4.  val TEMP_LOGICAL_PLAN_TAG: TreeNodeTag[LogicalPlan]

   The temporary LogicalPlan link for query stages.

   The temporary LogicalPlan link for query stages.

   Physical nodes wrapped in a LogicalQueryStage can be shared among different physical plans and thus their usual logical links can be overwritten during query planning, leading to situations where those nodes point to a new logical plan and the rest point to the current logical plan. In this case we use temp logical links to make sure we can always trace back to the original logical links until a new physical plan is adopted, by which time we can clear up the temp logical links.

5.  def applyPhysicalRules(plan: SparkPlan, rules: Seq[Rule[SparkPlan]], loggerAndBatchName: Option[(PlanChangeLogger[SparkPlan], String)] = None): SparkPlan
