kingbus简介

kingbus是一个基于raft强一致协议实现的分布式MySQL binlog 存储系统。它能够充当一个MySQL Slave从真正的Master上同步binglog,并存储在分布式集群中;同时又充当一个MySQL Master将集群中的binlog 同步给其他Slave。kingbus具有如下特性:

  • 兼容MySQL 复制协议,通过Gtid方式同步Master上的binlog,同时支持slave通过Gtid方式从kingbus拉取binlog。

  • 跨地域数据复制,kingbus通过raft协议支持跨地域间的数据复制。写入到集群的binlog数据在多个节点间保证强一致,并保证binlog顺序与master上完全一致。

  • 高可用,由于kingbus是构建在Raft强一致协议之上,能够实现集群中过半数节点存活的情况下,整个binlog拉取和推送服务高可用。

为什么需要kingbus?

  1. 降低Master的负载和网络传输流量。在一主多从的复制拓扑中,Master需要发送binlog到各个slave,如果slave过多的话,网络流量很有可能达到Master的网卡上限,同时Master上负载也会过高。
  2. 简化主从复制拓扑,不再需要多级复制。
  3. 简化Master Failover流程,只需将其中的一个Slave提升为Master,并将kingbus指向新的Master,其他slave复制拓扑保持不变。
  4. 减少Master上的binlog存储空间,将binlog都存储到kingbus中。
  5. 支持异构复制。其他异构复制组件可以连接在kingbus上。
