description Overview

Cassandra

Apache Cassandra is a distributed NoSQL database designed to handle massive amounts of data across many commodity servers. It uses a peer-to-peer architecture, meaning there is no single point of failure. It is optimized for high-velocity writes and provides linear scalability, making it the go-to choice for global applications that require constant uptime and rapid data ingestion.

MongoDB
