Class: GPUdb

GPUdb(url, optionsopt)

GPUdb API object that provides access to GPUdb server functions.

Constructor

new GPUdb(url, optionsopt)

Creates a GPUdb API object for the specified URL using the given options. Once created, all options are immutable; to use a different URL or change options, create a new instance. (Creating a new instance does not communicate with the server and should not cause performance concerns.)
Parameters:
Name Type Attributes Description
url String | Array.<String> The URL of the GPUdb server (e.g., http://hostname:9191). May also be specified as a list of urls; all urls in the list must be well formed.
options Object <optional>
 A set of configurable options for the GPUdb API.
Properties
Name Type Attributes Description
username String <optional>
 The username to be used for authentication to GPUdb. This username will be sent with every GPUdb request made via the API along with the specified password and may be used for authorization decisions by the server if it is so configured. If neither username nor password is specified, no authentication will be performed.
password String <optional>
 The password to be used for authentication to GPUdb. This password will be sent with every GPUdb request made via the API along with the specified username and may be used for authorization decisions by the server if it is so configured. If neither username nor password is specified, no authentication will be performed.
timeout Number <optional>
 The timeout value, in milliseconds, after which requests to GPUdb will be aborted. A timeout value of zero is interpreted as an infinite timeout. Note that timeout is not suppored for synchronous requests, which will not return until a response is received and cannot be aborted.

admin_add_host(host_address, options, callback) → {Promise}

Adds a host to an existing cluster.

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

Parameters:
Name Type Description
host_address String 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 Object Optional parameters.
  • 'dry_run': If set to true, only validation checks will be performed. No host is added. Supported values:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    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.

Type
Promise

admin_add_host_request(request, callback) → {Promise}

Adds a host to an existing cluster.

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

Parameters:
Name Type Description

Returns:
A promise that will be fulfilled with the response object, if no callback function is provided.
Type
Promise

admin_add_ranks(hosts, config_params, options, callback) → {Promise}

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 GPUdb#admin_rebalance.

The database must be offline for this operation, see GPUdb#admin_offline

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) * config_params 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 GPUdb#create_job.

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

Parameters:
Name Type Description
hosts Array.<String> 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 GPUdb#admin_add_host. 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 config_params.
config_params Array.<Object> 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 config_params 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 config_params array will result in the new ranks being set with default parameters.
options Object Optional parameters.
  • 'dry_run': If true, only validation checks will be performed. No ranks are added. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.

admin_rebalance(options, callback) → {Promise}

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 GPUdb#admin_offline

* If GPUdb#admin_rebalance 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 GPUdb#admin_rebalance 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

NOTE: Replicated data will not move as a result of this call

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 GPUdb#create_job.

Parameters:
Name Type Description
options Object 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:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    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 GPUdb#admin_verify_db 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:
    • 'true'
    • 'false'
    The default value is 'false'.

aggregate_group_by(table_name, column_names, offset, limit, options, callback) → {Promise}

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 column_names is an unrestricted-length string.

Parameters:
Name Type Description
table_name String Name of an existing table or view on which the operation will be performed, in [schema_name.]table_name format, using standard name resolution rules.
column_names Array.<String> List of one or more column names, expressions, and aggregate expressions.
offset Number A positive integer indicating the number of initial results to skip (this can be useful for paging through the results).
limit Number 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 has_more_records to see if more records exist in the result to be fetched, and offset & limit to request subsequent pages of results.
options Object 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:

  • 'strategy_definition': The tier strategy for the table and its columns.
  • 'result_table': The name of a table used to store the results, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. Column names (group-by and aggregate fields) need to be given aliases e.g. ["FChar256 as fchar256", "sum(FDouble) as sfd"]. If present, no results are returned in the response. This option is not available if one of the grouping attributes is an unrestricted string (i.e.; not charN) type.
  • 'result_table_persist': If true, then the result table specified in result_table will be persisted and will not expire unless a ttl is specified. If false, then the result table will be an in-memory table and will expire unless a ttl is specified otherwise. Supported values:

aggregate_k_means(table_name, column_names, k, tolerance, options, callback) → {Promise}

