  32. lazy val toRdd: RDD[InternalRow]

    Internal version of the RDD.

    Internal version of the RDD. Avoids copies and has no schema. Note for callers: Spark may apply various optimization including reusing object: this means the row is valid only for the iteration it is retrieved. You should avoid storing row and accessing after iteration. (Calling collect() is one of known bad usage.) If you want to store these rows into collection, please apply some converter or copy row which produces new object per iteration. Given QueryExecution is not a public class, end users are discouraged to use this: please use Dataset.rdd instead where conversion will be applied.
