E.g. store the user id related to a trigger and then query like user_id=555. Previously, I used to query the database directly but this is naturally not a good way.

I want my jobs to execute in every X seconds, there's one to one matching between job and X. Also during runtime there can be registered new jobs with their own intervals. I've tried to write cron expression for such scenarios, but in documentation there's written that value of seconds can't be more than 59. So cron expression like this...
