.impossible_objects ⇒ Object

impossible_objects keep the class to objects relationships that the objects may not cause N+1 query. e.g. { Post => [“Post:1”, “Post:2”] } if find collection returns only one object, then the object is impossible object, impossible_objects are used to avoid treating 1+1 query to N+1 query.
