Changelog

4.0.1

Bug Fixes

• DatabricksSubmitRunOperator to support taskflow (#29840)

4.0.0

Breaking changes

The DatabricksSqlHook is now conforming to the same semantics as all the other DBApiHook implementations and returns the same kind of response in its run method. Previously (pre 4.* versions of the provider, the Hook returned Tuple of (“cursor description”, “results”) which was not compatible with other DBApiHooks that return just “results”. After this change (and dependency on common.sql >= 1.3.1), The DatabricksSqlHook returns now “results” only. The description can be retrieved via last_description field of the hook after run method completes.

That makes the DatabricksSqlHook suitable for generic SQL operator and detailed lineage analysis.

If you had custom hooks or used the Hook in your TaskFlow code or custom operators that relied on this behaviour, you need to adapt your DAGs.

The Databricks DatabricksSQLOperator is also more standard and derives from common SQLExecuteQueryOperator and uses more consistent approach to process output when SQL queries are run. However in this case the result returned by execute method is unchanged (it still returns Tuple of (“description”, “results”) and this Tuple is pushed to XCom, so your DAGs relying on this behaviour should continue working without any change.
