rpcx

Faster multil-language bidirectional RPC framework in Go, like alibaba Dubbo and weibo Motan in Java, but with more features, Scale easily. http://rpcx.site

      

Cross-Languages

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 Client: You can use rpcx-java to 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.

Installation

install the basic features:

go get -u -v github.com/smallnest/rpcx/...

If you want to use reuseport、quic、kcp, zookeeper, etcd, consul registry, use those tags to go get 、 go build or go run. For example, if you want to use all features, you can:

go get -u -v -tags "reuseport quic kcp zookeeper etcd consul ping rudp utp" github.com/smallnest/rpcx/...

tags:

• quic: support quic transport
• kcp: support kcp transport
• zookeeper: support zookeeper register
• etcd: support etcd register
• consul: support consul register
• ping: support network quality load balancing
• reuseport: support reuseport

Features

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

rpcx 3.0 has been refactored 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：Failover, Failfast, Failtry.
• Load banlancing：support 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.

Performance

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