BroadcastHashJoin

case class BroadcastHashJoin(leftKeys: Seq[Expression], rightKeys: Seq[Expression], buildSide: BuildSide, left: SparkPlan, right: SparkPlan) extends SparkPlan with BinaryNode with HashJoin with Product with Serializable

:: DeveloperApi :: Performs an inner hash join of two child relations. When the output RDD of this operator is being constructed, a Spark job is asynchronously started to calculate the values for the broadcasted relation. This data is then placed in a Spark broadcast variable. The streamed relation is not shuffled.