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:
Name Type Description
table_name String Name of the table on which the operation will be performed. Must be an existing table, in [schema_name.]table_name format, using standard name resolution rules.

k Number The number of mean points to be determined by the algorithm.
tolerance Number Stop iterating when the distances between successive points is less than the given tolerance.
options Object Optional parameters.
  • 'whiten': When set to 1 each of the columns is first normalized by its stdv - default is not to whiten.
  • 'max_iters': Number of times to try to hit the tolerance limit before giving up - default is 10.
  • 'num_tries': Number of times to run the k-means algorithm with a different randomly selected starting points - helps avoid local minimum. Default is 1.
  • '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.

aggregate_statistics(table_name, column_name, stats, options, callback) → {Promise}

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 column_name 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 & mean of column_name x and additional_column_names y & 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, & z values (30), and the single average value across all x, y, & z values (15.5).

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

Parameters:
Name Type Description
table_name String Name of the table on which the statistics operation will be performed, in [schema_name.]table_name format, using standard name resolution rules.
column_name String Name of the primary column for which the statistics are to be calculated.
stats String Comma separated list of the statistics to calculate, e.g. "sum,mean". Supported values:
  • 'count': Number of objects (independent of the given column(s)).
  • 'mean': Arithmetic mean (average), equivalent to sum/count.
  • '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).
  • 'max': Maximum value of the column(s).
  • 'weighted_average': Weighted arithmetic mean (using the option weight_column_name as the weighting column).
  • 'cardinality': Number of unique values in the column(s).
  • 'estimated_cardinality': Estimate (via hyperloglog technique) of the number of unique values in the column(s).
  • 'percentile': Estimate (via t-digest) of the given percentile of the column(s) (percentile(50.0) will be an approximation of the median). Add a second, comma-separated value to calculate percentile resolution, e.g., 'percentile(75,150)'

aggregate_statistics_by_range(table_name, select_expression, column_name, value_column_name, stats, start, end, interval, options, callback) → {Promise}

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.

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

Parameters:
Name Type Description
table_name String Name of the table on which the ranged-statistics operation will be performed, in [schema_name.]table_name format, using standard name resolution rules.
select_expression String For a non-empty expression statistics are calculated for those records for which the expression is true.
column_name String Name of the binning-column used to divide the set samples into bins.
value_column_name String Name of the value-column for which statistics are to be computed.
stats String A string of comma separated list of the statistics to calculate, e.g. 'sum,mean'. Available statistics: mean, stdv (standard deviation), variance, skew, kurtosis, sum.
start Number The lower bound of the binning-column.
end Number The upper bound of the binning-column.
interval Number The interval of a bin. Set members fall into bin i if the binning-column falls in the range [start+interval*i, start+interval*(i+1)).
options Object Map of optional parameters:
  • 'additional_column_names': A list of comma separated value-column names over which statistics can be accumulated along with the primary value_column.
  • 'bin_values': A list of comma separated binning-column values. Values that match the nth bin_values value are placed in the nth bin.
  • 'weight_column_name': Name of the column used as weighting column for the weighted_average statistic.
  • 'order_column_name': Name of the column used for candlestick charting techniques.

aggregate_statistics_by_range_request(request, callback) → {Promise}

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.

Type
Promise

aggregate_statistics_request(request, callback) → {Promise}

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 column_name 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 & mean of column_name x and additional_column_names y & 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, & z values (30), and the single average value across all x, y, & z values (15.5).

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

Parameters:
Name Type Description
request Object Request object containing the parameters for the operation.
callback GPUdbCallback Callback that handles the response.

aggregate_unique(table_name, column_name, offset, limit, options, callback) → {Promise}

Returns all the unique values from a particular column (specified by column_name) of a particular table or view (specified by table_name). If column_name is a numeric column, the values will be in binary_encoded_response. Otherwise if column_name is a string column, the values will be in json_encoded_response. 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. If the source table's shard key is used as the column_name, 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 if the value of column_name is an unrestricted-length string.

