Abstract
A method of performing a database join includes receiving a query. The query may specify a join of a first table and a second table. The method further includes determining a new predicate based on a mapping between a first column of the first table and a second column of the second table for a plurality of tuples of the join. Further, the method includes modifying the query such that the query comprises the new predicate.
