Thanks for your reply. I am using c++.
For my first question. Can you please explain a bit more? I tested with two concurrent client requests. I saw two threads running in my service routine. My server code does not spawn any thread. So I think gRPC spawns the thread for me. That is why I want to understand the thread model. Is it one thread per one client? or there is a thread pool for all clients? Thank you!
