gRPC

gRPC (gRPC Remote Procedure Calls) is a protocol for calling functions in distributed computer systems . It is based on the HTTP / 2 standard and protocol buffers .

functionality

IDL

The interface is specified independently of a specific programming language using an interface description language (IDL).

message HelloRequest {
  string greeting = 1;
}

message HelloResponse {
  string reply = 1;
}

service HelloService {
  rpc SayHello(HelloRequest) returns
  (HelloResponse);
}

Using the protocol buffer compiler 'protoc' (and a plug-in for gRPC), server and client code, so-called stubs , can be generated from this description .

On the server side, the stub is usually equipped with the actual business logic through inheritance. On the client side, the stub in connection with a transport (which is connected to the server) is responsible for calls to the server.
