gRPC Python Non-Blocking Streaming RPC Client Example

The goal of this example is to demonstrate how to handle streaming responses without blocking the current thread. Effectively, this can be achieved by converting the gRPC Python streaming API into callback-based.

In this example, the RPC service Phone simulates the life cycle of virtual phone calls. It requires one thread to handle the phone-call session state changes, and another thread to process the audio stream. In this case, the normal blocking style API could not fulfill the need easily. Hence, we should asynchronously execute the streaming RPC.

Steps to run this example

Start the server in one session

python3 server.py

Start the client in another session

python3 client.py
