> 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.
