LocalJoin

case class LocalJoin(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 local hash join of two child relations. If a relation (out of a datasource) is already replicated accross all nodes then rather than doing a Broadcast join which can be expensive, this join just scans through the single partition of the replicated relation while streaming through the other relation
