问题描述
我已经部署了单主组复制。我想确保我的副本数据与主数据库同步,这意味着我想找出可能落后于主数据库的秒数。我已运行e sql命令来查找组的状态,如:
MysqL> show slave status for channel 'group_replication_recovery'\G;
*************************** 1. row ***************************
Slave_IO_State:
Master_Host: <NULL>
Master_User: repl
Master_Port: 0

Network_Namespace:
1 row in set (0.00 sec)
从上面的输出中,有两个字段Retrieved_Gtid_Set
和Executed_Gtid_Set
。比较这些字段,我可以发现主数据库和副本数据库之间的数据一致性/数据同步。但是Retrieved_Gtid_Set
始终设置为空。有什么解决方法可以找出Retrieved_Gtid_Set
吗?
