parsing from upstream whenever it becomes available

> Key: ARROW-3201
> URL: https://issues.apache.org/jira/browse/ARROW-3201
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, FlightRPC
> Reporter: Wes McKinney
> Priority: Major
> Labels: flight
>
> This has been discussed for a couple of years now; perhaps with Abseil this could happen at some point:
> https://github.com/protocolbuffers/protobuf/issues/1896
> Using zero-copy proto parsing (which is standard practice inside Google, but not available in open source protocol buffers) would obviate the need for the zero-copy workaround that I'm going to implement for C++ Flight RPCs
