phpcassa has been deprecated and so is this bundle. If you want to integrate newer versions of Cassandra in your PHP/Symfony projects please check out the new PHP driver located here: https://github.com/datastax/php-driver (supporting CQL and many other goods) and a new Cassandra bundle using it located here: https://github.com/M6Web/CassandraBundle
This bundle integrates phpcassa into your Symfony2 application.
This bundle is also available via composer, find it on packagist.
