TakeOrdered

case class TakeOrdered(limit: Int, sortOrder: Seq[SortOrder], child: SparkPlan)(sqlContext: SQLContext) extends SparkPlan with UnaryNode with Product with Serializable

:: DeveloperApi :: Take the first limit elements as defined by the sortOrder. This is logically equivalent to having a Limit operator after a Sort operator. This could have been named TopK, but Spark's top operator does the opposite in ordering so we name it TakeOrdered to avoid confusion.
