title: how to set autocommit = 1 in a sqlalchemy.engine.Connection
body: <p>In sqlalchemy, I make the connection:</p>
  
  <pre><code> conn = engine.connect()
  </code></pre>
  
  <p>I found this will set autocommit = 0 in my mysqld log.
  Now I want to set autocommit = 1 because I do not want to query in a transaction.</p>
  
  <p>Is there a way to do this?</p>
