  • Well-known transactions in data replication
    Patent number: 7613751
    Abstract: A well-known transactions feature in data replication that takes the “last seen” transaction watermark, stores the watermark for each source in a topology, and tags each transaction with information associated with its origin. The tagged data is called Originator Information, and contains, but is not limited to, information on the originating server, originating database, and the originating transaction. This technology provides users with a method to scale out (keep more than two nodes in synchronism with updates at all nodes), increase availability of data during limited network failures (multiple replication pathways), and improve recovery strategies (redeliver transactions upon restore).
    Type: Grant
    Filed: October 12, 2006
    Date of Patent: November 3, 2009
    Assignee: Microsoft Corporation
