otter's Introduction

项目背景

   阿里巴巴B2B公司,因为业务的特性,卖家主要集中在国内,买家主要集中在国外,所以衍生出了杭州和美国异地机房的需求,同时为了提升用户体验,整个机房的架构为双A,两边均可写,由此诞生了otter这样一个产品。

   otter第一版本可追溯到04~05年,此次外部开源的版本为第4版,开发时间从2011年7月份一直持续到现在,目前阿里巴巴B2B内部的本地/异地机房的同步需求基本全上了otte4。

目前同步规模:
  1. 同步数据量6亿
  2. 文件同步1.5TB(2000w张图片)
  3. 涉及200+个数据库实例之间的同步
  4. 80+台机器的集群规模

项目介绍

名称:otter ['ɒtə(r)]

译意: 水獭,数据搬运工

语言: 纯java开发

定位: 基于数据库增量日志解析,准实时同步到本机房或异地机房的mysql/oracle数据库. 一个分布式数据库同步系统

工作原理

原理描述:

1. 基于Canal开源产品,获取数据库增量日志数据。 什么是Canal, 请点击

2. 典型管理系统架构,manager(web管理)+node(工作节点)

    a. manager运行时推送同步配置到node节点

    b. node节点将同步状态反馈到manager上

3. 基于zookeeper,解决分布式状态调度的,允许多node节点之间协同工作.
