> 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].
