Warning!

Puhti and Mahti are being decommissioned in stages, and their storage areas will become fully unavailable from 15 October 2026. Clean up unnecessary files and move any data you need to keep by 31 August 2026. See the Roihu data migration guide for instructions on transferring your data to Roihu.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

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.
