java.lang.Object

org.apache.drill.exec.physical.base.AbstractPhysicalVisitor<PhysicalOperator,Materializer.IndexedFragmentNode,ExecutionSetupException>

org.apache.drill.exec.planner.fragment.contrib.ExchangeRemoverMaterializer

All Implemented Interfaces:

PhysicalVisitor<PhysicalOperator,Materializer.IndexedFragmentNode,ExecutionSetupException>

public class ExchangeRemoverMaterializer
extends AbstractPhysicalVisitor<PhysicalOperator,Materializer.IndexedFragmentNode,ExecutionSetupException>

Materializer visitor to remove exchange(s) NOTE: this Visitor does NOT set OperatorId, as after Exchange removal all operators need renumbering Use OperatorIdVisitor on top to set correct OperatorId
