> We miss opportunities to prune whole tablets from scans in response to start/stop primary keys and predicates on flex partitioned tables.  The result is that scans for just a single row of a flex-partitioned table require touching every tablet.  This is an important optimization for hash bucketed tables with selective scan workloads.
