Interface CardinalityEstimationWorker

All Known Implementing Classes:
CardinalityEstimationWorkerImpl
public interface CardinalityEstimationWorker
Implementations of this class complete the cardinality estimation process for a given query plan (or for multiple such plans) in which every nullary subplan is already annotated with its cardinality estimate.
