To use this Apache Druid extension, make sure to [include](../../development/extensions.md#loading-extensions) `druid-cassandra-storage` extension.
[Apache Cassandra](http://www.datastax.com/what-we-offer/products-services/datastax-enterprise/apache-cassandra) can also
be leveraged for deep storage. This requires some additional Druid configuration as well as setting up the necessary
schema within a Cassandra keystore.
