Abstract
A method, apparatus, and article of manufacture for optimizing database queries. The query is analyzed to determine whether at least a portion of the query can be evaluated using a plurality of parallel operations without data redistribution. If so, then the most efficient query execution plan that uses these parallel operations is constructed and executed.
