Hey guys I know that using the Doctrinebundle in Symfony2 it is possible to instantiate multiple DB connections under Doctrine...

$connectionFactory = $this->container->get('doctrine.dbal.connection_factory');
$connection = $connectionFactory->createConnection(array(
    'driver'   => 'pdo_mysql',
    'user'     => 'foo_user',
    'password' => 'foo_pass',
    'host'     => 'foo_host',
    'dbname'   => 'foo_db',
));

I'm curious if this is the case if you are using PURELY Doctrine though?, I've set up Doctrine via Composer like so...

{
    "config": {
        "vendor-dir": "lib/"
    },
    "require": {
        "doctrine/orm": "2.3.4",
        "doctrine/dbal": "2.3.4"
    }
}

And have been looking for my ConnectionFactory class but am not seeing it anywhere? Am I required to use Symfony2 to do this? Thanks!
