gRPC: A Deep Dive into the Communication Pattern

In this article, I dive deeper into these communication patterns and discuss the importance of each pattern as well as how to pick the right one, according to the use case. Before I discuss each pattern, I’ll discuss what they have in common, such as how gRPC sends messages between clients and servers over the network and how request/response messages are structured.

As shown in the above code snippet, the first step is to set up the connection to the server and initiate the client.

In the client-streaming RPC pattern, the client sends multiple messages to the server and the server sends only one message in return.

In bidirectional streaming RPC, both the client and server send a stream of messages to each other.
