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.
