Uses of CardinalityEstimation in se.liu.ida.hefquin.engine.queryproc.impl.poptimizer.cardinality

Classes in se.liu.ida.hefquin.engine.queryproc.impl.poptimizer.cardinality that implement CardinalityEstimation

Modifier and Type	Class	Description
class	CardinalityEstimationImpl	This class implements an approach to cardinality estimation that is based on the following two ideas: First, for leaf nodes in the given plans, which are request operators, the implementation issues cardinality requests to the respective federation members.
class	MinBasedCardinalityEstimationImpl	This class implements a cardinality estimation approach that relies on the cardinalities of subPlans.
