> Fix For: 1.4.0
>
>
> 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.
