| class  | PlanSelectionFuseAllThis plan selection heuristic aims for maximal fusion, which
 potentially leads to overlapping fused operators and thus,
 redundant computation but with a minimal number of materialized
 intermediate results. | 
| class  | PlanSelectionFuseCostBasedThis cost-based plan selection algorithm chooses fused operators
 based on the DAG structure and resulting overall costs. | 
| class  | PlanSelectionFuseCostBasedV2This cost-based plan selection algorithm chooses fused operators
 based on the DAG structure and resulting overall costs. | 
| class  | PlanSelectionFuseNoRedundancyThis plan selection heuristic aims for fusion without any redundant 
 computation, which, however, potentially leads to more materialized 
 intermediates than the fuse all heuristic. |
