[Openstack] [Trove] Relational or Non-relational DB?

Hi Giuesppe,
The mission statement for trove was recently changed and approved by the technical committee to include both relational and non-relational databases.   There are several blueprints in place for non-relational data stores with some implementation work also in flight.

Subject: [Openstack] [Trove] Relational or Non-relational DB?

Dear all,
I am a developer interested to the Databases as a Service, and in particular for creation of relational and non-relational databases. So I joined the Trove project.

On this link (https://wiki.openstack.org/wiki/Trove#Mission_Statement) I read: "Mission of Trove: to provide scalable and reliable Cloud Database as a Service provisioning functionality for both relational and non-relational database engines.

On this link (http://docs.openstack.org/developer/trove/#introduction), instead, I read: "It’s designed to run entirely on OpenStack, with the goal of allowing users to quickly and easily utilize the features of a relational database"

So, I am confused.

1) Is Trove designed to create both a relational and a non-relational database?

2) Is Trove designed to create only a relational database?  In this case, how can I modify the source code in order to allow creation of relational databases that use no-mysql engine (but use, for example, Postegres)?

Thank you very much,
