Apache Cassandra is a NoSQL database written in Java and designed for reliability and high scalability. Because it is built in Java it is also subject to the limitations and performance hiccups associated with traditional JVMs. Common issues include response time outliers, frequent Java garbage collections, out of memory errors and system hangs. Companies deploying Cassandra spend extensive time tuning and tweaking the JVM to avoid these issues.
The Azul Zing runtime allows Cassandra to run smoothly, free of Java-related performance glitches and hangs. Zing removes garbage collection as an issue; your deployment can now have consistent response times at all times, without GC pauses, node hangs or out of memory errors, regardless of load or object allocation rates.
