> Extract arrow_to_pandas converter logic into ArrowArrayToPandasConversion
> -------------------------------------------------------------------------
>
> Key: SPARK-55176
> URL: https://issues.apache.org/jira/browse/SPARK-55176
> Project: Spark
> Issue Type: Improvement
> Components: PySpark
> Affects Versions: 4.2.0
> Reporter: Yicong Huang
> Assignee: Yicong Huang
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.2.0

>
> Problem:
> {{ArrowStreamPandasSerializer.arrow_to_pandas}} and
> {{ArrowStreamPandasUDFSerializer.arrow_to_pandas}} mix Arrow-to-pandas
> conversion logic with serializer instance state. The conversion logic is
> duplicated and tightly coupled to serializer classes.
> Proposal:
> Extract the conversion logic into
> {{ArrowArrayToPandasConversion.create_converter}} factory method. Serializers
> can then use the factory to create converters without defining their own
> {{arrow_to_pandas}} methods.
