title: AWS Glue Job Bookmarking
body: <p>Wanted to see if there are more details about the way job bookmarking is done in AWS Glue. AWS docs doesn't provide much on this. I know that there are basic functionality in there:</p>
  
  <ul>
  <li>enable</li>
  <li>disable</li>
  <li>pause </li>
  <li>reset</li>
  </ul>
  
  <p>And it seems like that the bookmarking happens at the time: </p>
  
  <pre><code>job.commit()
  </code></pre>
  
  <p>Can I access it? Can it be modified to reprocess some portion of source?</p>
