title: How would I add cassandra support for symfony/doctrine?
body: <p>I want to use Cassandra with Symfony. It is my first time using both technologies. I have conducted a lot of research into what has already been done, and it seems like there is no support for Cassandra from within Symfony (which uses Doctrine ORM). How difficult would it be for me to extend Doctrine to include support for Cassandra? What would be the best, cleanest, and most upgradable way to include this functionality?</p>
