title: Dynamodb return all results sorted
body: <p>I've got a simply dynamodb model: </p>
  
  <pre><code>id (partition key), timestamp_id (sort key)
  </code></pre>
  
  <p>All I simply want is to get all the data out of dynamo (using limit and such) but sorted by <code>timestamp_id</code>. A scan unfortunately doesn't return sorted data, and it seems I can't have an empty query, unless I'm missing something.</p>
