title: Redis: How to increment hash key when adding data?
body: <p>I'm iterating through data and dumping some to a Redis DB.  Here's an example:</p>
  
  <p>hmset id:1 username "bsmith1" department "accounting"</p>
  
  <p>How can I increment the unique ID on the fly and then use that during the next hmset command?  This seems like an obvious ask but I can't quite find the answer.  </p>
