zebra's Introduction

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
