HBase is the NoSQL database of choice for Hadoop, and now supports critical real-time workloads in financial services and other industries. As HBase has grown more important for these workloads, the Hadoop community has focused on reducing potential down time in the event of region server failure. Rebuilding a region server can take 15 minutes or more, and even the latest improvements only provide timeline-consistent read access using standby region servers. In many critical applications, losing write access for more than a few seconds is simply unacceptable.
Enter Non-Stop for Apache HBase. Built on WANdisco’s patented active-active replication engine, WANdisco provides fully consistent active-active access to a set of replicated region servers. That means that your HBase data is always safe and accessible for read and write activity.
By providing fully consistent active-active replication for region servers, Non-Stop for Apache HBase gives applications always-on read/write access for HBase.
Putting a replica in a remote location also provides geographic redundancy. Unlike native HBase replication, region servers at other data centers are fully writable and guaranteed to be consistent. Non-Stop for Apache HBase includes active-active HBase masters, so full use of HBase can continue even if an entire cluster is lost.
Non-Stop for Apache HBase also simplifies the management of HBase, as you no longer need complicated asynchronous master-slave setups for backup and high availability.
Take a look at what Non-Stop for Apache HBase can do for your low-latency and real-time analysis applications.
