Package org.apache.pinot.query.runtime.plan

Class PhysicalPlanVisitor

java.lang.Object

org.apache.pinot.query.runtime.plan.PhysicalPlanVisitor

All Implemented Interfaces:

PlanNodeVisitor<MultiStageOperator,OpChainExecutionContext>

public class PhysicalPlanVisitor
extends Object
implements PlanNodeVisitor<MultiStageOperator,OpChainExecutionContext>

This visitor constructs a physical plan of operators from a PlanNode tree. Note that this works only for the intermediate stage nodes, leaf stage nodes are expected to compile into v1 operators at this point in time.

This class should be used statically via walkPlanNode(PlanNode, OpChainExecutionContext)
