MySQL - Information_schema Events - How persistent or retention is managed
In MySQL, an &quot;event&quot; is not a periodic data element. It's more like a cron job (sorry— an &quot;at&quot; job in Windows). It's a routine of code with a schedule.
The content of information_schema.events is metadata about the schedule job. For instance, the code body, the schedule, etc. This information should be unchanging no matter how many times you the event runs.
It does not store any history of executions of that job, nor results or data produced by that job.
