Including Group-By in Query Optimization
Summary: Push group-by past joins to enable early aggregation and potential cost savings. Introduce a greedy conservative heuristic to modify System-R–style optimizers, yielding equal-or-better plans than traditional ones, with extensions to Select-Distinct via cost-based duplicate elimination.
