shutdown

For gRPC services, GracefulStop is ideal because it allows in-flight RPCs to finish, but it can hang if handlers ignore cancellation or if clients never close streams. I wrap shutdown in a deadline: call GracefulStop in a goroutine, and if it doesn’t

A clean shutdown is part of reliability, not an afterthought. The pattern I like is: (1) start servers and workers, (2) listen for SIGINT/SIGTERM, (3) call Shutdown with a deadline, and (4) wait for background goroutines to finish. http.Server.Shutdow
