=============================================

启动的时候，

SELECT * FROM qrtz_LOCKS WHERE SCHED_NAME = 'dufy_test' AND LOCK_NAME = 'STATE_ACCESS' FOR UPDATE

 

 

执行trigger的时候：

SELECT * FROM qrtz_LOCKS WHERE SCHED_NAME = 'dufy_test' AND LOCK_NAME = 'TRIGGER_ACCESS' FOR UPDATE

 

qrtz_SCHEDULER_STATE 会不断的被更新， 在启动的时候 插入一次，

 

也会删除

2021-07-29 07:17:18 | Time 1 ms | statement-1 | DELETE FROM qrtz_SCHEDULER_STATE WHERE SCHED_NAME = 'dufy_test' AND INSTANCE_NAME = 'DESKTOP-MBMDPHH1627513038976'

 

 

如果多个实例， 就会在 qrtz_SCHEDULER_STATE 存在多行；；

 

 

数据库表的变化

第一个节点会在 qrtz_lock 表 新增两行：

 

 

每次有集群的节点启动的时候， 会在表QRTZ_SCHEDULER_STATE 加入一行。 退出的时候， 删除一行。

 

但是最后一个节点退出不会删除， 因为 它 可能来不及 自己删除。
