Cassandra: Scalable & Fault-Tolerant NoSQL Database

Cassandra is a distributed, open-source NoSQL database management system designed to handle large amounts of data across multiple commodity servers. It was developed by Facebook and is now maintained by the Apache Software Foundation. Cassandra is highly scalable and fault-tolerant, allowing it to handle petabytes of data with high availability and low latency. It uses a distributed architecture with no single point of failure, making it suitable for use in mission-critical applications that require high levels of performance and reliability. Cassandra is widely used in industries such as finance, healthcare, gaming, and social media.
