Hi,
I have installed Maria DB to all my servers, including production servers few weeks ago, and I found it quite stable and I like it (even the command line tool for working with sql is far better than the one included in mysql pack)
It's supported on all latest ubuntu versions from 10.04 UP (maybe even older) - so my question is, are we going to use it on wikimedia production?
I think we could migrate beta cluster for now - it has terrible performance and this could help. It could be a first step to migrate wikimedia production cluster.
