MariaDB Xpand


MariaDB Xpand is a distributed SQL database with high availability, fault tolerance, and write scaling:

  • MariaDB Xpand supports ACID-compliant distributed SQL for modern web applications with massive workloads that require high performance and strong consistency, such as online transactional processing (OLTP).

  • MariaDB Xpand can adapt to changes in workload or capacity requirements with elastic scale-out and scale-in. When more capacity is required, more Xpand nodes can be added. When workload is reduced, Xpand nodes can be removed.

  • MariaDB Xpand provides efficient execution of complex queries (such as JOINs and aggregation operations) using parallel query execution.

  • MariaDB Xpand 6.0 adds support for Columnar indexes. Columnar indexes can improve the performance of workloads that can't benefit from row-based indexes, such as ad-hoc queries and operational analytics. Xpand can use row-based indexes and Columnar indexes on the same table, allowing these other workloads to be performed alongside a traditional OLTP workload.

MariaDB Xpand can be deployed in the cloud on MariaDB SkySQL, or on-premises.
