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.
