Zebra

Introduction

Zebra是一个基于JDBC API协议上开发出的高可用、高性能的数据库访问层解决方案，是美团点评内部使用的数据库访问层中间件。具有以下的功能点： - 配置集中管理，动态刷新 - 支持读写分离、分库分表 - 丰富的监控信息在CAT上展现 - 异步化数据库请求，多数据源支持

Core Value

  • 简化了读写分离、分库分表的开发工作，使得业务方在分库分库、读写分离的情况下，依然可以像操作单个库那样去操作，屏蔽底层实现的复杂性，对业务透明。 提供了从读写分离到分库分表全生命周期的技术支持。
  • 完善的监控体系帮助开发掌控数据库请求的整个链路，快速定位问题。
  • dao层扩展功能

Modules

  • zebra-client（核心） : 除了监控外，几乎zebra所有核心功能，如读写分离、分库分表、就近路由、流量控制
  • zebra-cat-client（可选）: 提供端到端的监控，将监控信息上报到CAT监控平台
  • zebra-dao(可选)：对mybatis的轻量级封装，兼容mybatis原有的功能，并额外提供了异步化接口、分页插件、多数据源等功能
  • zebra-admin-web：zebra配置管理平台 用于管理zk和保存在zk中的zebra配置
  • zebra-sample: zebra客户端使用的demo
