gRPC server-side streaming is implemented by defining a service in the Protocol Buffers specification language, where the client sends a single request to the server and gets a stream to read a sequence of messages back. The client reads from the returned stream until there are no more messages. This is done using the ‘stream’ keyword in the service definition.
Server-side streaming can be used when you need to send a lot of data such as large datasets or files from the server to the client. It’s also useful for “real-time” applications where the server needs to push updates to the client asynchronously, like live sports scores or stock market prices.
