I have gotten my service to work with Arrow Flight, but need to enable compression.
\n
The FlightServer.Builder and FlightClient.builder constructs don't expose any API for adding compression.
\n
Is this possible? Can I get some pointers?
\n
Generative AI tools are hallucinating on this question with spurious methods to add interceptors and compression on the builders. I don't see them on the Arrow Flight API.
