Notice: etcd

plugin has been moved to rpcx-etcd


A tcpdump-like tool added: rpcxdumpใ€‚ You can use it to debug communications between rpcx services and clients.


you can use other programming languages besides Go to access rpcx services.

  • rpcx-gateway: You can write clients in any programming languages to call rpcx services via rpcx-gateway
  • http invoke: you can use the same http requests to access rpcx gateway
  • Java Services/Clients: You can use rpcx-java to implement/access rpcx servies via raw protocol.

If you can write Go methods, you can also write rpc services. It is so easy to write rpc applications with rpcx.


install the basic features:

go get -v

If you want to use

registry, use those tags to
go get
go build
go run
. For example, if you want to use all features, you can:
go get -v -tags "quic kcp"

tags: - quic: support quic transport - kcp: support kcp transport - ping: support network quality load balancing - utp: support utp transport

Which companies are using rpcx?


rpcx is a RPC framework like Alibaba Dubbo and Weibo Motan.

rpcx is created for targets: 1. Simple: easy to learn, easy to develop, easy to intergate and easy to deploy 2. Performance: high perforamnce (>= grpc-go) 3. 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 4. Service discovery and service governance: support zookeeper, etcd and consul.

It contains below features - Support raw Go functions. There's no need to define proto files. - Pluggable. Features can be extended such as service discovery, tracing. - Support TCP, HTTP, QUIC and KCP - Support multiple codecs such as JSON, Protobuf, MessagePack and raw bytes. - Service discovery. Support peer2peer, configured peers, zookeeper, etcd, consul and mDNS. - Fault tolerance๏ผšFailover, Failfast, Failtry. - Load banlancing๏ผšsupport Random, RoundRobin, Consistent hashing, Weighted, network quality and Geography. - Support Compression. - Support passing metadata. - Support Authorization. - Support heartbeat and one-way request. - Other features: metrics, log, timeout, alias, circuit breaker. - Support bidirectional communication. - Support access via HTTP so you can write clients in any programming languages. - Support API gateway. - Support backup request, forking and broadcast.

rpcx uses a binary protocol and platform-independent, which means you can develop services in other languages such as Java, python, nodejs, and you can use other prorgramming languages to invoke services developed in Go.

There is a UI manager: rpcx-ui.


Test results show rpcx has better performance than other rpc framework except standard rpc lib.

The benchmark code is at rpcx-benchmark.

Listen to others, but test by yourself.

Test Environment

  • CPU: Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz, 32 cores
  • Memory: 32G
  • Go: 1.9.0
  • OS: CentOS 7 / 3.10.0-229.el7.x86_64

Use - protobuf - the client and the server on the same server - 581 bytes payload - 500/2000/5000 concurrent clients - mock processing time: 0ms, 10ms and 30ms

Test Result

mock 0ms process time

Throughputs Mean Latency P99 Latency

mock 10ms process time

Throughputs Mean Latency P99 Latency

mock 30ms process time

Throughputs Mean Latency P99 Latency


You can find all examples at rpcxio/rpcx-examples.

The below is a simple example.


    // define example.Arith

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


    // prepare requests

d := client.NewPeer2PeerDiscovery("[email protected]"+addr, "")
xclient := client.NewXClient("Arith", client.Failtry, client.RandomSelect, d, client.DefaultOption)
defer xclient.Close()
err := xclient.Call(context.Background(), "Mul", args, reply, nil)
