Also this year we will have a special track for MySQL, Galera, Percona und MariaDB at the FrOSCon in St. Augustin in Germany. The conference is scheduled for August 25 and 26 2012.
Together with the PostgreSQL people we are organizing a sub-conference for Open Source RDBMS there. Now we are looking for interesting talks about MySQL and related techniques like Galera, Percona, MariaDB. The only restriction for the talks is: They must be about an Open Source topic.
