   @bvaradar - As a follow-up question, your reply confirms that what we're 
looking for (ideally) isn't a Hudi feature currently.  Is it something you 
might be interested in supporting?
   
   In many use cases, the behaviour would likely be identical to the current - 
for snapshot queries, or for incrementally reading tables where the writer 
ensures only material changes* are written (e.g. some stream processing, or 
insert-only batch processes).  In the remaining use-cases like ours, it would 
cut back on a lot of noise + processing.   
   
   If so, I can talk to my team about contributing towards the project, since 
it would be valuable to us.

   \* I'm using 'material changes' here to describe an upsert that impacts on 
the non-`_hoodie` columns.  Either a deletion, or a change in value to one of 
those columns.
