(3)分片下级为副本(replica),可对分片配置多个副本,默认最少0个,不同副本不能用同一个ClickHouse实例。 (4)internal_replication 用来控制当数据写入时(必须是Replicated*的表),由分片自己负责副本间的数据复制,否则分布式表的副本数据写入需要由Distributed引擎来负责。

一开始我们有两副本,Replica #1 某时刻出现故障,于是替换了一个新的节点上来,新节点会开始同步数据,白框部分是已经同步过的,虚线黄框是正在恢复的数据,新写入的白色框部分就是新写入的数据。如果此时两个机器的数据同步压力比较大或查询压力比较大,就会出现 Replica #1 新写入的数据没有及时同步到 Replica #2 ,...
