with minimum data scanned
          The default value is ACCURACY.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for inserting into a table with a primary key. If set to TRUE, any existing table record with primary key values that match those of a record being inserted will be replaced by that new record (the new data will be "upserted"). If set to FALSE, any existing table record with primary key values that match those of a record being inserted will remain unchanged, while the new record will be rejected and the error handled as determined by IGNORE_EXISTING_PK and ERROR_HANDLING. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Upsert new records when primary keys match existing records
          • FALSE: Reject new records when primary keys match existing records
          The default value is FALSE.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        Generates a specified number of random records and adds them to the given table. There is an optional parameter that allows the user to customize the ranges of the column values. It also allows the user to specify linear profiles for some or all columns in which case linear values are generated rather than random ones. Only individual tables are supported for this operation.

        This operation is synchronous, meaning that a response will not be returned until all random records are fully available.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

        public InsertRecordsRandomResponse insertRecordsRandom​(String tableName,
                                                       long count,

                                                throws GPUdbException
        Generates a specified number of random records and adds them to the given table. There is an optional parameter that allows the user to customize the ranges of the column values. It also allows the user to specify linear profiles for some or all columns in which case linear values are generated rather than random ones. Only individual tables are supported for this operation.

        This operation is synchronous, meaning that a response will not be returned until all random records are fully available.

        Parameters:
        tableName - Table to which random records will be added, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table, not a view.
        count - Number of records to generate.
        options - Optional parameter to pass in specifications for the randomness of the values. This map is different from the *options* parameter of most other endpoints in that it is a map of string to map of string to doubles, while most others are maps of string to string. In this map, the top level keys represent which column's parameters are being specified, while the internal keys represents which parameter is being specified. These parameters take on different meanings depending on the type of the column. Below follows a more detailed description of the map:
        • SEED: If provided, the internal random number generator will be initialized with the given value. The minimum is 0. This allows for the same set of random numbers to be generated across invocation of this endpoint in case the user wants to repeat the test. Since options, is a map of maps, we need an internal map to provide the seed value. For example, to pass 100 as the seed value through this parameter, you need something equivalent to: 'options' = {'seed': { 'value': 100 } }.
          • VALUE: The seed value to use
        • ALL: This key indicates that the specifications relayed in the internal map are to be applied to all columns of the records.
          • MIN: For numerical columns, the minimum of the generated values is set to this value. Default is -99999. For point, shape, and track columns, min for numeric 'x' and 'y' columns needs to be within [-180, 180] and [-90, 90], respectively. The default minimum possible values for these columns in such cases are -180.0 and -90.0. For the 'TIMESTAMP' column, the default minimum corresponds to Jan 1, 2010. For string columns, the minimum length of the randomly generated strings is set to this value (default is 0). If both minimum and maximum are provided, minimum must be less than or equal to max. If the min is outside the accepted ranges for strings columns and 'x' and 'y' columns for point/shape/track, then those parameters will not be set; however, an error will not be thrown in such a case. It is the responsibility of the user to use the ALL parameter judiciously.
          • MAX: For numerical columns, the maximum of the generated values is set to this value. Default is 99999. For point, shape, and track columns, max for numeric 'x' and 'y' columns needs to be within [-180, 180] and [-90, 90], respectively. The default minimum possible values for these columns in such cases are 180.0 and 90.0. For string columns, the maximum length of the randomly generated strings. If both minimum and maximum are provided, *max* must be greater than or equal to *min*. If the *max* is outside the accepted ranges for strings columns and 'x' and 'y' columns for point/shape/track, then those parameters will not be set; however, an error will not be thrown in such a case. It is the responsibility of the user to use the ALL parameter judiciously.
          • INTERVAL: If specified, generate values for all columns evenly spaced with the given interval value. If a max value is specified for a given column the data is randomly generated between min and max and decimated down to the interval. If no max is provided the data is linearly generated starting at the minimum value (instead of generating random data). For non-decimated string-type columns the interval value is ignored. Instead the values are generated following the pattern: 'attrname_creationIndex#', i.e. the column name suffixed with an underscore and a running counter (starting at 0). For string types with limited size (e.g. char4) the prefix is dropped. No nulls will be generated for nullable columns.
          • NULL_PERCENTAGE: If specified, then generate the given percentage of the count as nulls for all nullable columns. This option will be ignored for non-nullable columns. The value must be within the range [0, 1.0]. The default value is 5% (0.05).
          • CARDINALITY: If specified, limit the randomly generated values to a fixed set. Not allowed on a column with interval specified, and is not applicable to WKT or Track-specific columns. The value must be greater than 0. This option is disabled by default.
        • ATTR_NAME: Use the desired column name in place of ATTR_NAME, and set the following parameters for the column specified. This overrides any parameter set by ALL.
          • MIN: For numerical columns, the minimum of the generated values is set to this value. Default is -99999. For point, shape, and track columns, min for numeric 'x' and 'y' columns needs to be within [-180, 180] and [-90, 90], respectively. The default minimum possible values for these columns in such cases are -180.0 and -90.0. For the 'TIMESTAMP' column, the default minimum corresponds to Jan 1, 2010. For string columns, the minimum length of the randomly generated strings is set to this value (default is 0). If both minimum and maximum are provided, minimum must be less than or equal to max. If the min is outside the accepted ranges for strings columns and 'x' and 'y' columns for point/shape/track, then those parameters will not be set; however, an error will not be thrown in such a case. It is the responsibility of the user to use the ALL parameter judiciously.
          • MAX: For numerical columns, the maximum of the generated values is set to this value. Default is 99999. For point, shape, and track columns, max for numeric 'x' and 'y' columns needs to be within [-180, 180] and [-90, 90], respectively. The default minimum possible values for these columns in such cases are 180.0 and 90.0. For string columns, the maximum length of the randomly generated strings. If both minimum and maximum are provided, *max* must be greater than or equal to *min*. If the *max* is outside the accepted ranges for strings columns and 'x' and 'y' columns for point/shape/track, then those parameters will not be set; however, an error will not be thrown in such a case. It is the responsibility of the user to use the ALL parameter judiciously.
          • INTERVAL: If specified, generate values for all columns evenly spaced with the given interval value. If a max value is specified for a given column the data is randomly generated between min and max and decimated down to the interval. If no max is provided the data is linearly generated starting at the minimum value (instead of generating random data). For non-decimated string-type columns the interval value is ignored. Instead the values are generated following the pattern: 'attrname_creationIndex#', i.e. the column name suffixed with an underscore and a running counter (starting at 0). For string types with limited size (e.g. char4) the prefix is dropped. No nulls will be generated for nullable columns.
          • NULL_PERCENTAGE: If specified and if this column is nullable, then generate the given percentage of the count as nulls. This option will result in an error if the column is not nullable. The value must be within the range [0, 1.0]. The default value is 5% (0.05).
          • CARDINALITY: If specified, limit the randomly generated values to a fixed set. Not allowed on a column with interval specified, and is not applicable to WKT or Track-specific columns. The value must be greater than 0. This option is disabled by default.
        • TRACK_LENGTH: This key-map pair is only valid for track data sets (an error is thrown otherwise). No nulls would be generated for nullable columns.
          • MIN: Minimum possible length for generated series; default is 100 records per series. Must be an integral value within the range [1, 500]. If both min and max are specified, min must be less than or equal to max. The minimum allowed value is 1. The maximum allowed value is 500.
          • MAX: Maximum possible length for generated series; default is 500 records per series. Must be an integral value within the range [1, 500]. If both min and max are specified, max must be greater than or equal to min. The minimum allowed value is 1. The maximum allowed value is 500.
        The default value is an empty Map.

