title: Is it possible to query JSON data in DynamoDB?
body: <p>Let's say my JSON looks like this (example provided <a href="http://docs.aws.amazon.com/amazondynamodb/latest/gettingstartedguide/GettingStarted.Java.02.html" rel="noreferrer">here</a>) -</p>
  
  <pre><code>{
      "year" : 2013,
      "title" : "Turn It Down, Or Else!",
      "info" : {
          "directors" : [
              "Alice Smith",
              "Bob Jones"
          ],

  <p>I would like to query all movies where <code>genres</code> contains <code>Drama</code>.</p>
  
  <p>I went through all of the examples but it seems that I can query only on hash key and sort key. I can't have JSON document as key itself as that is not supported. </p>
