org.apache.drill.exec.resourcemgr.config.QueueAssignmentResult

public class QueueAssignmentResult
extends Object

Used to keep track of selected leaf and all rejected ResourcePool for the provided query. It is used by ResourcePoolImpl.visitAndSelectPool(QueueAssignmentResult, QueryContext) to store information about all the matching and non-matching ResourcePools for a query when ResourcePool selector is evaluated against query metadata. Later it is used by ResourcePool.visitAndSelectPool(QueueAssignmentResult, QueryContext) to apply QueueSelectionPolicy to select only one queue out of all the selected queues for a query. It also provides an API to dump all the debug information to know which pools were selected and rejected for a query.
