MariaDB

MariaDB in Pukki is still in beta

This means that it hasn't been tested as extensively as PostgreSQL, and there might still be large changes to how Pukki manages MariaDB database instances.

Database engine and backups

MariaDB database instances on Pukki use InnoDB by default, as most testing has been done using it. Changing to other engines such as Aria might cause issues with backups, so one should carefully consider how necessary it is before switching from InnoDB. More information on database engines can be found in the official MariaDB documentation.
