Have support multi process？

[boylegu]

My code：

server = Server(50055, num_processes=5)

server.add_service(JobEngine().service)

server.serve(backend="asyncio")

Exception： TypeError: init() got an unexpected keyword argument 'num_processes'

I don't understand why your example code is shown as if good.

• misc/greeter/failing_server.py
• misc/greeter/main_pingpong_servicer.py

Could you tell me why？

environment： purerpc==0.5.2 python == 3.6

Hi! With multiprocessing we cannot correctly pass context_manager and setup_fn parameters to Server.add_service if they allocate system resources (connections to databases, for example). On Linux, you can run multiple instances of your server on the same port with SO_REUSEPORT option, this will effectively load balance the traffic on TCP connection level, if this is what you want. I will be updating example code shortly.
