Uses of JoinNode.JoinStrategyType in org.teiid.query.optimizer.relational.rules

Methods in org.teiid.query.optimizer.relational.rules with parameters of type JoinNode.JoinStrategyType

static float

NewCalculateCostUtil.computeCostForDepJoin(PlanNode joinNode, boolean leftIndependent, JoinNode.JoinStrategyType joinStrategy, 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.

static float

NewCalculateCostUtil.computeCostForJoin(PlanNode leftChildNode, PlanNode rightChildNode, JoinNode.JoinStrategyType joinStrategy, QueryMetadataInterface metadata, CommandContext context) Computes the cost of a Merge Join
