   > @nsivabalan Thanks for the fix. Quick comment before reviewing the diff: 
Is there a particular reason for choosing lastUpdatedTime instead of the 
HoodieInstant itself like you pointed out in your proposal ? To reduce 
complexity of understanding, I feel comparing HoodieInstants choice is better 
but I'd like to understand your reasoning.
   
   @nsivabalan I had similar view to what @n3nash was asking here. The problem 
boils down to a cache invalidation issue: the local timeline view is a cache 
and we need to compare some timestamps to decide whether to invalidate the 
cache and reload the timeline view or not. So to avoid unnecessary complexity, 
is there any strong reason why instant time can't be used here?