        Matches a directed route implied by a given set of latitude/longitude points to an existing underlying road network graph using a given solution type.

        IMPORTANT: It's highly recommended that you review the Graphs and Solvers concepts documentation, the Graph REST Tutorial, and/or some /match/graph examples before using this endpoint.

        Parameters:
        graphName - Name of the underlying geospatial graph resource to match to using samplePoints.
        samplePoints - Sample points used to match to an underlying geospatial graph. Sample points must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with: existing column names, e.g., 'table.column AS SAMPLE_X'; expressions, e.g., 'ST_MAKEPOINT(table.x, table.y) AS SAMPLE_WKTPOINT'; or constant values, e.g., '{1, 2, 10} AS SAMPLE_TRIPID'.
        solveMethod - The type of solver to use for graph matching. Supported values:
        • MARKOV_CHAIN: Matches samplePoints to the graph using the Hidden Markov Model (HMM)-based method, which conducts a range-tree closest-edge search to find the best combinations of possible road segments (NUM_SEGMENTS) for each sample point to create the best route. The route is secured one point at a time while looking ahead CHAIN_WIDTH number of points, so the prediction is corrected after each point. This solution type is the most accurate but also the most computationally intensive. Related options: NUM_SEGMENTS and CHAIN_WIDTH.
        • MATCH_OD_PAIRS: Matches samplePoints to find the most probable path between origin and destination pairs with cost constraints.
        • MATCH_SUPPLY_DEMAND: Matches samplePoints to optimize scheduling multiple supplies (trucks) with varying sizes to varying demand sites with varying capacities per depot. Related options: PARTIAL_LOADING and MAX_COMBINATIONS.
        • MATCH_BATCH_SOLVES: Matches samplePoints source and destination pairs for the shortest path solves in batch mode.
        • MATCH_LOOPS: Matches closed loops (Eulerian paths) originating and ending at each graph node within min and max hops (levels).
        • MATCH_CHARGING_STATIONS: Matches an optimal path across a number of ev-charging stations between source and target locations.
        • MATCH_SIMILARITY: Matches the intersection set(s) by computing the Jaccard similarity score between node pairs.
        • MATCH_PICKUP_DROPOFF: Matches the pickups and dropoffs by optimizing the total trip costs
        • MATCH_CLUSTERS: Matches the graph nodes with a cluster index using Louvain clustering algorithm
        • MATCH_PATTERN: Matches a pattern in the graph
        • MATCH_EMBEDDING: Creates vector node embeddings
        • MATCH_ISOCHRONE: Solves for isochrones for a set of input sources
        The default value is MARKOV_CHAIN.
        solutionTable - The name of the table used to store the results, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. This table contains a track of geospatial points for the matched portion of the graph, a track ID, and a score value. Also outputs a details table containing a trip ID (that matches the track ID), the latitude/longitude pair, the timestamp the point was recorded at, and an edge ID corresponding to the matched road segment. Must not be an existing table of the same name. The default value is ''.
        options - Additional parameters.
        • GPS_NOISE: GPS noise value (in meters) to remove redundant sample points. Use -1 to disable noise reduction. The default value accounts for 95% of point variation (+ or -5 meters). The default value is '5.0'.
        • NUM_SEGMENTS: Maximum number of potentially matching road segments for each sample point. For the MARKOV_CHAIN solver, the default is 3. The default value is '3'.
        • SEARCH_RADIUS: Maximum search radius used when snapping sample points onto potentially matching surrounding segments. The default value corresponds to approximately 100 meters. The default value is '0.001'.
        • CHAIN_WIDTH: For the MARKOV_CHAIN solver only. Length of the sample points lookahead window within the Markov kernel; the larger the number, the more accurate the solution. The default value is '9'.
        • SOURCE: Optional WKT starting point from samplePoints for the solver. The default behavior for the endpoint is to use time to determine the starting point. The default value is 'POINT NULL'.
        • DESTINATION: Optional WKT ending point from samplePoints for the solver. The default behavior for the endpoint is to use time to determine the destination point. The default value is 'POINT NULL'.
        • PARTIAL_LOADING: For the MATCH_SUPPLY_DEMAND solver only. When false (non-default), trucks do not off-load at the demand (store) side if the remainder is less than the store's need. Supported values:
          • TRUE: Partial off-loading at multiple store (demand) locations
          • FALSE: No partial off-loading allowed if supply is less than the store's demand.
