  • Routing replicated data based on the content of the data
    Patent number: 10198493
    Abstract: Disclosed herein are system, method, and computer program product embodiments for routing data to be replicated based on the content of the data. An embodiment operates by retrieving a row from a database transaction log receiving a filtering condition. The embodiment evaluates whether the content of the row satisfies the filtering condition and selects a replication path for transmitting the transaction for replication.
    Type: Grant

  • Multi-Path Replication in Databases
    Publication number: 20150046400
    Abstract: Systems, methods and computer program products for multi-path replication in databases are described herein. A non-limiting embodiment includes instantiating a plurality of replicate connections to a replicate database, providing transactions to the replicate database through a plurality of transaction streams, where the transaction streams associated with respective instantiated replicate connections. Transactions occurring in distinct transaction streams are applied, in parallel, at the replicate database. Another non-limiting embodiment includes instantiating a plurality of replication sender threads, where the replication sender threads communicate in parallel with respective replication servers over respective replication paths. Data sharing one or more attributes can be bound to a replication path in communication with the respective replication servers.
