We have noted no percona specific problems, except for percona being a little bit faster than mysql 5.5. It wouldn't be hard to add mariadb to the upgrade cycle if people were interested in that.

All of the tempest tests run on Ubuntu Precise with most jobs using MySQL and a few using PostgreSQL. None of the tests use MariaDB today. There were folks working on getting Fedora nodes into nodepool to do testing of some sort on Fedora (which would be MariaDB aiui), but ran into trouble around nodepool's privilege expectations (something about sudo needing a proper tty and paramiko not being able to nicely provide one). We should pick that work back up again, but Infra has been swamped recently. If we do end up adding MariaDB integration (tempest) tests I would not add another set of tests. Instead we should probably swap out MySQL and use MariaDB in one of the existing tests.

Re: [openstack-dev] MariaDB support
This is exactly my worry... at what point can I consider moving to MariaDB with the expectation that the testing confidence is equivalent to that which is currently available from MySQL ? The on-disk format is not so much a concern but there are many potential subtle differences in the API which can occur over time such as reserved words or recovery handling from certain errors. Currently, my 'operational' hat says stay with MySQL. My 'community' hat direction is less clear. Given that Ubuntu and Red Hat are not agreeing on the direction makes this likely to be an extended uncertainty. Maybe two yes/no answers would help 1. Is there any current blocking gate tests with MariaDB ? 2. Is there a plan to change this at a future release ? If the answer to 1 is no, the operational hat says to stay on MySQL currently. If the answer to 2 is yes, we should be planning to migrate.

On-disk format changes are completely opaque to OpenStack testing. That comes with MariaDB 10 as they basically have decided to stop trying to keep up with the Oracle firehose of engineering changes and go their own way. We would only care about that change if we wanted to have drop-in replacement capability to test between the two. For OpenStack, only SQL or protocol incompatibilities would matter. IMO MariaDB would be wise to be very careful not to ever break this. That is one of the things that really trashed early adoption of Drizzle IMO, because you had to change your app to speak Drizzle-SQL instead of just speaking the same old (broken) MySQL. Us using the more strict traditional dialect will hopefully save us from the fate of having to adapt to different forks of MySQL though. ___ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
