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

             Summary: [Flight] Allow for optional unique flight identifier to be sent with FlightGetInfo
                 Key: ARROW-3328
                 URL: https://issues.apache.org/jira/browse/ARROW-3328
             Project: Apache Arrow
          Issue Type: Improvement
          Components: FlightRPC
            Reporter: Wes McKinney
             Fix For: 0.12.0


There could either be

* A global identifier for the entire flight
* Endpoint-specific identifiers

A client could use these unique identifier to perform other kinds of actions. An example would be retrieving logs or statistics about a get -- you could see time spent writing the dataset to gRPC or time spent constructing the dataset before handing off to the gRPC write layer
