title: How to use AWS Dynamodb to store session-like data?
body: <p>I saved the sample data structure listed below to dynamoDB.</p>
  
  <pre><code>{
   id: 'uuid',
   data: 'data',
   lastModifiedTime: 'Fri Feb 26 2016 16:22:29 GMT+0800 (CST)'
  }
  </code></pre>
  
  <p>Is it possible to make the data destroyed itself if the lastModifiedTime showed 24 hours ago?</p>
