Class AggregateGroupByRequest

  • All Implemented Interfaces:
    org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord
    public class AggregateGroupByRequest
extends Object
implements org.apache.avro.generic.IndexedRecord
    A set of parameters for GPUdb.aggregateGroupBy.

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

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

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

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

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

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

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

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

    Available grouping functions are Rollup, Cube, and Grouping Sets

    This service also provides support for Pivot operations.

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

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

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

        Constructs an AggregateGroupByRequest object with the specified parameters.
        Parameters:
        tableName - 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.
        columnNames - List of one or more column names, expressions, and aggregate expressions.
        offset - A positive integer indicating the number of initial results to skip (this can be useful for paging through the results). The default value is 0. The minimum allowed value is 0. The maximum allowed value is MAX_INT.

        • EXPRESSION: Filter expression to apply to the table prior to computing the aggregate group by.
        • PIPELINED_EXPRESSION_EVALUATION: evaluate the group-by during last JoinedSet filter plan step. Supported values: The default value is FALSE.
        • HAVING: Filter expression to apply to the aggregated results.
        • SORT_ORDER: [DEPRECATED--use order_by instead] String indicating how the returned values should be sorted - ascending or descending. Supported values:
          • ASCENDING: Indicates that the returned values should be sorted in ascending order.
          • DESCENDING: Indicates that the returned values should be sorted in descending order.
          The default value is ASCENDING.
        • SORT_BY: [DEPRECATED--use order_by instead] String determining how the results are sorted. Supported values:
          • KEY: Indicates that the returned values should be sorted by key, which corresponds to the grouping columns. If you have multiple grouping columns (and are sorting by key), it will first sort the first grouping column, then the second grouping column, etc.
          • VALUE: Indicates that the returned values should be sorted by value, which corresponds to the aggregates. If you have multiple aggregates (and are sorting by value), it will first sort by the first aggregate, then the second aggregate, etc.
          The default value is VALUE.
        • 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 ''.
        • STRATEGY_DEFINITION: The tier strategy for the table and its columns.
        • COMPRESSION_CODEC: The default compression codec for the result table's 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: The default value is FALSE.
        • RESULT_TABLE_FORCE_REPLICATED: Force the result table to be replicated (ignores any sharding). Must be used in combination with the RESULT_TABLE option. Supported values: The default value is FALSE.
        • RESULT_TABLE_GENERATE_PK: If TRUE then set a primary key for the result table. Must be used in combination with the RESULT_TABLE option. Supported values: The default value is FALSE.
        • RESULT_TABLE_GENERATE_SOFT_PK: If TRUE then set a soft primary key for the result table. Must be used in combination with the RESULT_TABLE option. Supported values: The default value is FALSE.
        • TTL: Sets the TTL of the table specified in RESULT_TABLE.
        • CHUNK_SIZE: Indicates the number of records per chunk to be used for the result table. Must be used in combination with the RESULT_TABLE option.
        • CHUNK_COLUMN_MAX_MEMORY: Indicates the target maximum data size for each column in a chunk to be used for the result table. Must be used in combination with the RESULT_TABLE option.
        • CHUNK_MAX_MEMORY: Indicates the target maximum data size for all columns in a chunk to be used for the result table. Must be used in combination with the RESULT_TABLE option.
        • CREATE_INDEXES: Comma-separated list of columns on which to create indexes on the result table. Must be used in combination with the RESULT_TABLE option.
        • VIEW_ID: ID of view of which the result table will be a member. The default value is ''.
        • PIVOT: pivot column
        • PIVOT_VALUES: The value list provided will become the column headers in the output. Should be the values from the pivot_column.
        • GROUPING_SETS: Customize the grouping attribute sets to compute the aggregates. These sets can include ROLLUP or CUBE operators. The attribute sets should be enclosed in parentheses and can include composite attributes. All attributes specified in the grouping sets must present in the group-by attributes.
        • ROLLUP: This option is used to specify the multilevel aggregates.
        • CUBE: This option is used to specify the multidimensional aggregates.
        • SHARD_KEY: Comma-separated list of the columns to be sharded on; e.g. 'column1, column2'. The columns specified must be present in columnNames. If any alias is given for any column name, the alias must be used, rather than the original column name. The default value is ''.
        The default value is an empty Map.
        Parameters:
        options - The new value for options.
        Returns:
        this to mimic the builder pattern.
