The RecordBatchReader[1] _should_ support streaming. That being said, I haven't personally used it in that way. I've been doing some JS/Rust lately but utilizing FFI and not flight. We convert each batch into a complete IPC file (in an in-memory buffer) and then just use `tableFromIPC`. We do this here[2] (in case its at all useful).
