| To use this Apache Druid extension, [include](../../configuration/extensions.md#loading-extensions) `druid-cassandra-storage` in the extensions load list. |
| |
| [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. |
