# ShuffleRegionJoin 

###

#### sealed abstract class ShuffleRegionJoin[T, U, RT, RU] extends RegionJoin[T, U, RT, RU]

A trait describing join implementations that are based on a sort-merge join.

T

  The type of the left RDD.

U

  The type of the right RDD.

RT

  The type of data yielded by the left RDD at the output of the join. This may not match T if the join is an outer join, etc.

RU

  The type of data yielded by the right RDD at the output of the join.
