title: What are the disadvantages of ElasticSearch Doc Values
body: <p>The docs claims:</p>
  <pre><code>10–25% slower than in-memory fielddata
  </code></pre>
  <p>and</p>
  <pre><code>It is possible that doc values will become the default format in the near future
  </code></pre>
  <p>Besides this reduction in speed, what are the downsides of using doc values in all of the properties?</p>
  <p>Thanks!</p>
