Over the course of the last few months, Ralf and Josh have been on a journey, migrating the underlying databases of OpenStack from PostgreSQL to MariaDB.
In this presentation, they will talk about their migration story, starting from the reason why they embarked on the journey in the first place, and going into depth on some of the encounters they had with the beasts that lurk in the darker corners of a database.
Should you decide to embark on this perilous journey yourself, they have a long list of challenges that you should look out for such as the incompatibilities between both databases, as well as some of the operational hurdles to overcome.
Finally, they will introduce you to the open source tools they wrote to help ease the way for intrepid travellers. They will talk specifically about the case study of production OpenStack installations, but the tools they wrote can be applied generically, so you may use them as a roadmap for your own journey.
