Gengliang Wang resolved SPARK-41633.
------------------------------------
Resolution: Won't Do
> Identify aggregation expression in the nodePatterns of PythonUDF
> ----------------------------------------------------------------
>
> Key: SPARK-41633
> URL: https://issues.apache.org/jira/browse/SPARK-41633
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Gengliang Wang
> Assignee: Gengliang Wang
> Priority: Major
>
> When a PythonUDF is evaluated as SQL_GROUPED_AGG_PANDAS_UDF, we can mark it
> as AGGREGATE_EXPRESSION in the `nodePatterns`. So that we can check whether
> an expression contains aggregation with a handy way:
> `expr.containsPattern(AGGREGATE_EXPRESSION)`
