  27. def processPlan[T <: QueryPlan[T]](plan: T, append: (String) => Unit): Unit

    Given a input physical plan, performs the following tasks.

    Given a input physical plan, performs the following tasks.

    1. Generates the explain output for the input plan excluding the subquery plans. 2. Generates the explain output for each subquery referenced in the plan.

    Note that, ideally this is a no-op as different explain actions operate on different plan, instances but cached plan is an exception. The InMemoryRelation#innerChildren use a shared plan instance across multi-queries. Add lock for this method to avoid tag race condition.

  28. def stripAQEPlan(p: SparkPlan): SparkPlan
