Goalng gRPC practise examples.
In gRPC, a client application can directly call a method on a server application on a different machine as if it were a local object, making it easier for you to create distributed applications and services. As in many RPC systems, gRPC is based around the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types. On the server side, the server implements this interface and runs a gRPC server to handle client calls. On the client side, the client has a stub (referred to as just a client in some languages) that provides the same methods as the server.
Unary RPCs :
rpc SayHello(HelloRequest) returns (HelloResponse);
Server streaming RPCs:
rpc LotsOfReplies(HelloRequest) returns (stream HelloResponse);
Client streaming RPCs:
rpc LotsOfGreetings(stream HelloRequest) returns (HelloResponse);
Bidirectional streaming RPCs:
rpc BidiHello(stream HelloRequest) returns (stream HelloResponse);
