Per discussion on the PR, I believe that this is "Won't Fix" for 1.x?

> Now in {{DataSourceStrategy}}, the pushdown predicates are duplicate of original {{Filter}} conditions. Thus, some predicates are performed both by data source relation and {{Filter}} plan. I think it is a duplicate loading. Once the predicates are pushed down and performed by a data source relation, it
> can be eliminated from outside {{Filter}} plan's condition.
