title: Batch insert using jdbcTemplate.batchUpdate confusion
body: <p>Does <code>jdbcTemplate.batchUpdate</code> execute multiple single insert statements <strong>OR</strong> 1 multi value list insert on the database server?</p>
  
  <p>I know that it sends the complete query payload at once to the server but am not sure how the execution takes place.</p>
  
  <p>Can someone please explain/help?</p>
