Apache Cassandra™


Highly Available and Scalable Distributed Database

Apache Cassandra is a distributed database that delivers the high availability, performance, and linear scalability today’s most demanding applications require. It offers operational simplicity and effortless replication across cloud service providers, data centers, and geographies, and it can handle petabytes of information and thousands of concurrent operations per second across hybrid cloud environments.


The Untold Story of Apache Cassandra

Rebel NoSQL invader turned industry standard, Cassandra is the backbone of DataStax technology and the reason we love data management. Her history speaks volumes.

DataStax Commitment to Open Source Cassandra

From its inception, Cassandra has been the premier distributed database on the market, and here at DataStax, we remain committed to continuing that legacy. DataStax offers production-certified Cassandra distributions plus 24x7x365 expert support to ensure all Cassandra users can make the most of this powerful database.

#1 OSS Committer

DataStax has contributed a majority of the open source Cassandra code commits and we are one of the driving forces behind Apache Cassandra 4.0.

Apache Cassandra Experts

DataStax solutions are developed and updated from the open source Cassandra project, and the DataStax team has been an integral part of the Cassandra project since its inception.

Open Source Leadership

DataStax provides open source leadership in other database-related projects (like Apache TinkerPop™) as part of our commitment to open source.

No Compromises

When we’re not saving kittens from trees, DataStax is working hard to help you get the most from Cassandra without compromising on the value of the open source software.

Apache Cassandra™ Architecture

The data management needs of the average large organization have changed dramatically over the last ten years, requiring data architects, operators, designers, and developers to rethink the databases they use as their foundation. The proliferation of large-scale, globally distributed data led to the birth of Apache Cassandra™, one of the world’s most powerful and now most popular NoSQL databases. Read this white paper to learn how Cassandra was born, how it’s evolved, how it operates, and what DataStax Distribution of Apache Cassandra™ adds to the equation.


Apache Cassandra™ Architecture

"High availability is extremely important to us and our users, and that was the first thing that caught our eye with Apache Cassandra and DataStax. High availability with reliable performance is a big win for us."

Daniel Chia Software Engineer, Coursera

Advanced Database Capabilities

DataStax Enterprise (DSE) goes far beyond Apache Cassandra capabilities with double the horsepower, operational simplicity, and advanced security.

DSE Advanced Performance

DSE includes twice the horsepower of Apache Cassandra, delivering twice the throughput to handle twice the workloads with the same hardware. Plus DataStax Bulk Loader makes loading and unloading data a snap.

DSE NodeSync

A major challenge of Apache Cassandra is operational management. Repairing nodes for synchronization is an intensely manual process that requires the right expertise. DSE NodeSync removes that pain, eliminating 90% of such manual operations. So even novice DBAs and DevOps professionals can run DSE like seasoned professionals.

DSE Advanced Security

Apache Cassandra includes only basic security such as login and password. DSE adds comprehensive, enterprise-grade security, including authentication, authorization, transparent data encryption, JDBC drivers with built-in security, and auditing by user or profile.
