Pre-trained models and datasets built by Google and the community. gRPC is an open source RPC framework that makes it easy to build a heterogeneous distributed system. In general, the assumption of a server-only streaming call is that the initial message from the client contains enough information for the server to know when to stop. It picks up the traditional idea of RPC frameworks - call remote methods as easily as if they were local - while trying to avoid mistakes made by its predecessors and focusing on requirements of microservice-oriented systems. I am thinking of using a server-to-client stream to return search results. I am using the synchronous C++ API of Grpc to send messages over a bidirectional stream that needs to be kept open indefinitely. Note that there is a small performance cost to gRPC-Web, and two gRPC features are no longer supported: client streaming and bi-directional streaming.
