How to easily experiment with different server implementations

[thefallentree]

Hello, right now golang grpc starts a go-routine on every single request, as seen here:

grpc-go/server.go

Line 917 in 15739b5

wg.Add(1)

I want to experiment on some ideas like "use a go worker pool and an channel to propagate back pressure to client " Which looks like it requires a new Server struct implementation. But due to Server is a concrete struct, there is no way for me to provide a override Server implementation easily without modifying the grpc source code. I can't just copy server.go either, because it is using some "internal" packages .

what's my best options here?

If you're interested in contributing improvements to our server implementation, let us know. Otherwise, what you describe could only be achieved when/if we implement this pending gRFC: grpc/proposal#103
