基于gtid的
MySQL基于gtid的主从复制
Gtid概念
从 MySQL 5.6.5 开始新增了一种基于 GTID 的复制方式。通过 GTID保证了每个在主库上提交的事务在集群中有一个唯一的ID。这种方式强化了数据库的主备一致性，故障恢复以及容错能力。在原来基于二进制日志的复制中，从库需要告知主库要从哪个偏移量进行增量同步，如果指定错误会造成数据的遗漏，从而造成数据的不一致。借助GTID，在发生主备切换的情况下，MySQL的其它从库可以自动在新主库上找到正确的复制位置，这大大简化了复杂复制拓扑下集群的维护，也减少了人为设置复制位置发生误操作的风险。另外，基于GTID的复制可以忽略已经执行过的事务，减少了数据发生不一致的风险。
什么是Gitd
GTID (Global Transaction ID) 是对于一个已提交事务的编号，并且是一个全局唯一的编号。 GTID 实际上 是由UUID+TID 组成的。其中 UUID 是一个 MySQL 实例的唯一标识。TID代表了该实例上已经提交的事务数量，并且随着事务提交单调递增。下面是一个GTID的具体形式：3E11FA47-71CA-11E1-9E33-C80AA9429562:23，冒号分割前边为uuid，后边为TID。GTID 集合可以包含来自多个 MySQL 实例的事务，它们之间用逗号分隔。如果来自同一MySQL实例的事务序号有多个范围区间，各组范围之间用冒号分隔。例如： e6954592-8dba-11e6-af0e-fa163e1cf111:1-5:11-18,e6954592-8dba-11e6-af0e-fa163e1cf3f2:1-27 可以使用show master status实时查看当前事务执行数
Gtid的作用
Gtid采用了新的复制协议
旧协议是，首先从服务器上在一个特定的偏移量位置连接到主服务器上一个给定的二进制日志文件，然后主服务器再从给定的连接点开始发送所有的事件。
新协议有所不同，支持以全局统一事务ID (GTID)为基础的复制。当在主库上提交事务或者被从库应用时，可以定位和追踪每一个事务。GTID复制是全部以事务为基础，使得检查主从一致性变得非常简单。如果所有主库上提交的事务也同样提交到从库上，一致性就得到了保证。
Gtid的工作原理
①当一个事务在主库端执行并提交时，产生GTID，一同记录到binlog日志中。
②binlog传输到slave,并存储到slave的relaylog后，读取这个GTID的这个值设置gtid_next变量，即告诉Slave，下一个要执行的GTID值。
③sql线程从relay log中获取GTID，然后对比slave端的binlog是否有该GTID。
④如果有记录，说明该GTID的事务已经执行，slave会忽略。
⑤如果没有记录，slave就会执行该GTID事务，并记录该GTID到自身的binlog，
在读取执行事务前会先检查其他session持有该GTID，确保不被重复执行。
⑥在解析过程中会判断是否有主键，如果没有就用二级索引，如果没有就用全部扫描。
