Kratos

Kratos是bilibili开源的一套Go微服务框架,包含大量微服务相关框架及工具。

Goals

我们致力于提供完整的微服务研发体验,整合相关框架及工具后,微服务治理相关部分可对整体业务开发周期无感,从而更加聚焦于业务交付。对每位开发者而言,整套Kratos框架也是不错的学习仓库,可以了解和参考到bilibili在微服务方面的技术积累和经验。

Principles

  • 简单:不过度设计,代码平实简单
  • 通用:通用业务开发所需要的基础库的功能
  • 高效:提高业务迭代的效率
  • 稳定:基础库可测试性高,覆盖率高,有线上实践安全可靠
  • 健壮:通过良好的基础库设计,减少错用
  • 高性能:性能高,但不特定为了性能做hack优化,引入unsafe
  • 扩展性:良好的接口设计,来扩展实现,或者通过新增基础库目录来扩展功能
  • 容错性:为失败设计,大量引入对SRE的理解,鲁棒性高
  • 工具链:包含大量工具链,比如cache代码生成,lint工具等等

Features

  • HTTP Blademaster:核心基于gin进行模块化设计,简单易用、核心足够轻量;
  • GRPC Warden:基于官方gRPC开发,集成discovery服务发现,并融合P2C负载均衡;
  • Cache:优雅的接口化设计,非常方便的缓存序列化,推荐结合代理模式overlord
  • Database:集成MySQL/HBase/TiDB,添加熔断保护和统计支持,可快速发现数据层压力;
  • Config:方便易用的paladin sdk,可配合远程配置中心,实现配置版本管理和更新;
  • Log:类似zap的field实现高性能日志库,并结合log-agent实现远程日志管理;
  • Trace:基于opentracing,集成了全链路trace支持(gRPC/HTTP/MySQL/Redis/Memcached);
  • Kratos Tool:工具链,可快速生成标准项目,或者通过Protobuf生成代码,非常便捷使用gRPC、HTTP、swagger文档;
