    <p>Allows basic access to a Cassandra database.</p>
    <p>This node uses the <b>query</b> operation against the configured database. This does allow  SELECTS, INSERTS, UPDATES and DELETES.</p>
    <p><code>msg.topic</code> must either hold the <i>query</i> (string) for the database or an array of <i>queries</i> (which triggers a batch execution),
    and the result is returned in <code>msg.payload</code>.</p>
    <p><code>msg.payload</code> can contain an optional array of values to bind to the topic.</p>
    <p>Typically the returned payload will be an array of the result rows.</p>
    <p>If nothing is found for the key then <i>null</i> is returned,</p>
