I am using a python gRPC client and make request to a service that 
responds a stream. Last checked the document says the iterator.next()
is sync and blocking. Have things changed now ? If not any ideas on overcoming this shortcoming ?
Thanks

Things have not changed; as of 2018-03 the response iterator is still blocking.
We're currently scoping out remedies that may be ready later this year, but for the time being, calling next(response_iterator) is only way to draw RPC responses.
Is grpc server response streaming still blocking?
