TopKTransformer

class TopKTransformer[B] extends Transformer with DefaultParamsWritable with HasGroupByColumns

Created by eugeny.malyutin on 20.07.17.

Performs TopK-UDAF logic without annoying schema pack-unpack

B

- raw type (Long for LongTyped-columns) for columnToOrderBy Ordering for this type should be defined
