When i code GRPC Interceptors, I don't know how to put the data stored in the Redis returned to the caller. i am suddenly enlightened ,the idea from your code can solve this question better , thank you.

Thank you for writing this message, it really made my day! :)

This code was written as part of research during my PhD, and the open access paper that explains how it works is here: https://arxiv.org/pdf/2104.02463.pdf

The real intelligence comes from https://github.com/llarsson/grpc-caching-interceptors/

Since I wanted it all to work without modifying the application's code (which is of course not what you necessarily need in real life), the way to make it work at all was via a transparent proxy, which I made via modifying the protobuf compiler a bit (see the commit history, it was rather small): https://github.com/llarsson/protobuf
