  10. def canEvaluate(expr: Expression, plan: LogicalPlan): Boolean

    Returns true if expr can be evaluated using only the output of plan.

    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

    Returns a filter that its reference is a subset of outputSet and it contains the maximum constraints from condition. This is used for predicate pushdown. When there is no such filter, None is returned.

[SPARK-32290] LeftAnti(condition: Or(EqualTo(a=b), IsNull(EqualTo(a=b))) will almost certainly be planned as a Broadcast Nested Loop join, which is very time consuming because it's an O(M*N) calculation. But if it's a single column case O(M*N) calculation could be optimized into O(M) using hash lookup instead of loop lookup.
