  34. def selectFilters(relation: BaseRelation, predicates: Seq[Expression]): (Seq[Expression], Seq[Filter], Set[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 triplet of Seq[Expression], Seq[Filter], 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. The third element contains all Filters that are completely filtered at the DataSource.

    Tries to translate a Catalyst Expression into data source Filter.

    returns

    a Some[Filter] if the input Expression is convertible, otherwise a None.