Parameters:
Name Type Description
table_name String Name of an existing table or view on which the operation will be performed, in [schema_name.]table_name format, using standard name resolution rules.
column_name String Name of the column or an expression containing one or more column names on which the unique function would be applied.
offset Number A positive integer indicating the number of initial results to skip (this can be useful for paging through the results).
limit Number 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 has_more_records to see if more records exist in the result to be fetched, and offset & limit to request subsequent pages of results.
options Object Optional parameters.

Append (or insert) all records from a source table (specified by source_table_name) to a particular target table (specified by table_name). The field map (specified by field_map) holds the user specified map of target table column names with their mapped source column names.
Parameters:
Name Type Description
table_name String The table name for the records to be appended, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table.
source_table_name String The source table name to get records from, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table name.
field_map Object Contains the mapping of column names from the target table (specified by table_name) as the keys, and corresponding column names or expressions (e.g., 'col_name+1') from the source table (specified by source_table_name). Must be existing column names in source table and target table, and their types must be matched. For details on using expressions, see Expressions.
options Object Optional parameters.
  • 'offset': A positive integer indicating the number of initial results to skip from source_table_name. Default is 0. The minimum allowed value is 0. The maximum allowed value is MAX_INT. The default value is '0'.
  • 'limit': A positive integer indicating the maximum number of results to be returned from source_table_name. Or END_OF_SET (-9999) to indicate that the max number of results should be returned. The default value is '-9999'.
  • 'expression': Optional filter expression to apply to the source_table_name. The default value is ''.
  • 'order_by': Comma-separated list of the columns to be sorted by from source table (specified by source_table_name), e.g., 'timestamp asc, x desc'. The order_by columns do not have to be present in field_map. The default value is ''.
  • 'update_on_existing_pk': Specifies the record collision policy for inserting source table records (specified by source_table_name) into a target table (specified by table_name) with a primary key. If set to true, any existing table record with primary key values that match those of a source table 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 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 source_table_name) into a target table (specified by table_name) 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'.
  • '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:
    • 'true'
    • 'false'
    The default value is 'false'.

create_projection(table_name, projection_name, column_names, options, callback) → {Promise}

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 GPUdb#get_records_by_column.

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.

create_table_external(table_name, filepaths, modify_columns, create_table_options, options, callback) → {Promise}

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 create_table_options, which contains many of the options from GPUdb#create_table; or defined implicitly, inferred from the source data.

Parameters:
Name Type Description
table_name String Name of the table to be created, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria.
filepaths Array.<String> 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 (|).
modify_columns Object Not implemented yet
create_table_options Object Options from GPUdb#create_table, allowing the structure of the table to be defined independently of the data source
  • 'type_id': ID of a currently registered type.
  • 'no_error_if_exists': If true, prevents an error from occurring if the table already exists and is of the given type. If a table with the same name but a different type exists, it is still an error. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'is_replicated': Affects the distribution scheme for the table's data. If true and the given table has no explicit shard key defined, the table will be replicated. If false, the table will be sharded according to the shard key specified in the given type_id, or randomly sharded, if no shard key is specified. Note that a type containing a shard key cannot be used to create a replicated table. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'foreign_keys': Semicolon-separated list of foreign keys, of the format '(source_column_name [, ...]) references target_table_name(primary_key_column_name [, ...]) [as foreign_key_name]'.
  • 'foreign_shard_key': Foreign shard key of the format 'source_column references shard_by_column from target_table(primary_key_column)'.
  • 'partition_type': Partitioning scheme to use. Supported values:
  • 'partition_keys': Comma-separated list of partition keys, which are the columns or column expressions by which records will be assigned to partitions defined by partition_definitions.
  • 'partition_definitions': Comma-separated list of partition definitions, whose format depends on the choice of partition_type. See range partitioning, interval partitioning, list partitioning, hash partitioning, or series partitioning for example formats.
  • 'is_automatic_partition': If true, a new partition will be created for values which don't fall into an existing partition. Currently, only supported for list partitions. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'ttl': Sets the TTL of the table specified in table_name.
  • 'chunk_size': Indicates the number of records per chunk to be used for this table.
  • 'is_result_table': Indicates whether the table is a memory-only table. A result table cannot contain columns with store_only or text_search data-handling or that are non-charN strings, and it will not be retained if the server is restarted. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'strategy_definition': The tier strategy for the table and its columns.
options Object 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, & 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, & datetime. This default column-property-bound format can be overridden by specifying a column property & 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'.
  • '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:
    • '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'.
  • 'gdal_configuration_options': Comma separated list of gdal conf options, for the specific requets: 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:

