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.
