There are certain MySQL that optimize its performance with an RBD pool that has also been specifically configured for use with a database. We need a template wish pushes out a MySQL instance to the correct pool with the right MySQL settings.
Based on customer feedback, and the constant message that support for commercially available database was an absolute must from the almost all of the customers we surveyed, we have came to the conclusion that we should rather concentrate our effort in having successful partnerships around Trove rather than building a fully open-source solution that will not benefit our customers.
