Building a System on Top of a GRCPC?

With asinc programming models and malti threading, it seems like maybe you can really decouple everything wileusin g r pc. So there's a lot different ways to go about this kind of problem. One thing you might reach for here is a pub sub service where the client instead publishes a message to a pub sub Service.

In order to find its results.
