The 2015 MariaDB Developers meetup is taking place in Amsterdam, from October 13th to 15th. Anyone who is interested in contributing to the MariaDB project is welcome to join!
The event will be held in unconference style with lots of opportunities for discussions and collaboration around any topic, ranging from performance, new features, connectors to packaging and documentation. All core MariaDB developers will be present and available for discussions.
The meetup lasts for three days and you can join for the whole time, or as little time as you wish.
