title: How to add multiple columns in cassandra table?
body: <p>I need to add some <code>new columns</code> to my <code>existing column_family/table</code> in cassandra.
  I can add single column like this :</p>
  
  <pre><code>ALTER TABLE keyspace_name.table_name ADD column_name cql_type;
  </code></pre>
  
  <p>Can I add all new columns using a single query? If yes, how to do it using <code>cql</code> and <code>datastax cassandra driver</code>?</p>
