Ian Cook updated SPARK-47365:
-----------------------------
Description:
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 (possibly experimental)
*toArrowTable()* method of the Spark DataFrame class?
