Modifier and Type	Method	Description
protected PhysicalPlan	CostModelBasedGreedyJoinPlanOptimizerImpl.GreedyEnumerationAlgorithm.addNextBestJoin(PhysicalPlan currentPlan)	Creates a binary join plan with the given plan as left child and one of the remaining subplans (see CostModelBasedGreedyJoinPlanOptimizerImpl.GreedyEnumerationAlgorithm.subplans) as the right child.
protected PhysicalPlan	CostModelBasedGreedyJoinPlanOptimizerImpl.GreedyEnumerationAlgorithm.chooseFirstSubplan()	Compares all available subplans (see CostModelBasedGreedyJoinPlanOptimizerImpl.GreedyEnumerationAlgorithm.subplans) in terms of their respective costs (as estimated by using the CostModelBasedGreedyJoinPlanOptimizerImpl.costModel) and returns the one with the lowest estimated cost.
PhysicalPlan	JoinPlanOptimizer.determineJoinPlan(List<PhysicalPlan> subplans, QueryProcContext ctxt)	Returns a plan that combines the given subplans using binary joins.
default PhysicalPlan	JoinPlanOptimizer.determineJoinPlan(PhysicalPlan[] subplans, QueryProcContext ctxt)	Returns a plan that combines the given subplans using binary joins.
