Is there an example how to manage bidirectional streams on server side?

Describe the question
A clear and concise description of what the question is.
I'm trying to implement grpc-service with bidirectional method, and found that there is no clean way how to close stream on server side. All what i can do - just kill process.

I've found a way with raising exception, but is it normal for closing connection?
