> Some of the things which can be done to improve supportability of this feature:
> * Add metrics to detect issues pertaining to this feature
> # Time taken to fetch the notifications (Would be useful to have average, min, max)
> # Time taken to process a batch of events received
> # Number of times particular table was invalidated (would be useful to have some rate metric like number_of_invalidates/per_hour)
> * Ability to turn ON/OFF for this feature (possibly without the need of a restart)
