- We always do the processing asynchronously but maintain a synchronous API for the implementor of the processor. - there are a lot of string copies right now. Having a StringPiece object in grpc++ would really help with that (as we would use it for C++ metadata). - Please review the API carefully and if you're happy with it, I'll proceed with tests.pull/2933/head
