------------------------------------

             Summary: [C++][Flight] See if reading/writing to gRPC get/put streams asynchronously helps performance
                 Key: ARROW-10351
                 URL: https://issues.apache.org/jira/browse/ARROW-10351
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Wes McKinney


We don't use any asynchronous concepts in the way that Flight is implemented now, i.e. IPC deconstruction/reconstruction (which may include compression!) is not performed concurrent with moving FlightData objects through the gRPC machinery, which may yield suboptimal performance. 

It might be better to apply an actor-type approach where a dedicated thread retrieves and prepares the next raw IPC message (within a Future) while the current IPC message is being processed -- that way reading/writing to/from the gRPC stream is not blocked on the IPC code doing its thing.
