[jira] [Created] (SPARK-55347) Pass Generated Column as Expression to DSV2

Szehon Ho created SPARK-55347:
---------------------------------

             Summary: Pass Generated Column as Expression to DSV2
                 Key: SPARK-55347
                 URL: https://issues.apache.org/jira/browse/SPARK-55347
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 4.1.1
            Reporter: Szehon Ho


It'd be nice to pass Generated Column expression as a DSV2 Expression in DSV2 data source connector, similar to how we do it for Default Values and Check Constraint expressions.  This would allow more standards and a cleaner abstraction, as currently they are passed only as spark-dialect sql strings that the connector needs to parse using Spark catalyst.
