    The attribute name may differ from the one in the schema if the query analyzer is case insensitive.

    The attribute name may differ from the one in the schema if the query analyzer is case insensitive. We should change attribute names to match the ones in the schema, so we do not need to worry about case sensitivity anymore.

  46. 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.

    Tries to translate a Catalyst Expression into data source Filter.

    returns

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

  52. def translateFilterWithMapping(predicate: Expression, translatedFilterToExpr: Option[HashMap[Filter, Expression]], nestedPredicatePushdownEnabled: Boolean): Option[Filter]

    Tries to translate a Catalyst Expression into data source Filter.

    Tries to translate a Catalyst Expression into data source Filter.

    predicate

    The input Expression to be translated as Filter

    translatedFilterToExpr

    An optional map from leaf node filter expressions to its translated Filter. The map is used for rebuilding Expression from Filter.

    nestedPredicatePushdownEnabled

    Whether nested predicate pushdown is enabled.

    returns

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