------------------------------------
Assignee: Ian Cook
> Add toArrow() DataFrame method to PySpark
> -----------------------------------------
>
> Key: SPARK-47365
> URL: https://issues.apache.org/jira/browse/SPARK-47365
> Project: Spark
> Issue Type: Sub-task
> Components: Connect, Input/Output, PySpark, SQL
> Affects Versions: 4.0.0, 3.5.1
> Reporter: Ian Cook
> Assignee: Ian Cook
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.0.0
>
>
> Over in the Apache Arrow community, we hear from a lot of users who want to
> return the contents of a PySpark DataFrame as a [PyArrow
> Table|https://arrow.apache.org/docs/python/generated/pyarrow.Table.html].
> Currently the only documented way to do this is:
> *PySpark DataFrame* --> *pandas DataFrame* --> *PyArrow Table*
> This adds significant overhead compared to going direct from PySpark
> DataFrame to PyArrow Table. Since [PySpark already goes through PyArrow to
> convert to
> pandas|https://spark.apache.org/docs/latest/api/python/user_guide/sql/arrow_pandas.html],
> would it be possible to publicly expose a *toArrow()* method of the Spark
> DataFrame class?
