VoltDB is in production in clusters of one to 30 nodes. We’ve successfully tested VoltDB in clusters of about 100 nodes. Many have asked us about 1,000 node clusters and why that’s not our goal. We believe clusters under 100 nodes offer a solid balance between performance, fault-tolerance and manageability.
There are a few applications with throughput requirements that require more than a small VoltDB cluster. Because VoltDB is often one or two orders of magnitude faster per node than competing systems, VoltDB clusters are ready for your workload, whether it’s hundreds of operations per second or millions.
