title: How to load balance SOLR server? Is Redis a good solution?
body: <p>I am writing a web app that will be hitting a SOLR server frequently. I plan to create multiple instances of this SOLR server so that one specific server doesn't get hit too much. What's the best way to load balance this? </p>
  
  <p>I was thinking of creating a Redis store that would store the number of current requests per SOLR server, and querying on this store to get the SOLR server with the least # of current requests. Of course, I would update this store everytime a request is done.</p>
  
  <p>Is this the best approach? What would you do in this situation?</p>