  • '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 GPUdb#alter_table on this table.
    • 'on_start': Refresh table on database startup and when manually requested by invoking the refresh action of GPUdb#alter_table on this table.
    The default value is 'manual'.
  • '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.

  • '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, & 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:
    • 'true'
    • 'false'
    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_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 seperated 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

  • 'truncate_strings': If set to true, truncate string values that are longer than the column's type size. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'truncate_table': If set to true, truncates the table specified by table_name prior to loading the file(s). Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'type_inference_mode': Optimize type inferencing for either speed or accuracy. Supported values:
    • 'accuracy': Scans data to get exactly-typed & 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_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 & 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

create_table_monitor(table_name, options, callback) → {Promise}

Creates a monitor that watches for a single table modification event type (insert, update, or delete) on a particular table (identified by table_name) and forwards event notifications to subscribers via ZMQ. After this call completes, subscribe to the returned topic_id 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 type_schema. The monitor will continue to run (regardless of whether or not there are any subscribers) until deactivated with GPUdb#clear_table_monitor.

create_type(type_definition, label, properties, options, callback) → {Promise}

Creates a new type describing the layout of a table. The type definition is a JSON string describing the fields (i.e. columns) of the type. Each field consists of a name and a data type. Supported data types are: double, float, int, long, string, and bytes. In addition, one or more properties can be specified for each column which customize the memory usage and query availability of that column. 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 data and store_only.

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.

Example of a type definition with some of the parameters::

{"type":"record", "name":"point", "fields":[{"name":"msg_id","type":"string"}, {"name":"x","type":"double"}, {"name":"y","type":"double"}, {"name":"TIMESTAMP","type":"double"}, {"name":"source","type":"string"}, {"name":"group_id","type":"string"}, {"name":"OBJECT_ID","type":"string"}] }

Properties::

{"group_id":["store_only"], "msg_id":["store_only","text_search"] }

Parameters:
Name Type Description
type_definition String a JSON string describing the columns of the type to be registered.
label String A user-defined description string which can be used to differentiate between tables and types with otherwise identical schemas.
properties Object 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. Can be set independently of data and store_only.
  • 'store_only': Persist the column value but do not make it available to queries (e.g. GPUdb#filter)-i.e. it is mutually exclusive to the data property. Any 'bytes' type column must have a store_only property. This property reduces system memory usage.
  • 'disk_optimized': Works in conjunction with the data property for string columns. This property reduces system disk usage by disabling reverse string lookups. Queries like GPUdb#filter, GPUdb#filter_by_list, and GPUdb#filter_by_value work as usual but GPUdb#aggregate_unique and GPUdb#aggregate_group_by are not allowed on columns with this property.
  • '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.
  • '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.
  • '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 type_definition. 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.
  • '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.
The default value is an empty dict ( {} ).
options Object Optional parameters.

Returns:
A promise that will be fulfilled with the response object, if no callback function is provided.
Type
Promise

create_type_request(request, callback) → {Promise}

Creates a new type describing the layout of a table. The type definition is a JSON string describing the fields (i.e. columns) of the type. Each field consists of a name and a data type. Supported data types are: double, float, int, long, string, and bytes. In addition, one or more properties can be specified for each column which customize the memory usage and query availability of that column. 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 data and store_only.

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.

Example of a type definition with some of the parameters::

{"type":"record", "name":"point", "fields":[{"name":"msg_id","type":"string"}, {"name":"x","type":"double"}, {"name":"y","type":"double"}, {"name":"TIMESTAMP","type":"double"}, {"name":"source","type":"string"}, {"name":"group_id","type":"string"}, {"name":"OBJECT_ID","type":"string"}] }

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'.

