What's new in this release?

  • MariaDB Platform for Scale-Out Transactions allows you to deploy 3-7 nodes of MariaDB Enterprise Server 10.5 with the Xpand storage engine for Distributed SQL, enabling the distribution of the entire database or just individual tables.

  • MariaDB Enterprise Server 10.5 and MariaDB Enterprise Server 10.4 are now available for MariaDB Platform for Transactions.

  • Configuration Manager support has been extended to all services (previously transactional-only), with an expanded set of configurable options. Additionally, Configuration Manager now provides the ability to configure the MaxScale load balancer in Primary/Replica configurations of MariaDB Platform for Transactions.

  • Workload Analysis technical preview, previously a feature demonstration, has been updated to collect monitoring data of your SkySQL transaction services, when enabled. The data is then analyzed to characterize the workloads running on the database and provide insights beyond what traditional monitoring allows.
