title: How to add a new field on a DynamoDB table?
body: <p>I am a total beginner on <code>DynamoDB</code> and hardly know how to make a working query. But I recently came up with something which is apparently doing what I want.</p>
  
  <p>Here is my question, I now have a table like this:</p>
  
  <p>It has a primary partition key and a primary sort key:</p>
  
  <pre><code>Primary partition key
      primaryPartitionIdKey (String)
  Primary sort key
      primarySortIdKey (String)
  </code></pre>
  
  <p>But two fields are not enough to do what I need. I would like to add one more.</p>
  
  <pre><code>Another field:
      otherFieldIdKey (String)
  </code></pre>
  
  <p>Is that possible, if YES: how should I do it?</p>
  
  <p>I can' see anything on the AWS console for that.</p>
