[jira] [Created] (ARROW-12517) [Go] Expose App Metadata in Flight client

Paul Whalen created ARROW-12517:
-----------------------------------

             Summary: [Go] Expose App Metadata in Flight client
                 Key: ARROW-12517
                 URL: https://issues.apache.org/jira/browse/ARROW-12517
             Project: Apache Arrow
          Issue Type: Improvement
          Components: FlightRPC, Go
            Reporter: Paul Whalen


There isn't a convenient way to access the App Metadata from a Flight stream via the Go client, because the `ipc.Reader` returned from calling `flight.NewRecordReader()` only exposes the `array.Record` as you read data from it.  This should expose a Flight-specific reader so the client can also access the metadata, perhaps.

Modified `record_batch_reader.go` workaround/idea [here|https://gist.github.com/pgwhalen/ed768e18917610b2de7942144068f205].
