Labels: pull-request-available (was: )
> Refactor SQL_GROUPED_AGG_PANDAS_UDF
> -----------------------------------
>
> Key: SPARK-56781
> URL: https://issues.apache.org/jira/browse/SPARK-56781
> Project: Spark
> Issue Type: Sub-task
> Components: PySpark
> Affects Versions: 4.2.0
> Reporter: Yicong Huang
> Priority: Major
> Labels: pull-request-available
>
> Extract the grouped aggregation Pandas UDF logic out of
> {{ArrowStreamAggPandasUDFSerializer}} so that {{SQL_GROUPED_AGG_PANDAS_UDF}}
> is self-contained inside {{read_udfs()}} and uses {{ArrowStreamSerializer}}
> directly. The Pandas-side aggregation should be performed in the wrapper
> function rather than inside a custom serializer.
> Depends on the benchmark added in SPARK-56562. Tracked under SPARK-55388.
