Wes McKinney commented on ARROW-596:
------------------------------------
{{pyarrow.Buffer}} has a {{to_pybytes}} method as a last resort. Converting to
bytes is bad because it is a memory copy
Is there a way to do a zero-copy memory handoff to a memoryview? I can dig into
how NumPy provides a zero-copy buffer interface but in case you know off hand
the right tool to use
> [Python] Add convenience function to convert pandas.DataFrame to
> pyarrow.Buffer containing a file or stream representation
