任务调度错过触发时间时的处理策略:
- 可能原因:服务重启;调度线程被阻塞,线程被耗尽;上次调度持续阻塞,下次调度被错过; - 处理策略: - 过期超10s:本地忽略,当前时间开始计算下次触发时间 - 过期超过5s:过期10s内:立即触发一次,当前时间开始计算下次触发时间

XXL-JOB的每个调度任务虽然在调度模块是并行调度执行的,但是任务调度传递到任务模块的“执行器”确实串行执行的,同时支持任务终止。

任务调度错过触发时间时的处理策略:

- 可能原因:服务重启;调度线程被阻塞,线程被耗尽;上次调度持续阻塞,下次调度被错过;

- 处理策略:
|

- 过期5s内:立即触发一次,并计算下次触发时间;
|

- 过期超过5s:忽略过期触发,计算下次触发时间;
|

- 过期超10s:本地忽略,当前时间开始计算下次触发时间
