I am reading Kubernetes In Action book.
At the end of chapter 4, the author states:
In normal circumstances, a CronJob always creates only a single Job for each execution configured in the schedule, but it may happen that two jobs are created at the same time, or none at all.
Does this really happen? When are the causes for this?
Edit: My question is a duplicate of this one Why in kubernetes cron job two jobs might be created, or no job might be created?
