DRILL-3765: Move partitioning pruning to HepPlanner to avoid the perfâ¦
â¦ormance overhead for redundant rule execution.
Add fall back option in planner.
Run the regression/unit with this feature turned on /off.
Please see DRILL-3765 for some performance number.
Regarding the planner options:
1. planner.enable_join_hep_opt is replaced with planner.enable_hep_opt.
This controls whether HepPlanner would be used in drill logical planning. If
this option is off, it would fall back to Volcano planner.
2. Add new planning option : planner.enable_hep_partition_pruning, which
will turn on/off this feature. If this option is off, it will fall back to the
code prior to this patch.
