概述

  Nebula是一个产线级的网络服务框架和分布式服务解决方案项目,适用于即时通讯、数据采集、实时计算、消息推送、接入网关、web后台服务等应用场景。

  原生支持proto3、resp、http、https、http2、grpc、websocket多种应用层通信协议。

  详细的文档,入门简单,扩展容易,开发效率高。

  依赖的第三方库极少,开发和部署无成本。

  基于channel、类actor模型异于传统rpc调用的无锁并发编程方式,进程&线程模型一键配置。

  支持插件式动态加载,不停服务热更新更方便。

  不仅是一个网络框架,还是一个十分通用的业务框架。选择Nebula,不必在网络框架之上再做业务框架封装。

  代码结构清晰,可读性非常好。

部分生产应用(按时间倒序)

  • 计算机设备行业X公司智能设备数据采集服务:基于http2协议通信向智能设备终端发连接,终端以http2流响应回传所采集的数据。
  • 移动互联网行业O公司特征画像服务:基于redis协议、grpc协议、http协议通信,带复杂数据逻辑的redis数据代理,既是redis服务端也是redis客户端,高峰tps 33万。
  • 移动互联网行业O公司推荐引擎:基于grpc协议和redis协议通信,计算密集型服务。
  • 移动互联网行业O公司向量搜索服务:基于grpc协议和http协议通信,计算密集型服务。
  • 计算机设备行业X公司支付网关:基于https协议通信,支付网关作为手持设备的https服务端和银行付款api的https客户端。
  • 移动互联网行业O公司http接入网关:基于http协议,包括条件转发、hash路由、服务熔断与恢复、过载保护、服务降级等功能。
  • 游戏行业G公司即时通讯系统:基于nebula协议和http协议通信,包括接入服务、逻辑服务、缓存代理服务、数据库代理服务、注册中心、配置中心等。
  • O2O行业J公司埋点数据采集和实时分析系统:基于http协议和nebula协议通信,包括接入服务、逻辑服务、数据库代理服务、注册中心。

开始

  Nebula是个较完备的项目,也是一个你难得一见的依赖很少的项目,提供了许多开箱即用的功能,并提供了一键安装脚本,NebulaBootstrap,让开发者可以快速部署和体验Nebula。相信部署和体验之后,你会对Nebula产生兴趣,这将会是一个可以广泛应用的框架,基于NebulaBootstrap提供的分布式解决方案可以很方便地用C++开发微服务应用。Nebula的相关项目就是学习和使用Nebula框架最好的例子。

  • 初步合并@nebim写的CodecResp和CodecHttp2
  • 增加第三方cityhash
  • 更新CJsonObject
  • bug修复

v1.2

  • 增加延迟启动功能:因loader加载大量本地数据文件而延迟绑定端口提供服务并向Beacon注册。
  • 线程模式下Manager不再监控和重启不健康的worker和loader服务。

v1.1

  • 增加Worker的线程支持

v1.0

  • 从Manager和Worker类中分离出网络分发功能类Dispatcher和Actor创建及管理类ActorBuilder
  • Manager进程支持Actor类的使用,将Manager系统管理功能分离到Cmd类和Step类中
  • 增加Loader进程类型
  • 优化Actor通过反射动态创建实例
