> Partition Pruner has logic reusable like
> 1. walk through operator tree
> 2. walk through operation tree
> 3. create pruning predicate
> The first candidate is list bucketing pruner.
> Some consideration:
> 1. refactor for general use case not just list bucketing
> 2. avoid over-refactor by focusing on pieces targeted for reuse