  • '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:
    • 'true'

export_records_to_files(table_name, filepath, options, callback) → {Promise}

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 GPUdb#create_datasink.

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:
Name Type Description
table_name String
filepath String 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 Object 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, & 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 GPUdb#create_datasink.
  • 'default_column_formats': Specifies the default format to use to write data. Currently supported column properties include date, time, & datetime. This default column-property-bound format can be overridden by specifying a column property & 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'.

  • '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:
    • 'uncompressed'
    • 'snappy'
    • 'gzip'
  • '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:
    • 'true'
    • 'false'
    • 'overwrite'
    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:

filter_by_series(table_name, view_name, track_id, target_track_ids, options, callback) → {Promise}

Filters objects matching all points of the given track (works only on track type data). It allows users to specify a particular track to find all other points in the table that fall within specified ranges (spatial and temporal) of all points of the given track.

The filtered points are stored in a newly created result set. The return value of the function is the number of points in the resultant set (view).

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

filter_by_string(table_name, view_name, expression, mode, column_names, options, callback) → {Promise}

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:
Name Type Description
table_name String 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.
view_name String 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.
expression String The expression with which to filter the table.
mode String 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 column_names; 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.
column_names Array.<String> List of columns on which to apply the filter. Ignored for search mode.
options Object 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 view_name. 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 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 view_name 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.

get_records_by_column(table_name, column_names, offset, limit, options, callback) → {Promise}

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 GPUdb#create_projection.

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 table_name 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:
Name Type Description
table_name String 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.
column_names Array.<String> The list of column values to retrieve.
offset Number A positive integer indicating the number of initial results to skip (this can be useful for paging through the results).
limit Number 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 has_more_records to see if more records exist in the result to be fetched, and offset & limit to request subsequent pages of results.
options Object
  • 'expression': Optional filter expression to apply to the table.
  • 'sort_by': Optional column that the data should be sorted by. Used in conjunction with sort_order. The order_by option can be used in lieu of sort_by / sort_order. The default value is ''.
  • 'sort_order': String indicating how the returned values should be sorted - ascending or descending. If sort_order is provided, sort_by has to be provided. Supported values:
    • 'ascending'
    • 'descending'
    The default value is 'ascending'.
  • 'order_by': Comma-separated list of the columns to be sorted by as well as the sort direction, e.g., 'timestamp asc, x desc'. The default value is ''.
  • 'convert_wkts_to_wkbs': If true, then WKT string columns will be returned as WKB bytes. Supported values:
    • 'true'
    • 'false'

insert_records(table_name, data, options, callback) → {Promise}

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.

Parameters:
Name Type Description
table_name String 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 Array.<Object> An array of JSON encoded data for the records to be added. All records must be of the same type as that of the table. Empty array if list_encoding is binary.
options Object 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, & 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 & 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'.
  • 'return_record_ids': If true then return the internal record id along for each inserted record. Supported values:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'dry_run': If set to true, no data will be saved and any errors will be returned. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.

Type
Promise

insert_records_from_files(table_name, filepaths, modify_columns, create_table_options, options, callback) → {Promise}

