What is Apache Cassandra?

Apache Cassandra is a highly scalable, distributed NoSQL database designed to handle large amounts of data across many commodity servers with no single point of failure. Originally developed at Facebook and open-sourced in 2008, Cassandra provides linear scalability and proven fault-tolerance on commodity hardware.

Cassandra uses a distributed architecture where every node in the cluster has the same role, eliminating single points of failure. It offers robust support for clusters spanning multiple data centers with asynchronous masterless replication, allowing for lower latency and protection against regional failures.

Built for write-heavy workloads, Cassandra excels at handling time-series data, IoT sensors, messaging systems, and any application requiring continuous availability. Its column-family data model and tunable consistency levels make it ideal for applications that can trade consistency for availability and partition tolerance.
