PushDownLeftSemiAntiJoin

object PushDownLeftSemiAntiJoin extends Rule[LogicalPlan] with PredicateHelper with JoinSelectionHelper

This rule is a variant of PushPredicateThroughNonJoin which can handle pushing down Left semi and Left Anti joins below the following operators. 1) Project 2) Window 3) Union 4) Aggregate 5) Other permissible unary operators. please see PushPredicateThroughNonJoin.canPushThrough.

    Builds a balanced output predicate in bottom up approach, by applying binary operator op pair by pair on input predicates exprs recursively.

    Builds a balanced output predicate in bottom up approach, by applying binary operator op pair by pair on input predicates exprs recursively. Example: exprs = [a, b, c, d], op = And, returns (a And b) And (c And d) exprs = [a, b, c, d, e, f], op = And, returns ((a And b) And (c And d)) And (e And f)

    Returns true if expr can be evaluated using only the output of plan. This method can be used to determine when it is acceptable to move expression evaluation within a query plan.

    For example consider a join between two relations R(a, b) and S(c, d).

    - canEvaluate(EqualTo(a,b), R) returns true - canEvaluate(EqualTo(a,c), R) returns false - canEvaluate(Literal(1), R) returns true as literals CAN be evaluated on any plan

    If the outer alias has explicit metadata, it is preserved. Else if the inner alias has explicit metadata, the result has explicit outer.metadata. Else both are deriving the metadata. the result is deriving metadata, with the union of noninheritable keys.
