Class LocalExecutionPlanner

java.lang.Object

org.apache.iotdb.db.mpp.plan.planner.LocalExecutionPlanner

public class LocalExecutionPlanner
extends java.lang.Object

Used to plan a fragment instance. Currently, we simply change it from PlanNode to executable Operator tree, but in the future, we may split one fragment instance into multiple pipeline to run a fragment instance parallel and take full advantage of multi-cores
