<Server Threadpool Exhausted> ResourceQuota::SetMaxThreads - C++ - How does it work?

[Rajanarayana A]

Hello,

Can anyone please explain how ResourceQuota::SetMaxThreads actually works under the hood?

For example, if I set the max threads to 2 

rq.SetMaxThreads(2);

One thread for completion queue and another thread to serve RPC. Is this understanding correct?

What happens when we get burst of RPCs(Say 50 RPCs at a given moment)? Since we have defined maximum threads as 2, will few RPCs are rejected by "Server Threadpool Exhausted" ? 

Thanks,

Raj

Sorry, I forgot to mention that this is Sync gRPC server.
