An introduction to Apache Cassandra®

Apache Cassandra is an open-source, NoSQL, wide column data store that can quickly ingest and process massive amounts of data. It's decentralized, distributed, scalable, highly available, fault-tolerant and tuneably consistent, with identical nodes clustered together to eliminate single points of failure and bottlenecks. Cassandra is used today by CERN, GitHub, Apple, Netflix, and countless other organizations for managing large amounts of semi-variable but structured data (from sensors, connected appliances and applications) for analytics, event logging, monitoring, and eCommerce purposes, particularly when high write speeds are needed.
