Abstract
A method, storage server, and computer readable medium for off-loading star-join operations from a host information processing system to a storage server. At least a first and second set of keys from a first and second dimension table, respectively are received from a host system. Each of the first and second set of keys is associated with at least one fact table. A set of locations associated with a set of foreign key indexes are received from the host system. A set of fact table indexes are traversed. At least a first set of Row Identifiers (“RIDs”) associated with the first set of keys and at least a second set of RIDs associated with the second set of keys are identified. An operation is performed on the first and second sets of RIDs to identify an intersecting set of RIDs. The intersecting set of RIDs are then stored.
