  • object PushLeftSemiLeftAntiThroughJoin extends Rule[LogicalPlan] with PredicateHelper

    This rule is a variant of PushPredicateThroughJoin which can handle pushing down Left semi and Left Anti joins below a join operator.

    This rule is a variant of PushPredicateThroughJoin which can handle pushing down Left semi and Left Anti joins below a join operator. The allowable join types are: 1) Inner 2) Cross 3) LeftOuter 4) RightOuter

    TODO: Currently this rule can push down the left semi or left anti joins to either left or right leg of the child join. This matches the behaviour of PushPredicateThroughJoin when the lefi semi or left anti join is in expression form. We need to explore the possibility to push the left semi/anti joins to both legs of join if the join condition refers to both left and right legs of the child join.

object PushdownDirection extends Enumeration

Define an enumeration to identify whether a LeftSemi/LeftAnti join can be pushed down to the left leg or the right leg of the join.
