title: Best approch to reindex data every 2 weeks in CloudSearch
body: <p>I'm using cloudSearch to query 200k documents. The Database is updated every 2 weeks, so I need to import these new datas intho CloudSearch.</p>
  
  <p>I want to avoid three things during and after an update :</p>
  
  <ul>
  <li>Impact on CloudSearch domain performances</li>
  <li>Inconsistency on the data during the update (for example if I have a field "city" and I decide to rename "NYC" in "New-York")</li>
  <li>No rollback available </li>
  </ul>
  
  <p>To avoid all of that, I want to create a new domain each time. I will be able to rollback to another domain in case of major failure. I will keep only the 3 last domains (sanitary batch to manage).</p>
  
  <p>Do you have any feedback ? Other advices ?</p>
  
  <p>Thanks,
  Romain.</p>
