Wes McKinney commented on ARROW-4419:
-------------------------------------
It might be useful to write an ultra-minimal pure Python Flight server and
client (using the generated Python grpc bindings) so that we can more easily
test this kind of thing
e.g. see
https://github.com/apache/arrow/blob/master/java/flight/README.md#python-example-usage
> [Flight] Deal with body buffers in FlightData
> ---------------------------------------------

> Key: ARROW-4419
> URL: https://issues.apache.org/jira/browse/ARROW-4419
> Project: Apache Arrow
> Issue Type: Improvement
> Components: FlightRPC

> The Java implementation will fail to decode a schema message if the message
> also contains (empty) body buffers (see ArrowMessage.asSchema's precondition
> checks). However, clients using default Protobuf serialization will likely
> write an empty body buffer by default.