          The default value is TRUE.
        • MAX_COMBINATIONS: For the MATCH_SUPPLY_DEMAND solver only. This is the cutoff for the number of generated combinations for sequencing the demand locations - can increase this up to 2M. The default value is '10000'.
        • MAX_SUPPLY_COMBINATIONS: For the MATCH_SUPPLY_DEMAND solver only. This is the cutoff for the number of generated combinations for sequencing the supply locations if/when 'permute_supplies' is true. The default value is '10000'.
        • LEFT_TURN_PENALTY: This will add an additional weight over the edges labeled as 'left turn' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • RIGHT_TURN_PENALTY: This will add an additional weight over the edges labeled as' right turn' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • INTERSECTION_PENALTY: This will add an additional weight over the edges labeled as 'intersection' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • SHARP_TURN_PENALTY: This will add an additional weight over the edges labeled as 'sharp turn' or 'u-turn' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • AGGREGATED_OUTPUT: For the MATCH_SUPPLY_DEMAND solver only. When it is true (default), each record in the output table shows a particular truck's scheduled cumulative round trip path (MULTILINESTRING) and the corresponding aggregated cost. Otherwise, each record shows a single scheduled truck route (LINESTRING) towards a particular demand location (store id) with its corresponding cost. The default value is 'true'.
        • OUTPUT_TRACKS: For the MATCH_SUPPLY_DEMAND solver only. When it is true (non-default), the output will be in tracks format for all the round trips of each truck in which the timestamps are populated directly from the edge weights starting from their originating depots. The default value is 'false'.
        • MAX_TRIP_COST: For the MATCH_SUPPLY_DEMAND and MATCH_PICKUP_DROPOFF solvers only. If this constraint is greater than zero (default) then the trucks/rides will skip traveling from one demand/pick location to another if the cost between them is greater than this number (distance or time). Zero (default) value means no check is performed. The default value is '0.0'.
        • FILTER_FOLDING_PATHS: For the MARKOV_CHAIN solver only. When true (non-default), the paths per sequence combination is checked for folding over patterns and can significantly increase the execution time depending on the chain width and the number of GPS samples. Supported values:
          • TRUE: Filter out the folded paths.
          • FALSE: Do not filter out the folded paths
          The default value is FALSE.
        • UNIT_UNLOADING_COST: For the MATCH_SUPPLY_DEMAND solver only. The unit cost per load amount to be delivered. If this value is greater than zero (default) then the additional cost of this unit load multiplied by the total dropped load will be added over to the trip cost to the demand location. The default value is '0.0'.
        • MAX_NUM_THREADS: For the MARKOV_CHAIN solver only. If specified (greater than zero), the maximum number of threads will not be greater than the specified value. It can be lower due to the memory and the number cores available. Default value of zero allows the algorithm to set the maximal number of threads within these constraints. The default value is '0'.
        • SERVICE_LIMIT: For the MATCH_SUPPLY_DEMAND solver only. If specified (greater than zero), any supply actor's total service cost (distance or time) will be limited by the specified value including multiple rounds (if set). The default value is '0.0'.
        • ENABLE_REUSE: For the MATCH_SUPPLY_DEMAND solver only. If specified (true), all supply actors can be scheduled for second rounds from their originating depots. Supported values:
          • TRUE: Allows reusing supply actors (trucks, e.g.) for scheduling again.
          • FALSE: Supply actors are scheduled only once from their depots.
          The default value is FALSE.
        • MAX_STOPS: For the MATCH_SUPPLY_DEMAND solver only. If specified (greater than zero), a supply actor (truck) can at most have this many stops (demand locations) in one round trip. Otherwise, it is unlimited. If 'enable_truck_reuse' is on, this condition will be applied separately at each round trip use of the same truck. The default value is '0'.
        • SERVICE_RADIUS: For the MATCH_SUPPLY_DEMAND and MATCH_PICKUP_DROPOFF solvers only. If specified (greater than zero), it filters the demands/picks outside this radius centered around the supply actor/ride's originating location (distance or time). The default value is '0.0'.
        • PERMUTE_SUPPLIES: For the MATCH_SUPPLY_DEMAND solver only. If specified (true), supply side actors are permuted for the demand combinations during MSDO optimization - note that this option increases optimization time significantly - use of 'max_combinations' option is recommended to prevent prohibitively long runs. Supported values:

