Apache Cassandra is an open source, distributed database management system. It is designed to handle large amounts of data across many commodity servers. It provides high availability, with no single point of failure. Cassandra offers robust support for clusters spanning multiple data centers, with asynchronous masterless replication allowing low latency operation for all clients. It is extremely fault-tolerant because of its built-in replication features. It is also highly performant, decentralized, and most importantly, it's extremely durable for companies that cannot afford to lose any data.

Any distributed persistent application including Cassandra can have challenges. Let's understand few of those challenges that we face: complexity of installation; data movement expense and manual processes with node failures; performance limited by direct attached...
