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).
