   Thanks for pinging me, @PiyushHurpadeDremio. Looks like the next step is to 
agree on a design for tracking partition stats?
   
   I see from the description that this is adding a file to each snapshot that 
has an entry per partition tuple that has file and record counts. Do you think 
that this is going to be sufficient for other partition stats as well? What is 
the underlying use case you're trying to solve with number of files and number 
of rows?
   
   Would it also make sense to add partition-level stats like column 
lower/upper bounds, value counts, null counts, and NaN counts?
