| Description |
|
Add conjunctive queries, where predicate order matters a lot due to different selectivity of the predicates. This will test the ability of the optimizer to order the predicates according to their selectivity. We should specifically craft a case where heuristic CE allows us to order the predicates well, and a case where heuristic CE does poorly (for future regression testing). |
