Percona XtraDB Cluster / Galera in Practice (6 hour tutorial):
I've been working on this tutorial since last summer. The first incarnation was at Percona Live NY last year, but I've altered it quite a bit and expanded to fit (hopefully) a 6 hour format. Expect a lot of down and dirty hands-on work with setting up, managing and monitoring PXC. MariaDB Galera Cluster users should fit right in:

We also started beta support for Percona XtraDB Cluster in 2.1.8, but now that support is official in 2.2 because we have had many months to work with PXC and figure out which tools work with it and how. There's still one noticeable omission: pt-table-sync. It's still unclear if or how one would sync a cluster that, in theory, doesn't become out-of-sync. As Percona XtraDB Cluster develops, Percona Toolkit will continue to evolve to support it.

InnoDB monitor was prefetching the data pages for printing lock information even if no lock information was going to be printed. Bug fixed # 1100643 ( Laurynas Biveinis ).

I was curious to check how Percona XtraDB Cluster behaves when it comes to MySQL replication latency — or better yet, call it data propagation latency. It was interesting to see whenever I can get stale data reads from other cluster nodes after write performed to some specific node. To test it I wrote quite a simple script (you can find it in the end of the post) which connects to one node in the cluster, performs an update and then immediately does the read from second node.
