static NewCalculateCostUtil.DependentCostAnalysis

NewCalculateCostUtil.computeCostForDepJoin(PlanNode joinNode, boolean leftIndependent, QueryMetadataInterface metadata, CapabilitiesFinder capFinder, CommandContext context) Computes the cost of a Dependent Join The worst possible cost will arise from a high independent ndv (many dependent sets) and a low dependent ndv (possibly many matches per set) This logic uses the same assumption as criteria in that ndv is used as a divisor of cardinality.
