What Is Cassandra & Why Use It

Cassandra is an open-source, distributed, wide-column NoSQL database management system written in Java. Cassandra was originally developed by Avinash Lakshmanan and Prashant Malik at Facebook and then released as open source, eventually becoming part of the Apache project.
