------------------------------------
Summary: Inline ArrowStreamArrowUDFSerializer into
ArrowStreamAggArrowUDFSerializer
Key: SPARK-56084
URL: https://issues.apache.org/jira/browse/SPARK-56084
Project: Spark
Issue Type: Sub-task
Components: PySpark
Affects Versions: 4.2.0
Reporter: Yicong Huang
After the refactoring of {{SQL_SCALAR_ARROW_UDF}} (SPARK-55390) and
{{SQL_SCALAR_ARROW_ITER_UDF}} (SPARK-55577), {{ArrowStreamArrowUDFSerializer}}
is no longer directly instantiated. Its only remaining child class is
{{ArrowStreamAggArrowUDFSerializer}}.
Inline {{ArrowStreamArrowUDFSerializer}}'s {{__init__}} and {{dump_stream}}
into {{ArrowStreamAggArrowUDFSerializer}} (which will inherit directly from
{{ArrowStreamSerializer}}), then delete the {{ArrowStreamArrowUDFSerializer}}
class.
*Progress Tracker context*: Serializer Cleanup cell for
{{SQL_SCALAR_ARROW_UDF}} and {{SQL_SCALAR_ARROW_ITER_UDF}}.
