MySQL on Mesos: today's database meets tomorrow's datacenter

From what I gathered, the main reason people would want to move over to MariaDB is a concern over the Oracle licensing of MySQL, which prompted some of the original MySQL developers to create the MariaDB community fork.
I'm asking this question more from a greenfield perspective rather than as a continuation/expansion of an existing MySQL deployment.