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:
Name Type Description
table_name String 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 Array.<String> 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 (|).
modify_columns Object Not implemented yet
create_table_options Object Options from GPUdb#create_table, allowing the structure of the table to be defined independently of the data source, when creating the target table
  • 'type_id': ID of a currently registered type.
  • 'no_error_if_exists': If true, prevents an error from occurring if the table already exists and is of the given type. If a table with the same name but a different type exists, it is still an error. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'is_replicated': Affects the distribution scheme for the table's data. If true and the given table has no explicit shard key defined, the table will be replicated. If false, the table will be sharded according to the shard key specified in the given type_id, or randomly sharded, if no shard key is specified. Note that a type containing a shard key cannot be used to create a replicated table. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'foreign_keys': Semicolon-separated list of foreign keys, of the format '(source_column_name [, ...]) references target_table_name(primary_key_column_name [, ...]) [as foreign_key_name]'.
  • 'foreign_shard_key': Foreign shard key of the format 'source_column references shard_by_column from target_table(primary_key_column)'.
  • 'partition_type': Partitioning scheme to use. Supported values:
  • 'partition_keys': Comma-separated list of partition keys, which are the columns or column expressions by which records will be assigned to partitions defined by partition_definitions.
  • 'partition_definitions': Comma-separated list of partition definitions, whose format depends on the choice of partition_type. See range partitioning, interval partitioning, list partitioning, hash partitioning, or series partitioning for example formats.
  • 'is_automatic_partition': If true, a new partition will be created for values which don't fall into an existing partition. Currently, only supported for list partitions. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'ttl': Sets the TTL of the table specified in table_name.
  • 'chunk_size': Indicates the number of records per chunk to be used for this table.
  • 'is_result_table': Indicates whether the table is a memory-only table. A result table cannot contain columns with store_only or text_search data-handling or that are non-charN strings, and it will not be retained if the server is restarted. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'strategy_definition': The tier strategy for the table and its columns.
options Object 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, & 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, & datetime. This default column-property-bound format can be overridden by specifying a column property & 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'.
  • 'gdal_configuration_options': Comma separated list of gdal conf options, for the specific requets: 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:
    • 'earliest'
    • 'latest'
    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:
    • 'true'
    • 'false'
    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).

    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, & 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:
    • 'true'
    • 'false'
    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 seperated 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.
  • 'truncate_strings': If set to true, truncate string values that are longer than the column's type size. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'truncate_table': If set to true, truncates the table specified by table_name prior to loading the file(s). Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'type_inference_mode': Optimize type inferencing for either speed or accuracy. Supported values:
    • 'accuracy': Scans data to get exactly-typed & 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'.
  • '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 & 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'.
callback GPUdbCallback Callback that handles the response.
Source:
Returns:
A promise that will be fulfilled with the response object, if no callback function is provided.
Type
Promise

insert_records_from_files_request(request, callback) → {Promise}

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:
Name Type Description
request Object Request object containing the parameters for the operation.
callback GPUdbCallback Callback that handles the response.

  • '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, & 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:

    • '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, & datetime. This default column-property-bound format can be overridden by specifying a column property & 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.

  • '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:

    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:

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 ''.

insert_records_random(table_name, count, options, callback) → {Promise}

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:
Name Type Description
table_name String 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 Number of records to generate.
options Object 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. Value needs to be within [0, 200]. 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 is set to this value (default is 200). If both minimum and maximum are provided, *max* must be greater than or equal to *min*. Value needs to be within [0, 200]. 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 linerally 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 (eg 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. Value needs to be within [0, 200]. 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 is set to this value (default is 200). If both minimum and maximum are provided, *max* must be greater than or equal to *min*. Value needs to be within [0, 200]. 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 linerally 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 (eg 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.
    • '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.

insert_symbol(symbol_id, symbol_format, symbol_data, options, callback) → {Promise}

Adds a symbol or icon (i.e. an image) to represent data points when data is rendered visually. Users must provide the symbol identifier (string), a format (currently supported: 'svg' and 'svg_path'), the data for the symbol, and any additional optional parameter (e.g. color). To have a symbol used for rendering create a table with a string column named 'SYMBOLCODE' (along with 'x' or 'y' for example). Then when the table is rendered (via WMS) if the 'dosymbology' parameter is 'true' then the value of the 'SYMBOLCODE' column is used to pick the symbol displayed for each point.
Parameters:

symbol_id String The id of the symbol being added. This is the same id that should be in the 'SYMBOLCODE' column for objects using this symbol
symbol_format String Specifies the symbol format. Must be either 'svg' or 'svg_path'. Supported values:
  • 'svg'
  • 'svg_path'
symbol_data String The actual symbol data. If symbol_format is 'svg' then this should be the raw bytes representing an svg file. If symbol_format is svg path then this should be an svg path string, for example: 'M25.979,12.896,5.979,12.896,5.979,19.562,25.979,19.562z'
options Object Optional parameters.
  • 'color': If symbol_format is 'svg' this is ignored. If symbol_format is 'svg_path' then this option specifies the color (in RRGGBB hex format) of the path. For example, to have the path rendered in red, used 'FF0000'. If 'color' is not provided then '00FF00' (i.e. green) is used by default.

