--------------------------------
Summary: Add toArrow() DataFrame method
Key: SPARK-47365
URL: https://issues.apache.org/jira/browse/SPARK-47365
Project: Spark
Issue Type: Improvement
Components: Input/Output, PySpark
Affects Versions: 3.5.1
Reporter: Ian Cook
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?
