Transparent fault detection and recovery - nodes that fail can easily be restored or replaced.
Continuous availability - offers redundancy of both data and node function, which eliminate single points of failure and provide constant uptime.
Linear scale performance - the ability to add nodes without going down produces predictable increases in performance.
Active everywhere design - all nodes may be written to and read from.
Massively scalable architecture - a masterless design where all nodes are the same, which provides operational simplicity and easy scale-out.
Key Features and Benefits of Cassandra Database Cassandra was originally developed at Facebook, was open sourced in 2008, and became a top-level Apache project in 2010. Apache Cassandra (Cassandra DB) is a free and open-source distributed wide column store NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
