I’ve been writing a lot of Go gRPC services these days at work - database proxies, metadata services, storage orchestration control plane, etc. They require me to go a bit deeper into protobuf and Go gRPC tooling than you’d typically need to. So I started poking around OSS gRPC codebases to pick up conventions.
I was mainly looking for pointers on how to organize protobuf definitions, wire up server-side metrics and interceptors, and build ergonomic client wrappers. The default answer here is often “go read the Docker or Kubernetes codebase.” But both of those are pretty huge and take forever to get accustomed to.
