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

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.

    Overridden by concrete implementations of SparkPlan.

    Overridden by concrete implementations of SparkPlan. It is guaranteed to run before any execute of SparkPlan. This is helpful if we want to set up some state before executing the query, e.g., BroadcastHashJoin uses it to broadcast asynchronously.

    Note: the prepare method has already walked down the tree, so the implementation doesn't need to call children's prepare methods.
