Types of gRPC calls
- gRPC supports both the blocking and asynchronous calls but further to that there are four types of gRPC calls that you can work with when you use this framework. The first one is Unary RPC. In this case, the client sends out a single request and the server comes back with a single response. Let us quickly see how this works. Let's say you have a Go gRPC client. The client first makes an RPC call to the server with the necessary request metadata like authentication details.
