Clustrix is the leading scale-out SQL relational database engineered for the cloud.
The Clustrix scale-out SQL relational database disproves the notion that a relational database can’t scale to large transactional workloads with billions of rows of data. Outperforming alternatives such as NoSQL while keeping the benefits of ACID and relations, Clustrix achieves high performance by scaling horizontally across blade servers, with linear performance improvement each time a new node is added to the cluster.
Clustrix is compatible with the MySQL protocol, making it a drop-in replacement for existing MySQL implementations that don’t scale and require complex interventions such as sharding. To the application, Clustrix simply appears as a single-instance database that can scale incrementally to whatever size is needed. Delivering on the promise of simplicity, the Clustrix database is available in the cloud, on-premise as an appliance or on AWS Marketplace, allowing organizations to start within minutes and scale.
While scale and performance receive the most headlines, database resiliency is often the most important factor for critical applications. Clustrix utilizes data reprotection functionality to ensure all business-critical data is safe and available. If a flash drive or even an entire node fails, you know both your database and application remain available and fully operational. And this happens with zero downtime, ensuring your business doesn’t take a hit.
Clustrix has extended the SQL query language to make development ultra flexible. Our extended SQL combines the benefits and simplicity of a JSON document interface with the power and flexibility of SQL. This enables applications to store data in the most relevant formats and facilitates Agile development as well as real-time schema changes.
Clustrix incorporates revolutionary SQL relational database technology
Distributed relational database architecture for scale-out transactional performance
Clustrix provides a unique parallel query approach that generates distributed query plans and query fragments for speed and scale.

Seamless workload and capacity expansion
Clustrix is the only provider of linear scale for a relational data store. Simply add more nodes when it comes time to scale, and never worry about limits. Now, achieve all the scale you need without ever having to cope with cost and complexity of sharding.

Linear scale as proven in the Percona TPCC Performance Paper
