      Description

      The C++ client will use primary key bounds on a scan when partition pruning tables with range partitions which are a proper prefix of the PK. The java client currently doesn't implement this optimization. I'm considering this low priority because specifying scans with PK bounds is rare, and since this only applies to tables whose range partitions are a proper prefix of the PK, it becomes rarer still.
