New features in MariaDB 10.3

Mature

Future Outlook

MariaDB 10.3 is ready to use in production. What's next? The MariaDB roadmap for version 10.4 [7] has two items on the agenda: security and Oracle compatibility. Furthermore, Kentoku Shiba seems to be continuing the development of his Spider storage engine.

In terms of InnoDB, the Instant ADD COLUMN is now followed by Instant DROP COLUMN; INVISIBLE does not seem to be enough. Like MySQL, MariaDB is also being write-optimized. Query parallelization and server-managed configuration (my.cnf) are also on the list. The people at MariaDB are unlikely to run out of ideas for what can be improved any time soon.

MariaDB 10.3 offers numerous new features that admins will want to test or use. Although the distributions deliver outdated MariaDB versions, MariaDB itself offers good repositories for all popular distros.
