> We should be able to provide a custom data stream as the result of Flight
> do_get in Python. In particular, when returning data produced on the fly, or
> when returning a large Pandas DataFrame, it'd be nice to provide data in
> chunks as it becomes available, rather than having to copy everything into a
> Table first.
> On the Python side, a FlightDataStream wrapper that accepts RecordBatches
> from a Python generator should suffice.
