  • ITEM-SET KNOWLEDGE FOR PARTIAL REPLICA SYNCHRONIZATION
    Publication number: 20080294701
    Abstract: A system is disclosed for synchronizing partially-replicated collections while keeping synchronization overhead low by using the concept of item-set knowledge. Item-set knowledge uses knowledge fragments, which associate knowledge vectors with item-sets. An item-set consists of an explicitly represented list of items. In a partial replica, this item set may be the items known to a replica within which a filter is applied limiting the items known to some subset of the overall items in the collection.

  • WEAKLY-CONSISTENT DISTRIBUTED COLLECTION COMPROMISED REPLICA RECOVERY
    Publication number: 20080162589
    Abstract: A system is disclosed for recovery from a compromise of a replica in a weakly-consistent distributed collection. The system employs a collection manager for revoking a compromised replica, and one or more archival replicas for storing time-stamped versions. Upon a compromise, versions tainted by the compromised replica may be expunged from the collection. Thereafter, versions determined to be unaffected by the compromise may be returned to the collection using the time-stamped versions stored in the one or more archival replicas.
