Server-Streaming gRPC Calls
Learn about the server-streaming call type in gRPC and how to implement it.
We'll cover the following...
A server-streaming call works by sending a stream of messages from the server back to the client instead of just supplying a single response. The client will still need to trigger the stream by sending its initial request to the server. Then the server can open the stream and write any arbitrary number of messages into it.