        IMPORTANT: It's highly recommended that you review the Graphs and Solvers concepts documentation, the Graph REST Tutorial, and/or some /solve/graph examples before using this endpoint.

        Parameters:
        graphName - Name of the graph resource to solve.
        weightsOnEdges - Additional weights to apply to the edges of an existing graph. Weights must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS WEIGHTS_EDGE_ID', expressions, e.g., 'ST_LENGTH(wkt) AS WEIGHTS_VALUESPECIFIED', or constant values, e.g., '{4, 15, 2} AS WEIGHTS_VALUESPECIFIED'. Any provided weights will be added (in the case of 'WEIGHTS_VALUESPECIFIED') to or multiplied with (in the case of 'WEIGHTS_FACTORSPECIFIED') the existing weight(s). If using constant values in an identifier combination, the number of values specified must match across the combination. The default value is an empty List.
        restrictions - Additional restrictions to apply to the nodes/edges of an existing graph. Restrictions must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS RESTRICTIONS_EDGE_ID', expressions, e.g., 'column/2 AS RESTRICTIONS_VALUECOMPARED', or constant values, e.g., '{0, 0, 0, 1} AS RESTRICTIONS_ONOFFCOMPARED'. If using constant values in an identifier combination, the number of values specified must match across the combination. If remove_previous_restrictions option is set to true, any provided restrictions will replace the existing restrictions. Otherwise, any provided restrictions will be added (in the case of 'RESTRICTIONS_VALUECOMPARED') to or replaced (in the case of 'RESTRICTIONS_ONOFFCOMPARED'). The default value is an empty List.
        solverType - The type of solver to use for the graph. Supported values:
        • SHORTEST_PATH: Solves for the optimal (shortest) path based on weights and restrictions from one source to destinations nodes. Also known as the Dijkstra solver.
        • PAGE_RANK: Solves for the probability of each destination node being visited based on the links of the graph topology. Weights are not required to use this solver.
        • PROBABILITY_RANK: Solves for the transitional probability (Hidden Markov) for each node based on the weights (probability assigned over given edges).
        • CENTRALITY: Solves for the degree of a node to depict how many pairs of individuals that would have to go through the node to reach one another in the minimum number of hops. Also known as betweenness.
        • MULTIPLE_ROUTING: Solves for finding the minimum cost cumulative path for a round-trip starting from the given source and visiting each given destination node once then returning to the source. Also known as the traveling salesman problem.
        • INVERSE_SHORTEST_PATH: Solves for finding the optimal path cost for each destination node to route to the source node. Also known as inverse Dijkstra or the service man routing problem.
        • BACKHAUL_ROUTING: Solves for optimal routes that connect remote asset nodes to the fixed (backbone) asset nodes.
        • ALLPATHS: Solves for paths that would give costs between max and min solution radia - Make sure to limit by the 'max_solution_targets' option. Min cost should be >= shortest_path cost.
        • STATS_ALL: Solves for graph statistics such as graph diameter, longest pairs, vertex valences, topology numbers, average and max cluster sizes, etc.
        • CLOSENESS: Solves for the centrality closeness score per node as the sum of the inverse shortest path costs to all nodes in the graph.
        The default value is SHORTEST_PATH.
        sourceNodes - It can be one of the nodal identifiers - e.g: 'NODE_WKTPOINT' for source nodes. For BACKHAUL_ROUTING, this list depicts the fixed assets. The default value is an empty List.
        destinationNodes - It can be one of the nodal identifiers - e.g: 'NODE_WKTPOINT' for destination (target) nodes. For BACKHAUL_ROUTING, this list depicts the remote assets. The default value is an empty List.
        solutionTable - Name of the table to store the solution, in [schema_name.]table_name format, using standard name resolution rules. The default value is 'graph_solutions'.
        options - Additional parameters.
        • MAX_SOLUTION_RADIUS: For ALLPATHS, SHORTEST_PATH and INVERSE_SHORTEST_PATH solvers only. Sets the maximum solution cost radius, which ignores the destinationNodes list and instead outputs the nodes within the radius sorted by ascending cost. If set to '0.0', the setting is ignored. The default value is '0.0'.
