title: What does "Table does not support optimize, doing recreate + analyze instead" mean?
body: <p>I am working on MySQL 5.5 and trying to do index rebuild using an <code>OPTIMIZE TABLE</code> query. I am getting the error below:</p>
  
  <blockquote>
    <p>Table does not support optimize, doing recreate + analyze instead</p>
  </blockquote>
  
  <p>What does this mean? Is MySQL engine not allowing Index Rebuild? What is being done behind this message, at MySQL 5.5 Engine level?</p>
