17.2 Replication Implementation 复制是基于master server 跟踪所有改变到他的数据库(更新,删除等等)在它的binary log. binary log 作为些所有事件修改数据的结构或者内容从server 开始启动 典型的,SELECT 语句是不被记录的因为它们既不修改数据库也不修改内容 每个slave 连接到master 请求一个binary log的拷贝. 也就是说,它从master 拉数据,相比master 推数据到slave. slave也执行从…

replication set复制集  介绍 replicattion set 多台服务器维护相同的数据副本,提高服务器的可用性,总结下来有以下好处: 数据备份与恢复 读写分离 MongoDB 复制集的结构以及基本概念 正如上图所示,MongoDB 复制集的架构中,主要分为两部分:主节点(Primary)和从节点(Secondary). 主节点:在一个复制集中只有并且必须有一个主节点,主节点也是众多实例中唯一可以接收客户端写操作的节点,当然也可以进行读操作: 从节点:从节点会复制主节点的操作,以…

1. 高级复制和流复制介绍 1.1 高级复制(Advanced Replication) 高级复制也称为对称复制,分为多主体站点复制(Multiple Master Rplication).物化视图站点复制(Materialized View Replication)和前两种的混合复制.高级复制主要是用在对称的.等同的数据库(仅限Oracle数据库之间)表之间的(单向或双向)的复制,以满足分布式应用的需求.多主体站点复制基于Oracle的触发器(Trigger)捕获DML和DDL操作,并将这些操…
