7.23. TPCDS Connector

    This connector can also be used to test the capabilities and query syntax of Presto without configuring access to an external data source. When you query a TPCDS schema, the connector generates the data on the fly using a deterministic algorithm.

    TPCDS Schemas

    The TPCDS connector supplies several schemas:

    Every TPCDS schema provides the same set of tables. Some tables are identical in all schemas. The scale factor of the tables in a particular schema is determined from the schema name. For example, the schema sf1 corresponds to scale factor and the schema sf300 corresponds to scale factor 300. Every unit in the scale factor corresponds to a gigabyte of data. For example, for scale factor , a total of 300 gigabytes will be generated. The tiny schema is an alias for scale factor , which is a very small data set useful for testing.
