ASF GitHub Bot updated ARROW-4858:
----------------------------------
Labels: flight pull-request-available (was: flight)
> [Flight][Python] Enable custom FlightDataStream in Python
> ---------------------------------------------------------
>
> Key: ARROW-4858
> URL: https://issues.apache.org/jira/browse/ARROW-4858
> Project: Apache Arrow
> Issue Type: Improvement
> Components: FlightRPC, Python
> Reporter: David Li
> Assignee: David Li
> Priority: Minor
> Labels: flight, pull-request-available
> Fix For: 0.14.0
>
>
> 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.
