Steps to reproduce:

1. Configure Trigger storage period like 365 days for Housekeeper settings
2. Create noisy trigger and collect 30M of events as an example
3. Find that Trigger is bad and remove it
4. Problems will be removed, Trigger will be removed

Result:

1. Events will stay until 365 days will pass

Expected:

1. Events removed or there will be a way to force that

The more days you have configured for a trigger data, the more orphaned data will be inside events table due to the lifecycle of triggers (added, removed, etc...).
