MariaDB Developers meeting 2015 is taking place in Amsterdam. The whole core MariaDB development team will be present to discuss and plan MariaDB going forward.
The meeting lasts for three days and you can join for which ever day you want. Also, you don't have to be a MariaDB or MySQL database server developer to join.
Everyone working with MariaDB and/or MySQL or any of the other forks are more than welcome!
There will be discussions around the community aspects as well as for documentation and infrastructure of the MariaDB project etc. Also MaxScale and the core team developing it will be present.
