Summary: RuleBasedPlanner now generates only the regular ScanAll operations, and Filter operations are appended as soon as possible. The newly added Rewrite step, takes this operator tree and replaces viable Filter & ScanAll operators with appropriate ScanAllBy<Index> operator. This change ought to simplify the behaviour of DistributedPlanner when that stage is moved before the indexed lookup rewrite. Showing unoptimized plan in interactive planner is also supported.
