Hi, I'm using protocol buffers to retain metadata, and I would like to store the Arrow Schema in the protobuf as Arrow is doing in Flight. Looking at the Flight perf.proto, I can do the same and define a bytes field in my proto. From pyarrow, can I serialize/deserialize pyarrow.schema? I've only found pyarrow.schema.serialize() in python/arrow/types.pxi.
Thanks,