        • MIN_SOLUTION_RADIUS: For ALLPATHS, SHORTEST_PATH and INVERSE_SHORTEST_PATH solvers only. Applicable only when MAX_SOLUTION_RADIUS is set. Sets the minimum solution cost radius, which ignores the destinationNodes list and instead outputs the nodes within the radius sorted by ascending cost. If set to '0.0', the setting is ignored. The default value is '0.0'.
        • MAX_SOLUTION_TARGETS: For ALLPATHS, SHORTEST_PATH and INVERSE_SHORTEST_PATH solvers only. Sets the maximum number of solution targets, which ignores the destinationNodes list and instead outputs no more than n number of nodes sorted by ascending cost where n is equal to the setting value. If set to 0, the setting is ignored. The default value is '1000'.
        • UNIFORM_WEIGHTS: When specified, assigns the given value to all the edges in the graph. Note that weights provided in weightsOnEdges will override this value.
        • LEFT_TURN_PENALTY: This will add an additional weight over the edges labeled as 'left turn' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • RIGHT_TURN_PENALTY: This will add an additional weight over the edges labeled as' right turn' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • INTERSECTION_PENALTY: This will add an additional weight over the edges labeled as 'intersection' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • SHARP_TURN_PENALTY: This will add an additional weight over the edges labeled as 'sharp turn' or 'u-turn' if the 'add_turn' option parameter of the createGraph was invoked at graph creation. The default value is '0.0'.
        • NUM_BEST_PATHS: For MULTIPLE_ROUTING solvers only; sets the number of shortest paths computed from each node. This is the heuristic criterion. Default value of zero allows the number to be computed automatically by the solver. The user may want to override this parameter to speed-up the solver. The default value is '0'.
        • MAX_NUM_COMBINATIONS: For MULTIPLE_ROUTING solvers only; sets the cap on the combinatorial sequences generated. If the default value of two millions is overridden to a lesser value, it can potentially speed up the solver. The default value is '2000000'.
        • OUTPUT_EDGE_PATH: If true then concatenated edge IDs will be added as the EDGE path column of the solution table for each source and target pair in shortest path solves. Supported values: The default value is FALSE.
        • OUTPUT_WKT_PATH: If true then concatenated wkt line segments will be added as the Wktroute column of the solution table for each source and target pair in shortest path solves. Supported values: The default value is TRUE.
        • SERVER_ID: Indicates which graph server(s) to send the request to. Default is to send to the server, amongst those containing the corresponding graph, that has the most computational bandwidth. For SHORTEST_PATH solver type, the input is split amongst the server containing the corresponding graph.
        • CONVERGENCE_LIMIT: For PAGE_RANK solvers only; Maximum percent relative threshold on the page rank scores of each node between consecutive iterations to satisfy convergence. Default value is 1 (one) percent. The default value is '1.0'.
        • MAX_ITERATIONS: For PAGE_RANK solvers only; Maximum number of page rank iterations for satisfying convergence. Default value is 100. The default value is '100'.
        • MAX_RUNS: For all CENTRALITY solvers only; Sets the maximum number of shortest path runs; maximum possible value is the number of nodes in the graph. Default value of 0 enables this value to be auto computed by the solver. The default value is '0'.
        • OUTPUT_CLUSTERS: For STATS_ALL solvers only; the cluster index for each node will be inserted as an additional column in the output. Supported values:
          • TRUE: An additional column 'CLUSTER' will be added for each node
          • FALSE: No extra cluster info per node will be available in the output
          The default value is FALSE.
        • SOLVE_HEURISTIC: Specify heuristic search criterion only for the geo graphs and shortest path solves towards a single target. Supported values:
          • ASTAR: Employs A-STAR heuristics to speed up the shortest path traversal
          • NONE: No heuristics are applied
          The default value is NONE.
        • ASTAR_RADIUS: For path solvers only when 'solve_heuristic' option is 'astar'. The shortest path traversal front includes nodes only within this radius (kilometers) as it moves towards the target location. The default value is '70'.
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        GPUdbException - if an error occurs during the operation.

