   Understood! Thanks Bhavani! I'd love to take this up. I'll research and get back to you on how to proceed.
   Follow up question on above. How'd a consumer know the timings of the changed records? It asking a simple question, what changed for key K over the period of time (to recompute or even rollback something looking at the history). 
   
   Your explanation is  absolutely perfect and I tried it too, with the different times(T1/T2/T3), it works seamlessly. So, should I consider it a feature that can be added(look at the history of a record) as its completely doable. Hudi has the history of everything, it can look up by times, why can't it look up by the key? Or, is it something by design that Hudi doesn't intend to do.
   
   Thanks again, just trying to understand what questions are right in terms of Hudi design.
