Apache Cassandra


Apache Cassandra is a non-relational distributed database with a fault-tolerant leaderless architecture.

Cassandra scales to petabytes of storage and millions of queries per second in a single database, provides real-time multi-region replication, and supports atomic transactions. Cassandra’s architecture is resilient to failure, enabling the database to survive the loss of individual machines and entire datacenters. Its leaderless design also simplifies deployment and eliminates single points of failure.

With thousands of companies using Cassandra, the user community has developed a rich client ecosystem with support for Java, Python, Swift, C++, Go, Rust, JavaScript, C#, Ruby, and other languages; as well as tooling that simplifies operation.
