Abstract
A replication occurs upon the re-configuration of a partial database to update an additional attribute of an object, and is divided into two sub-requests for replication. The first requests the new attribute from update sequence number zero and the second requests the existing attributes according to their known up-to-date vectors. To facilitate this request, a destination server sends an up-to-date vector table to a source server along with the request for replication. Because the existing attributes are requested from their known up-to-date vectors, rather than from update sequence number zero, this replication request results in less attributes being sent between servers and therefore, provides a more efficient replication.
