             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).
