Can Linkerd use a connectionpool with GRPC load balancing?

[janwytze]

The Python GRPC multiprocessing server example given by GRPC has a problem. Each tcp connection will be handled by 1 process, since grpc keeps the connections open all requests are handled by one process. In my case the tasks that are executed can take 10 seconds, I now have to send the tasks over different connections on the client side to make use of the multiprocessing, but I don't want the client to be responsible for the multiprocessing on the server side.

This problem is caused by how bad Python is in real multi-threading, but can it by fixed by Linkerd?

I was wondering if it is possible that the connection between the linkerd-proxy and the grpc server can work with a connection pool. This way Linkerd can distribute the incoming requests over the different connections.
