> 1.
> HepPlanner initially used for:
> - Predicate Pushdown
> - Transitive Predicate inference
> - Partition Pruning
> 2. Use Optiq's FieldTrimmer for ColumnPruner
> To begin with the rules are copies of Optiq base rules. Once Optiq is
> refactored to work on Base RelNode classes, the copied rules will be removed.
