Introduction to Flink SQL
DWS-connector can connect to GaussDB(DWS) tables as a source table, result table, and dimension table for Flink jobs by implementing the DynamicTableSourceFactory and DynamicTableSinkFactory interfaces.
When used as the source table, DWS-Connector can push down limit and where conditions to the database for execution by implementing the SupportsLimitPushDown and SupportsFilterPushDown interfaces.
For details, see Source Table and Dimension Table.
