case class RangePartitionId(child: Expression, numPartitions: Int) extends UnaryExpression with Unevaluable with Product with Serializable

Unevaluable placeholder expression to be rewritten by the optimizer into PartitionerExpr

This is just a convenient way to introduce the former, without the need to manually construct the RangePartitioner beforehand, which requires an RDD to be sampled in order to determine range partition boundaries. The optimizer rule will take care of all that.
