VoltDB is an in-memory, scale-out, SQL operational database for high-performance, fast data applications. VoltDB enables developers to build high volume data pipelines by combining the capabilities of an operational database, real-time analytics, and stream processing in one easy-to-use platform.

When used with Hadoop, VoltDB has the ability to export data at high speed to long-term Hadoop-based analytics stores, providing an end-to-end solution that combines the long-term, deep analytics capability of Hadoop with the speed, and operational capability of in-memory analytics. VoltDB enables data to arrive in your analytic store sooner, and allows deep analytics to be leveraged with radically lower latency.
