             Summary: Consolidate serde for SQL_GROUPED_AGG_ARROW
                 Key: SPARK-54438
                 URL: https://issues.apache.org/jira/browse/SPARK-54438
             Project: Spark
          Issue Type: Task
          Components: PySpark
    Affects Versions: 4.2.0
            Reporter: Yicong Huang


We recently added `Iterator[pandas.DataFrame]` API in `groupBy().applyInPandas()`. Which introduced a new `GroupPandasIterUDFSerializer`. We should merge this GroupPandasIterUDFSerializer with GroupPandasUDFSerializer.
