Amazon RDS for MariaDB now supports MariaDB major version 11.8, the latest long-term maintenance release from the MariaDB community. This release supports MariaDB 11.8.3 minor version.

Amazon RDS for MariaDB 11.8 now supports the MariaDB Vector feature, allowing you to store vector embeddings in your database and use retrieval-augmented generation (RAG) when building your Artificial Intelligence (AI) applications. You can use MariaDB Vector to build generative AI capabilities into your e-commerce, media, health applications, and more to find similar items within a catalog. MariaDB 11.8 also introduces the ability to limit maximum size of temporary files and tables, allowing you to better manage your databases’ storage and prevent potential issues caused by oversized temporary objects. Learn more about these community enhancements in the MariaDB 11.8 release notes and RDS MariaDB release notes.

You can initiate a major version upgrade by manually modifying your DB cluster, by restoring a snapshot or by leveraging Amazon RDS Managed Blue/Green deployments to upgrade your databases to RDS for MariaDB 11.8. Learn more about upgrading your database instances in the Amazon RDS User Guide. Amazon RDS for MariaDB 11.8 is available in all AWS regions where RDS MariaDB is available.