match_graph(graph_name, sample_points, solve_method, solution_table, options, callback) → {Promise}

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 Network Graphs & Solvers concepts documentation, the Graph REST Tutorial, and/or some /match/graph examples before using this endpoint.
Parameters:
Name Type Description
graph_name String Name of the underlying geospatial graph resource to match to using sample_points.
sample_points Array.<String> 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'.
solve_method String The type of solver to use for graph matching. Supported values:
  • 'markov_chain': Matches sample_points 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 sample_points to find the most probable path between origin and destination pairs with cost constraints.
  • 'match_supply_demand': Matches sample_points 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 sample_points 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
The default value is 'markov_chain'.
solution_table String 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.
options Object 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 sample_points 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 sample_points 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 additonal weight over the edges labelled as 'left turn' if the 'add_turn' option parameter of the GPUdb#create_graph was invoked at graph creation. The default value is '0.0'.
  • 'right_turn_penalty': This will add an additonal weight over the edges labelled as' right turn' if the 'add_turn' option parameter of the GPUdb#create_graph was invoked at graph creation. The default value is '0.0'.
  • 'intersection_penalty': This will add an additonal weight over the edges labelled as 'intersection' if the 'add_turn' option parameter of the GPUdb#create_graph was invoked at graph creation. The default value is '0.0'.
  • 'sharp_turn_penalty': This will add an additonal weight over the edges labelled as 'sharp turn' or 'u-turn' if the 'add_turn' option parameter of the GPUdb#create_graph 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 travelling from one demand/pick location to another if the cost between them is greater than this number (distance or time).

  • '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 shoudl 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'.

destination_nodes Array.<String> 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.
solution_table String Name of the table to store the solution, in [schema_name.]table_name format, using standard name resolution rules.
options Object Additional parameters
  • 'max_solution_radius': For ALLPATHS, SHORTEST_PATH and INVERSE_SHORTEST_PATH solvers only.

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 destination_nodes 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 weights_on_edges will override this value.

update_records(table_name, expressions, new_values_maps, data, options, callback) → {Promise}

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 new_values_maps. 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:
Name Type Description
table_name String 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 Array.<String> A list of the actual predicates, one for each update; format should follow the guidelines here.
new_values_maps Array.<Object> 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 Array.<Object> An optional list of JSON encoded objects to insert, one for each update, to be added if the particular update did not match any objects.
options Object 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:
    • 'true'
    • 'false'
    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 records_to_insert (or records_to_insert_str) 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 new_values_maps taking its place; "insert collisions" will result in the collided-into record being updated with the values in records_to_insert/records_to_insert_str (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:
    • 'true'
    • 'false'
    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:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'use_expressions_in_new_values_maps': When set to true, all new values in new_values_maps are considered as expression values. When set to false, all new values in new_values_maps are considered as constants. NOTE: When true, string constants will need to be quoted to avoid being evaluated as expressions. Supported values:
    • 'true'
    • 'false'
    The default value is 'false'.
  • 'record_id': ID of a single record to be updated (returned in the call to GPUdb#insert_records or GPUdb#get_records_from_collection).

upload_files(file_names, file_data, options, callback) → {Promise}

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 recommeded for files of approximately 60 MB or larger.

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

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 file_names, 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 file_data, 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 GPUdb#show_files.

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 GPUdb#show_directories. The user must have write permission on the directory. Nested directories are permitted in file name paths. Directories are deliniated 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:
Name Type Description

Type
Promise

upload_files_request(request, callback) → {Promise}

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 recommeded for files of approximately 60 MB or larger.

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

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 file_names, 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 file_data, 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 GPUdb#show_files.

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 GPUdb#show_directories. The user must have write permission on the directory. Nested directories are permitted in file name paths. Directories are deliniated 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: '.' '-' ':' '[' ']' '(' ')' '#' '='.
