> Optimize the Refresh/Invalidate event processing by skipping unnecessary events.
> Currently, we process every event as a new event. Consider there are 5 refresh events of the same table in the event processor queue. We can process the first refresh event and skip the remaining 4 events by comparing the timestamp of the refreshed table and event time. This way we can greatly improve the performance by skipping unnecessary events.
