[jira] [Created] (SPARK-57903) Benchmark SQL_TRANSFORM_WITH_STATE_PYTHON_ROW_UDF

Yicong Huang created SPARK-57903:
------------------------------------

             Summary: Benchmark SQL_TRANSFORM_WITH_STATE_PYTHON_ROW_UDF
                 Key: SPARK-57903
                 URL: https://issues.apache.org/jira/browse/SPARK-57903
             Project: Spark
          Issue Type: Sub-task
          Components: PySpark
    Affects Versions: 4.3.0
            Reporter: Yicong Huang


Add an ASV microbenchmark for the SQL_TRANSFORM_WITH_STATE_PYTHON_ROW_UDF eval type, mirroring the existing SQL_TRANSFORM_WITH_STATE_PANDAS_UDF benchmark (SPARK-57020). This measures the stateful streaming transformation path that uses PySpark Row objects (TransformWithStateInPySparkRowSerializer), to guard against regressions in the upcoming serializer refactor.
