--------------------------------
Summary: [C++][FlightRPC] Improve concurrent call implementation
in UCX client
Key: ARROW-16127
URL: https://issues.apache.org/jira/browse/ARROW-16127
Project: Apache Arrow
Issue Type: Improvement
Components: C++, FlightRPC
Reporter: David Li
This currently relies on a pool of workers and endpoints; ideally we would be
able to share a worker or even better multiplex multiple calls over a single
endpoint (this would require wire protocol changes, however!). Care should be
taken not to hurt performance if we do enable a multithreaded worker (which
would be necessary, unless we switch to a model where all threads send work to
a single worker thread).
