If the join filter cannot be satisfied (for example, if it is l.c1 > r.c2
and the
join only supports equi-join), removes the filter from joinFilters
and adds it to
aboveFilters
.
The default implementation does nothing; i.e. the join can handle all conditions.
aboveFilters
- Filter above JoinjoinFilters
- Filters in join conditionjoin
- JoinjoinType
- JoinRelType could be different from type in Join due to outer join
