-------------------------------
Summary: [FlightRPC][C++] Make it possible to target a specific
payload size
Key: ARROW-8487
URL: https://issues.apache.org/jira/browse/ARROW-8487
Project: Apache Arrow
Issue Type: Improvement
Components: C++, FlightRPC
Reporter: David Li
gRPC by default limits message sizes on the wire. While Flight in turn disables
these by default, they're still useful to be able to control memory
consumption. A well-behaved client/server may wish to split up writes to
respect these limits. However, right now, there's no way to measure the memory
usage of what you're about to write without serializing it.
With ARROW-5377, we can in theory avoid this by having the writer take control
of serialization, producing the IpcPayload, then measuring the size and writing
the payload if the size is as desired. However, Flight doesn't provide such a
low-level mechanism yet - we'd need to open that up as well.
