  36. def selectFilters(relation: BaseRelation, predicates: Seq[Expression]): (Seq[Expression], Seq[Filter])

    Selects Catalyst predicate Expressions which are convertible into data source Filters and can be handled by relation.

    Selects Catalyst predicate Expressions which are convertible into data source Filters and can be handled by relation.

    returns

    A pair of Seq[Expression] and Seq[Filter]. The first element contains all Catalyst predicate Expressions that are either not convertible or cannot be handled by relation. The second element contains all converted data source Filters that will be pushed down to the data source.
