I've found the deserialize in pa.ipc.read_schema(). From schema.serialize, I get a pyarrow Buffer. Do I need to write this to a BufferOutputStream to get raw bytes (e.g. sink.getvalue())? In Flight, I see this is casted to std:string https://github.com/apache/arrow/blob/69d595ae4c61902b3f2778e536fca6675350c88c/cpp/src/arrow/flight/internal.cc#L219 for the protbuf.