      • updateRecordsRaw

        public UpdateRecordsResponse updateRecordsRaw​(RawUpdateRecordsRequest request)
                                       throws GPUdbException
        Runs multiple predicate-based updates in a single call. With the list of given expressions, any matching record's column values will be updated as provided in newValuesMaps. There is also an optional 'upsert' capability where if a particular predicate doesn't match any existing record, then a new record can be inserted.

        Note that this operation can only be run on an original table and not on a result view.

        This operation can update primary key values. By default only 'pure primary key' predicates are allowed when updating primary key values. If the primary key for a table is the column 'attr1', then the operation will only accept predicates of the form: "attr1 == 'foo'" if the attr1 column is being updated. For a composite primary key (e.g. columns 'attr1' and 'attr2') then this operation will only accept predicates of the form: "(attr1 == 'foo') and (attr2 == 'bar')". Meaning, all primary key columns must appear in an equality predicate in the expressions. Furthermore each 'pure primary key' predicate must be unique within a given request. These restrictions can be removed by utilizing some available options through options.

        The UPDATE_ON_EXISTING_PK option specifies the record primary key collision policy for tables with a primary key, while IGNORE_EXISTING_PK specifies the record primary key collision error-suppression policy when those collisions result in the update being rejected. Both are ignored on tables with no primary key.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:

                                               throws GPUdbException
        Runs multiple predicate-based updates in a single call. With the list of given expressions, any matching record's column values will be updated as provided in newValuesMaps. There is also an optional 'upsert' capability where if a particular predicate doesn't match any existing record, then a new record can be inserted.

        Note that this operation can only be run on an original table and not on a result view.

        This operation can update primary key values. By default only 'pure primary key' predicates are allowed when updating primary key values. If the primary key for a table is the column 'attr1', then the operation will only accept predicates of the form: "attr1 == 'foo'" if the attr1 column is being updated. For a composite primary key (e.g. columns 'attr1' and 'attr2') then this operation will only accept predicates of the form: "(attr1 == 'foo') and (attr2 == 'bar')". Meaning, all primary key columns must appear in an equality predicate in the expressions. Furthermore each 'pure primary key' predicate must be unique within a given request. These restrictions can be removed by utilizing some available options through options.

        The UPDATE_ON_EXISTING_PK option specifies the record primary key collision policy for tables with a primary key, while IGNORE_EXISTING_PK specifies the record primary key collision error-suppression policy when those collisions result in the update being rejected. Both are ignored on tables with no primary key.

        Type Parameters:
        TRequest - The type of object being added.
        Parameters:
        tableName - Name of table to be updated, in [schema_name.]table_name format, using standard name resolution rules. Must be a currently existing table and not a view.
        expressions - A list of the actual predicates, one for each update; format should follow the guidelines here.
        newValuesMaps - List of new values for the matching records. Each element is a map with (key, value) pairs where the keys are the names of the columns whose values are to be updated; the values are the new values. The number of elements in the list should match the length of expressions.
        data - An *optional* list of new binary-avro encoded records to insert, one for each update. If one of expressions does not yield a matching record to be updated, then the corresponding element from this list will be added to the table. The default value is an empty List.
        options - Optional parameters.
        • GLOBAL_EXPRESSION: An optional global expression to reduce the search space of the predicates listed in expressions. The default value is ''.
        • BYPASS_SAFETY_CHECKS: When set to TRUE, all predicates are available for primary key updates. Keep in mind that it is possible to destroy data in this case, since a single predicate may match multiple objects (potentially all of records of a table), and then updating all of those records to have the same primary key will, due to the primary key uniqueness constraints, effectively delete all but one of those updated records. Supported values: The default value is FALSE.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for updating a table with a primary key. There are two ways that a record collision can occur. The first is an "update collision", which happens when the update changes the value of the updated record's primary key, and that new primary key already exists as the primary key of another record in the table. The second is an "insert collision", which occurs when a given filter in expressions finds no records to update, and the alternate insert record given in data (or recordsToInsertStr) contains a primary key matching that of an existing record in the table. If UPDATE_ON_EXISTING_PK is set to TRUE, "update collisions" will result in the existing record collided into being removed and the record updated with values specified in newValuesMaps taking its place; "insert collisions" will result in the collided-into record being updated with the values in data / recordsToInsertStr (if given). If set to FALSE, the existing collided-into record will remain unchanged, while the update will be rejected and the error handled as determined by IGNORE_EXISTING_PK. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Overwrite the collided-into record when updating a record's primary key or inserting an alternate record causes a primary key collision between the record being updated/inserted and another existing record in the table
          • FALSE: Reject updates which cause primary key collisions between the record being updated/inserted and an existing record in the table
          The default value is FALSE.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for updating a table with a primary key, only used when primary key record collisions are rejected (UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record update that is rejected for resulting in a primary key collision with an existing table record will be ignored with no error generated. If FALSE, the rejection of any update for resulting in a primary key collision will cause an error to be reported. If the specified table does not have a primary key or if UPDATE_ON_EXISTING_PK is TRUE, then this option has no effect. Supported values:
          • TRUE: Ignore updates that result in primary key collisions with existing records
          • FALSE: Treat as errors any updates that result in primary key collisions with existing records
          The default value is FALSE.
        • UPDATE_PARTITION: Force qualifying records to be deleted and reinserted so their partition membership will be reevaluated. Supported values: The default value is FALSE.

      • updateRecords

        public <TRequest> UpdateRecordsResponse updateRecords​(TypeObjectMap<TRequest> typeObjectMap,
                                                      String tableName,
                                                      List<String> expressions,
                                                      List<Map<String,​String>> newValuesMaps,
                                                      List<TRequest> data,

                                               throws GPUdbException
        Runs multiple predicate-based updates in a single call. With the list of given expressions, any matching record's column values will be updated as provided in newValuesMaps. There is also an optional 'upsert' capability where if a particular predicate doesn't match any existing record, then a new record can be inserted.

        Note that this operation can only be run on an original table and not on a result view.

        This operation can update primary key values. By default only 'pure primary key' predicates are allowed when updating primary key values. If the primary key for a table is the column 'attr1', then the operation will only accept predicates of the form: "attr1 == 'foo'" if the attr1 column is being updated. For a composite primary key (e.g. columns 'attr1' and 'attr2') then this operation will only accept predicates of the form: "(attr1 == 'foo') and (attr2 == 'bar')". Meaning, all primary key columns must appear in an equality predicate in the expressions. Furthermore each 'pure primary key' predicate must be unique within a given request. These restrictions can be removed by utilizing some available options through options.

