Highly Available and Scalable Distributed Database

Apache Cassandra™ is a distributed database that delivers the high availability, performance, and linear scalability that today’s most demanding applications require. It is the database of choice for high growth applications that span across cloud service providers, data centers, and geographies. The Apache Cassandra ecosystem delivers the integrations, management, and developer tooling you expect from the leading scale out NoSQL database.

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.

Apache Cassandra Support

DataStax Luna provides subscription-based support for open source Cassandra to help ensure you meet required service levels while providing your team with the confidence they need to deploy and run their applications.

  • Get support directly from the distributed database experts who authored a majority of the Cassandra code, drivers, and tools.
  • Choose the right level of support for your budget as well as your technical and business needs then easily scale through the self-service portal.
  • Get started in minutes through a simple process that lets you begin coverage directly through our website.

5 Steps to an Awesome Apache Cassandra™ Data Model

"As more customers adopt digital channels over traditional brick and mortar stores and call center channels, there is a need to handle high traffic volume fluctuations, and ability to scale dynamically in a cost-efficient way. This is a common challenge faced across the industry. Verizon solved this challenge for its wireless OSS/BSS stack using DSE Cassandra and Spark. DSE enabled Verizon to transform its OSS/BSS platform from a legacy mainframe-based monolithic stack to a highly scalable cloud-enabled stack. This new platform enables better customer experience through high availability and scalability. Verizon was the only major wireless provider that was able to handle the Apple iPhone pre-order volume spike, and was available to take customer orders at 3 a.m. ET when the floodgates were opened. DSE migration addresses the economic scalability and low latency needs of 5G and IoT. In addition to the enhanced customer experience, the DSE migration eliminated 90% of operations cost. Migration of a large-scale application presents unique challenges that are not encountered in green field development. This presentation focuses on the challenges faced in adopting Cassandra for transactional data that is migrated from traditional RDBMS/mainframe. The presentation will cover details on the data model, data ingestion, and data reconciliation techniques that enables digital transformation."

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.

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.
