Package org.apache.drill.exec.store.enumerable.plan

Class VertexDrel

java.lang.Object

org.apache.calcite.rel.AbstractRelNode

org.apache.calcite.rel.SingleRel

org.apache.drill.exec.store.enumerable.plan.VertexDrel

All Implemented Interfaces:

Cloneable, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.RelNode, DrillRelNode, DrillRel

public class VertexDrel
extends org.apache.calcite.rel.SingleRel
implements DrillRel

The vertex simply holds the child nodes but contains its own traits. Used for completing Drill logical planning when child nodes have some specific traits.
