Hello,
We have an existing multithreaded c++ server that works by passing messages between threads to avoid synchronization. Now if I add an async gRPC server, how would I pass a gRPC context to the appropriate thread and complete the call after getting a response?
It is similar to someone asking how to integrate gRPC async loop with other event loops, but I have not seen any solution. For example, libevent has ‘runInEventThread’ method to pass a function to the event thread to execute.

Is your existing server a gRPC server, or is just a TCP or HTTP server and you want add another gRPC server and share the port?

It is just a TCP server and will add gRPC service on a different port.
Reading the async example, it appears that I can pass a CallData object to another thread using a queue (different from cq) and respond from that thread and finally get completion event back in the gRPC thread and I can delete the CallData object at that time. It should work as ‘cq’ is safe to call from multiple threads.
Thank you.

Yes, that would work.
