> 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 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?
