A rule collection can be deleted (admin screen), if no rules (inputs) are maintained for it.
Anyway, if that collection has a history of (deleted) events assigned to it, those events will not get deleted, and stay in the database.
There are different options to deal with this:
- Do not allow the deletion of a rule collections, if history events are associated with it.
- Reconfirm deletion of a rule collection, if history events are associated with it, e.g. "There exist a history for the rule collection. Do you really want to delete it? [Yes] [No]"
- Just delete the history without further communication.
I am curious for your thoughts on this.
