Ohyes, and Open Query does MySQL magic for you: remote support/DBA, OQGRAPH engine.... but Arjen would like you too to enjoy your free time, so he and his gang help you design well and prevent trouble, rather than play "fire department".

Multi-Master MySQL
Implementing multi-master setups with MySQL is fairly trivial in basic terms, but for an effective environment much more is involved. There are some tools (such as MMM, Multi-Master MySQL Manager) that can help, but there's still a lot to think of and each deployment is different.
So why would you wish to bother, given all these complications? This session will discuss precisely that, as well as the tools and pitfalls.
Easy and Fast Tree/Graph Traversal and Social Networking in Drupal
Everybody knows that dealing with hierarchies in a relational database is awkward, and depending on your needs it gets ugly, or downright impossible to do quickly in SQL (lots of queries needed, etc).
What if...
- you could do such operations with simple single queries?
- you could have not only simple trees but also complex ones (multiple parents) ?
- you could have complex graphs for friend-of-a-friend or other structures?
