[GitHub] [shardingsphere-elasticjob] Technoboy- opened a new issue #1389: How to handle the resources that cause by job execute only once?
Technoboy- opened a new issue #1389:
URL: https://github.com/apache/shardingsphere-elasticjob/issues/1389
Suppose we have 100 jobs that every job trigger only once like cron '0 0 0 22 8 ? 2020'.
What I mean is that it will be trigger only once sometime in the future. After that , the ejob resource retains in the memory.
How could we handle this, like shutdown the instance or cleanup the zk datas ?
If we support centralized scheduling, we can handle it easily. But could we need to support in lite or can we discuss out a good idea for this?

Yes, but users really have the need to trigger only once, no more.
This issue is produced by #1378 . And want to discuss more about it.

Even jobs run only once, we still need to keep job configs and status in ZooKeeper.
Because we can not assume that user never change the config and trigger jobs again.

Even the job run only once, we still need to keep job config and status in zk.
Because we can not assume user do not change the config and trigger job again.
