Gtid是从5.6开始推出的杀手级特性，通过GTID特性，极大的提升了主备切换的效率和一致性，
在MySQL5.7.5里引入了一个新的系统表GTID_EXECUTED：

*************************** 1. row ***************************
Table: gtid_executed
Create Table: CREATE TABLE `gtid_executed` (
`source_uuid` char(36) NOT NULL COMMENT ‘uuid of the source where the transaction was originally executed.’,
`interval_start` bigint(20) NOT NULL COMMENT ‘First number of interval.’,
`interval_end` bigint(20) NOT NULL COMMENT ‘Last number of interval.’,
PRIMARY KEY (`source_uuid`,`interval_start`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
1 row in set (0.00 sec)
