------------------------------------
Summary: 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
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
on constant literal.
