      Description

      It seems that the partition prune rule may be fired multiple times, even after the first rule execution has pushed the filter into the scan operator. Since partition prune has to build the vectors to contain the partition /file / directory information, to invoke the partition prune rule unnecessary may lead to big memory overhead.

      Drill planner should avoid the un-necessary partition prune rule, in order to reduce the chance of hitting OOM exception, while the partition prune rule is executed.
