Sure @rkkalluri - and thank you again for your help and what you do the for
the community.
I switched from a timestamp partition in yyyyMM format to a range partition
on the record key. The record key on the table is autoincrementing so it lent
itself well to range partitioning and still leveraging the bloom index.
