Schedule time-specified tasks in distributed system

Question

I use ScheduledThreadPoolExecutor for tasks which have different execution times. For example, one task scheduled for 9:30 PM tonight and the other for 8:00 AM tomorrow. But if the server is shut down for some reason, the tasks disappear.

I am thinking about task persistence in a database so that I can re-trigger the failed tasks at a later time—but I guess that's not a perfect solution.

Are there any good frameworks or any other suggestions for this?

Answer 1

You can use Redis based task scheduling framework like Redisson. It also supports quartz cron experssions. Here is documentation about it
