Basically, I have a grpc service that on a request goes and pulls some proto objects from a database instance, and sends them to a client.
In the database, the objects are actually just stored as a byte[], which comes from the proto objects .toByteArray() call.

Right now I pull the bytes from the database, deserialize them and then send them to the response observer via onNext(). I know the onNext call just serializes them again to send them off.

I was wondering it's possible for me to avoid this duplicate effort of serializing/deserializing and just give the byte[] directly to the response observer?
