I do not think this is the most optimal way to get the connection type. The database key can be any arbitrary value.

What about getting it from the queryBuilder, something like $queryBuilder->getConnection()->getDriverName(). I just quickly looked it up, so I am not 100% sure it is a viable option - could you look into it? :-)
