java.lang.Object

org.apache.calcite.rel.AbstractRelNode

org.apache.drill.exec.planner.logical.DrillDirectScanRel

All Implemented Interfaces:

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

public class DrillDirectScanRel
extends org.apache.calcite.rel.AbstractRelNode
implements DrillRel

Logical RelNode representing a DirectGroupScan. This is not backed by a DrillTable, unlike DrillScanRel.
