Subject Re: Is there a `write_record_batch` method corresonding to `pa.ipc.read_record_batch`?

Hi Shawn,
This method exists in the C++ implementation [1], so it is likely
reasonable to expose some form in python (I couldn't find it either in
pyarrow).  This should be reasonable straight-forward (you could follow the
path taken for read implementation) if it is something you wanted to
