-----------------------------------
Assignee: Xianyang Liu
> Deterministic ApplyFunctionExpression should be foldable
> --------------------------------------------------------
>
> Key: SPARK-44930
> URL: https://issues.apache.org/jira/browse/SPARK-44930
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.4.1
> Reporter: Xianyang Liu
> Assignee: Xianyang Liu
> Priority: Major
>
> Currently, ApplyFunctionExpression is unfoldable because inherits the default
> value from Expression. However, it should be foldable for a deterministic
> ApplyFunctionExpression. This could help optimize the usage for V2 UDF
> applying to constant expressions.
