   @szehon-ho : 
   Say for `partition-a` I have `record_count`=6 and `file_count`=2. [3 records in each file]
   Now, I do position delete which marks 3 records in file1 as deleted for `partition-a`. 
   
   So, are you suggesting instead of decrementing `record_count` to 3 and incrementing `file_count` to 3,
   increment `pos_delete_record_count`=3, `pos_delete_file_count`=1 ?
   
   In this case, the user has to manually calculate that now instead of 6 there are 3 total records and instead of 2 files, now need to scan 3 files.
   
   Sounds good to me. It avoids confusion. 
   
   What about the global deletes?  (row level delete for unpartitioned data). Does it come under the partition value `null`?
