-----------------------------------
Labels: pull-request-available (was: )
> Union of with non-determinstic expression should be non-deterministic
> ---------------------------------------------------------------------
>
> Key: SPARK-47031
> URL: https://issues.apache.org/jira/browse/SPARK-47031
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.5.0
> Reporter: Holden Karau
> Priority: Trivial
> Labels: pull-request-available
>
> We have special case handling for nullability already where any expression
> which is unioned with a nullable field becomes nullable, but we should do the
> same for deterministic.
>
> I found this while I was poking around with push downs.
>
> I believe the code to be updated would be output in the union case class.
