Class ServerPlanRequestVisitor

java.lang.Object

org.apache.pinot.query.runtime.plan.server.ServerPlanRequestVisitor

All Implemented Interfaces:

PlanNodeVisitor<Void,ServerPlanRequestContext>

public class ServerPlanRequestVisitor
extends Object
implements PlanNodeVisitor<Void,ServerPlanRequestContext>

Plan visitor for direct leaf-stage server request. This should be merged with logics in InstancePlanMakerImplV2 in the future to directly produce operator chain. As of now, the reason why we use the plan visitor for server request is for additional support such as dynamic filtering and other auxiliary functionalities.
