In the context of plans, of possiblity to import (and export) events from (to) third-party applications
Currently, the housekeeper clears events if their associated objects (hosts\items\triggers) are deleted
But these make it impossible to see the history of events by dynamic entities. For example, discovered by LLD. As a workaround, we can store discovered entities much longer after they are no longer discoverable. But this is a bad option - it can lead to difficulties in managing monitoring settings, and not far from performance problems.
It would be nice to be able to enable storing only events for a custom (or default by housekeeper) time after the objects themselves are deleted
