**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** When using FlightDataEncoder to send arrow batches to a flight do_put endpoint, FlightDescriptor cannot easily be set on first message. https://arrow.apache.org/docs/format/Flight.html#uploading-data **Describe the solution you'd like** On FlightDataEncoderBuilder a `with_flight_descriptor` method would be nice. The FlightDescriptor would then be set on the first FlightData retrieved from the encoder. **Describe alternatives you've considered** Here is a workaround, I may be missing something simpler ```rust let mut encoder = FlightDataEncoderBuilder::new() .with_schema(schema.clone()) .build(stream); let mut first_flight_data = encoder .next() .await .expect("no flight data") .expect("flight data was error"); first_flight_data.flight_descriptor = Some(FlightDescriptor { r#type: DescriptorType::Path.into(), path: vec!["table_name".to_string()], cmd: Bytes::default(), }); let put_stream = stream::once(async { Ok(first_flight_data) }).chain(encoder); ``` -- This is an automated message from the Apache Git Service.
