Abstract
A system and method for performing a query operation on a pair of relations in a database system coupled to a heterogeneous system (HS) is disclosed. Assuming that that pair of relations is partitioned and already loaded into the HS, the database system receives a query on the pair of relations and based on the type of query operation computes the cost of performing the query operation on the database alone or the costs of performing the query operation with the assistance of the HS, each of the costs corresponding to a particular algorithm. If the costs indicate that the HS improves the performance of the query operation, then the HS computes portions of the operation, and returns the results back to the database system. If any parts of the relation are out of sync with the database system, the database system performs operations to maintain transactional consistency.
