## CronJob

CronJobs are useful for creating periodic and recurring tasks, like running backups or
sending emails. CronJobs can also schedule individual tasks for a specific time, such as
scheduling a Job for when your cluster is likely to be idle.
CronJobs are meant for performing regular scheduled actions such as backups,
report generation, and so on. Each of those tasks should be configured to recur
indefinitely (for example: once a day / week / month); you can define the point
in time within that interval when the job should start.

- `CronJobControllerV2`: Use an alternative implementation of the

The version 2 controller provides experimental performance improvements.
