title: Should time partition column be set as clustered column in BigQuery?
body: <p>I am wondering that if there is any benefit or impact if the date partition column is set as the first clustered column?</p>
  
  <p>I can not find any document to specify that.</p>
  
  <p>I would assume that's not needed but in my test, it can be done. So what would happen if the date partition column is set as the first clustered column?</p>