        The UPDATE_ON_EXISTING_PK option specifies the record primary key collision policy for tables with a primary key, while IGNORE_EXISTING_PK specifies the record primary key collision error-suppression policy when those collisions result in the update being rejected. Both are ignored on tables with no primary key.

        Type Parameters:
        TRequest - The type of object being added.
        Parameters:
        typeObjectMap - Type object map used for encoding input objects.
        tableName - Name of table to be updated, in [schema_name.]table_name format, using standard name resolution rules. Must be a currently existing table and not a view.
        expressions - A list of the actual predicates, one for each update; format should follow the guidelines here.
        newValuesMaps - List of new values for the matching records. Each element is a map with (key, value) pairs where the keys are the names of the columns whose values are to be updated; the values are the new values. The number of elements in the list should match the length of expressions.
        data - An *optional* list of new binary-avro encoded records to insert, one for each update. If one of expressions does not yield a matching record to be updated, then the corresponding element from this list will be added to the table. The default value is an empty List.
        options - Optional parameters.
        • GLOBAL_EXPRESSION: An optional global expression to reduce the search space of the predicates listed in expressions. The default value is ''.
        • BYPASS_SAFETY_CHECKS: When set to TRUE, all predicates are available for primary key updates. Keep in mind that it is possible to destroy data in this case, since a single predicate may match multiple objects (potentially all of records of a table), and then updating all of those records to have the same primary key will, due to the primary key uniqueness constraints, effectively delete all but one of those updated records. Supported values: The default value is FALSE.
        • UPDATE_ON_EXISTING_PK: Specifies the record collision policy for updating a table with a primary key. There are two ways that a record collision can occur. The first is an "update collision", which happens when the update changes the value of the updated record's primary key, and that new primary key already exists as the primary key of another record in the table. The second is an "insert collision", which occurs when a given filter in expressions finds no records to update, and the alternate insert record given in data (or recordsToInsertStr) contains a primary key matching that of an existing record in the table. If UPDATE_ON_EXISTING_PK is set to TRUE, "update collisions" will result in the existing record collided into being removed and the record updated with values specified in newValuesMaps taking its place; "insert collisions" will result in the collided-into record being updated with the values in data / recordsToInsertStr (if given). If set to FALSE, the existing collided-into record will remain unchanged, while the update will be rejected and the error handled as determined by IGNORE_EXISTING_PK. If the specified table does not have a primary key, then this option has no effect. Supported values:
          • TRUE: Overwrite the collided-into record when updating a record's primary key or inserting an alternate record causes a primary key collision between the record being updated/inserted and another existing record in the table
          • FALSE: Reject updates which cause primary key collisions between the record being updated/inserted and an existing record in the table
          The default value is FALSE.
        • IGNORE_EXISTING_PK: Specifies the record collision error-suppression policy for updating a table with a primary key, only used when primary key record collisions are rejected (UPDATE_ON_EXISTING_PK is FALSE). If set to TRUE, any record update that is rejected for resulting in a primary key collision with an existing table record will be ignored with no error generated. If FALSE, the rejection of any update for resulting in a primary key collision will cause an error to be reported. If the specified table does not have a primary key or if UPDATE_ON_EXISTING_PK is TRUE, then this option has no effect. Supported values:
          • TRUE: Ignore updates that result in primary key collisions with existing records
          • FALSE: Treat as errors any updates that result in primary key collisions with existing records
          The default value is FALSE.
        • UPDATE_PARTITION: Force qualifying records to be deleted and reinserted so their partition membership will be reevaluated. Supported values: The default value is FALSE.
        • TRUNCATE_STRINGS: If set to TRUE, any strings which are too long for their charN string fields will be truncated to fit. Supported values: The default value is FALSE.
        • USE_EXPRESSIONS_IN_NEW_VALUES_MAPS: When set to TRUE, all new values in newValuesMaps are considered as expression values. When set to FALSE, all new values in newValuesMaps are considered as constants. NOTE: When TRUE, string constants will need to be quoted to avoid being evaluated as expressions. Supported values: The default value is FALSE.
        • RECORD_ID: ID of a single record to be updated (returned in the call to insertRecords or getRecordsFromCollection).
        The default value is an empty Map.
        Returns:
        Response object containing the results of the operation.
        Throws:
        IllegalArgumentException - if typeObjectMap is not an instance of one of the following: Type, TypeObjectMap, Schema, or a Class that implements IndexedRecord
        GPUdbException - if an error occurs during the operation.

      • uploadFiles

        public UploadFilesResponse uploadFiles​(UploadFilesRequest request)
                                throws GPUdbException
        Uploads one or more files to KiFS. There are two methods for uploading files: load files in their entirety, or load files in parts. The latter is recommended for files of approximately 60 MB or larger.

        To upload files in their entirety, populate fileNames with the file names to upload into on KiFS, and their respective byte content in fileData.

