title: MongoDB write concern for strong consistent
body: <p>I have Java processes to update MongoDB 3.6.0. I have 1 - primary, 2 replicas. The flow is</p>
  <ol>
  <li><p>Update some data in a document having a specific &quot;_id&quot;</p>
  </li>
  <li><p>Read from replicas</p>
  </li>
  </ol>
  <p>Sometimes, read gets an older version of the document.We decided to use WriteConcern to address this -</p>
  <pre><code>WriteConcern(WriteConcern.W3.withWTimeout(100, TimeUnit.MILLISECONDS).withJournal(false));
  </code></pre>
  <p>With the introduction of WriteConcern there will be some latency and to avoid too much latencies i skipped updating the Journal log</p>
  <p>Is the above config going to work ?</p>
