Log-based database replication provides a way to deliver the data needed to power real-time analytics without the performance problems and complexity issues associated with traditional approaches. Because these real-time analytics are so much in demand for many business and government organizations, we have developed our database replication software to support this approach.
HVR supports log-based change data capture out of most commonly used databases to enable real-time updates with minimal system impact. On a well-configured system, HVR captures data from the source as soon as it is committed to the online transaction log.
At the destination, HVR ensures scalability for large volumes of data for any target database through optimizations such as burst mode, coalescing changes, and the ability to combine transactions.
