Holden Karau created SPARK-47031:
------------------------------------
Summary: 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
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.
