并行复制监控
最后更新于：2022-04-01 01:27:07
复制的监控依旧可以通过SHOW SLAVE STATUS\G，但是MySQL 5.7在performance_schema架构下多了以下这些元数据表，用户可以更细力度的进行监控：
~~~
mysql> show tables like 'replication%';
+---------------------------------------------+
| Tables_in_performance_schema (replication%) |
+---------------------------------------------+
| replication_applier_configuration |
| replication_applier_status |
| replication_applier_status_by_coordinator |
| replication_applier_status_by_worker |
| replication_connection_configuration |
| replication_connection_status |
| replication_group_member_stats |
| replication_group_members |
+---------------------------------------------+
8 rows in set (0.00 sec)