        Multiple steps are involved when uploading in multiple parts. Only one file at a time can be uploaded in this manner. A user-provided UUID is utilized to tie all the upload steps together for a given file. To upload a file in multiple parts:

        1. Provide the file name in fileNames, the UUID in the MULTIPART_UPLOAD_UUID key in options, and a MULTIPART_OPERATION value of INIT.

        2. Upload one or more parts by providing the file name, the part data in fileData, the UUID, a MULTIPART_OPERATION value of UPLOAD_PART, and the part number in the MULTIPART_UPLOAD_PART_NUMBER. The part numbers must start at 1 and increase incrementally. Parts may not be uploaded out of order.

        3. Complete the upload by providing the file name, the UUID, and a MULTIPART_OPERATION value of COMPLETE.

        Multipart uploads in progress may be canceled by providing the file name, the UUID, and a MULTIPART_OPERATION value of CANCEL. If an new upload is initialized with a different UUID for an existing upload in progress, the pre-existing upload is automatically canceled in favor of the new upload.

        The multipart upload must be completed for the file to be usable in KiFS. Information about multipart uploads in progress is available in showFiles.

        File data may be pre-encoded using base64 encoding. This should be indicated using the FILE_ENCODING option, and is recommended when using JSON serialization.

        Each file path must reside in a top-level KiFS directory, i.e. one of the directories listed in showDirectories. The user must have write permission on the directory. Nested directories are permitted in file name paths. Directories are delineated with the directory separator of '/'. For example, given the file path '/a/b/c/d.txt', 'a' must be a KiFS directory.

        These characters are allowed in file name paths: letters, numbers, spaces, the path delimiter of '/', and the characters: '.' '-' ':' '[' ']' '(' ')' '#' '='.

        Parameters:
        request - Request object containing the parameters for the operation.
        Returns:
        Response object containing the results of the operation.
        Throws:

        Generate an image containing isolines for travel results using an existing graph. Isolines represent curves of equal cost, with cost typically referring to the time or distance assigned as the weights of the underlying graph. See Graphs and Solvers for more information on graphs.
        Parameters:
        graphName - Name of the graph on which the isochrone is to be computed.
        sourceNode - Starting vertex on the underlying graph from/to which the isochrones are created.
        maxSolutionRadius - Extent of the search radius around sourceNode. Set to '-1.0' for unrestricted search radius. The default value is -1.0.
        weightsOnEdges - Additional weights to apply to the edges of an existing graph. Weights must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS WEIGHTS_EDGE_ID', or expressions, e.g., 'ST_LENGTH(wkt) AS WEIGHTS_VALUESPECIFIED'. Any provided weights will be added (in the case of 'WEIGHTS_VALUESPECIFIED') to or multiplied with (in the case of 'WEIGHTS_FACTORSPECIFIED') the existing weight(s). The default value is an empty List.
        restrictions - Additional restrictions to apply to the nodes/edges of an existing graph. Restrictions must be specified using identifiers; identifiers are grouped as combinations. Identifiers can be used with existing column names, e.g., 'table.column AS RESTRICTIONS_EDGE_ID', or expressions, e.g., 'column/2 AS RESTRICTIONS_VALUECOMPARED'. If REMOVE_PREVIOUS_RESTRICTIONS is set to TRUE, any provided restrictions will replace the existing restrictions. If REMOVE_PREVIOUS_RESTRICTIONS is set to FALSE, any provided restrictions will be added (in the case of 'RESTRICTIONS_VALUECOMPARED') to or replaced (in the case of 'RESTRICTIONS_ONOFFCOMPARED'). The default value is an empty List.
        numLevels - Number of equally-separated isochrones to compute. The default value is 1.
        generateImage - If set to TRUE, generates a PNG image of the isochrones in the response. Supported values:
        • true
        • false
        The default value is true.
        levelsTable - Name of the table to output the isochrones to, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. The table will contain levels and their corresponding WKT geometry. If no value is provided, the table is not generated. The default value is ''.
        styleOptions - Various style related options of the isochrone image.
        solveOptions - Solver specific parameters.
        • REMOVE_PREVIOUS_RESTRICTIONS: Ignore the restrictions applied to the graph during the creation stage and only use the restrictions specified in this request if set to TRUE. Supported values: The default value is FALSE.
        • RESTRICTION_THRESHOLD_VALUE: Value-based restriction comparison. Any node or edge with a 'RESTRICTIONS_VALUECOMPARED' value greater than the RESTRICTION_THRESHOLD_VALUE will not be included in the solution.
        • UNIFORM_WEIGHTS: When specified, assigns the given value to all the edges in the graph. Note that weights provided in weightsOnEdges will override this value.
        The default value is an empty Map.

        • LABELS_SEARCH_WINDOW: When ADD_LABELS is set to TRUE, a search window is used to rate the local quality of each isoline. Smooth, continuous, long stretches with relatively flat angles are favored. The provided value is multiplied by the LABELS_FONT_SIZE to calculate the final window size. The default value is '4'.
        • LABELS_INTRALEVEL_SEPARATION: When ADD_LABELS is set to TRUE, this value determines the distance (in multiples of the LABELS_FONT_SIZE) to use when separating labels of different values. The default value is '4'.
