Rpcx

Rpcx is a RPC (Remote Procedure Call) framework like Alibaba Dubbo and Weibo Motan.Some of the advantages on using Rpcx:

  • Simple: easy to learn, easy to develop, easy to integrate and easy to deploy
  • Performance: high performance (>= grpc-go)
  • Cross-platform: support raw slice of bytes, JSON, Protobuf and MessagePack. Theoretically it can be used with java, php, python, c/c++, node.js, c# and other platforms
  • Service discovery and service governance: support zookeeper, etcd and consul.

RPCx__

  • Purpose: High-performance RPC framework.
  • Key Features: Multiple codecs (Protobuf, JSON), plugins for service discovery, rate limiting, and tracing.
  • Best For: High-performance RPC communication between services.

Example: 

s := server.NewServer()
s.RegisterName("Arith", new(Arith), "")
s.Serve("tcp", ":8972")

RPCx__ - High-Performance RPC

Solution Example: Real-time Online Gaming

  • Use Case: In an online multiplayer game, players’ interactions need to be communicated between game servers with low latency.
  • Framework Usage: Using RPCx, game servers can handle real-time communication between players by calling remote methods with minimal delay and high performance.
  • Workflow:
  1. A GameServer uses RPC to request updates from a central PlayerStatsService.
  2. The PlayerStatsService can return the latest statistics in real-time.

Example: 

client := client.NewClient(client.DefaultOption)
client.Connect("tcp", "localhost:8972")
var reply int
err := client.Call(context.Background(), "GameServer.UpdatePlayerStats", &args, &reply)
