TreeRegionJoin

trait TreeRegionJoin[T, U, RT, RU] extends RegionJoin[T, U, RT, RU]

Implements a shuffle free (broadcast) region join.

The broadcast values are stored in a sorted array. It was going to be an ensemble of interval trees, but, that didn't work out.

Abstract Value Members

  1. abstract def partitionAndJoin(baseRDD: RDD[(ReferenceRegion, T)], joinedRDD: RDD[(ReferenceRegion, U)]): RDD[(RT, RU)]

    Performs a region join between two RDDs.

    Performs a region join between two RDDs.

    baseRDD

    The 'left' side of the join

    joinedRDD

    The 'right' side of the join

    returns

    An RDD of pairs (x, y), where x is from baseRDD, y is from joinedRDD, and the region corresponding to x overlaps the region corresponding to y.
