Server to client inverted rpc calls

[Andrey Avtomonov]

Hi,

I'm interested in a workflow where client would connect to a server and server would call methods on a client (inverted communication).

I followed an old discussion about a server-to-server communication:

https://groups.google.com/g/grpc-io/c/Hfl-YotN5wg

I also checked a Java based POC implementation.

I was wondering if there are any python client implementations that exist?

I'm not familiar with third-party solutions in this space, but I don't believe there's a better answer today for reverse-tunneling with gRPC alone. The tracking issue for the work is here: https://github.com/grpc/grpc/issues/14101. You can manually wire this sort of thing up using BiDi streams, but it may not be terribly ergonomic.
