Using Flipper (0.28.3) in Rails I want a way to detect when the most recent change to a feature. I want to do this so I can use it as part of a cache key to invalidate view caches whenever a change is made to flipper.
This has to include features being deleted.
We are using the flipper-active_record gem, and was hoping that UPDATED_AT on FLIPPER_GATES would reflect the changes I need. However this doesn't seem to leave any record of gates being removed or features being deleted.
Ideally I don't want to be storing the full state of Flipper and comparing with the current state, I also don't need to specialise this across different actors. I just need the latest change to Flipper, globally.
Is there a source for this? or a way to find it?
