title: Is Cassandra production ready for Ruby on Rails?
body: <p>I'm working on a project that is considering using Cassandra as a database.  We would like to eventually migrate to Cassandra even if we use MySQL to start with, given its scalability.  I know that big companies like Facebook, Digg, and recently Twitter is using Cassandra, but I don't believe any of those sites run off Rails.  My question is whether or not it's feasible to use Cassandra using Ruby on Rails.  Points to consider:</p>
  
  <ol>
  <li>We heavily rely on the Authlogic gem.  Would switching to Cassandra affect how it works?</li>
  <li>Are there any mature ruby clients for Cassandra?  Looking on Github it seems that <a href="http://github.com/twitter/cassandra" rel="noreferrer">fauna's client (now twitters's client)</a> is the most mature.  Has anyone had production experience with it?</li>
  </ol>
  
  <p>Appreciate any tips.</p>
