Innovation for the Community

MariaDB Community Server 10.6 adds major new features, including:

  • Extending JSON: JSON is fast becoming the standard format for data interchange and for unstructured data, and MariaDB (in fact, all MariaDB versions 10.2 and later) includes a range of JSON supporting functions. With this release, MariaDB adds JSON table functions, enabling a table view into JSON data stored in MariaDB. Queries are returned as a regular table using SQL.
  • Oracle compatibility: Beginning with version 10.3, MariaDB was the first open source database to add PL/SQL compatibility, making it easy to migrate from Oracle to MariaDB. This release adds several new community-developed PL/SQL compatibility functions, a reflection of the wide-reaching impact this open source innovation has had in the world.
  • Atomic DDL: With MariaDB Community Server 10.6, Data Definition Language (DDL) is now atomic, increasing crash recovery by ensuring any DDL statement is either fully executed or not at all. Unlike MySQL, MariaDB implemented atomic DDL in the database layer so it supports various workloads using different storage engines, with immediate support for InnoDB and Aria storage engines. Atomic DDL support for other storage engines is coming soon.
  • Analytics: Last year, columnar analytics was added as a supported storage engine for MariaDB, delivering analytics for all. Unlike MySQL, analytics in MariaDB is open source and can be deployed anywhere. MariaDB Community Server 10.6 includes significant enhancements to its analytical capabilities including performance improvements, additional Oracle compatibility, better resiliency and new disk-based aggregation to support larger aggregate data sets and lower hardware costs.


The general availability of MariaDB Community Server 10.6 is available for free direct download at in early July. For customers interested in MariaDB for production environments with built-in high availability, please contact MariaDB for early access to MariaDB Enterprise Server 10.6.
