title: Mongodb/Couchdb instead of MySQL (Switching from PHP to Node)
body: <p>I've done most of my web development using PHP/MySQL/Solr on the backend and Javascript/jQuery/Backbone on the frontend.</p>
  
  <p>I've already written some Node apps, but using MySQL instead of Mongodb/Couchdb which many Node tutorials/books uses. Would you start using Mongo/Couch instead of MySQL because most people developing Node is using it? MySQL seems to work fine for me and I'm unclear of the advantages of switching to Mongo/Couch.</p>
  
  <p>Right now I am starting a site where the "frontend" app server is PHP/MySQL, and the number crunching server is in Node. My reason for sticking to PHP to serve the "frontned" is because I'm extremely comfortable developing in my PHP framework.</p>
  
  <p>Reason for choosing Node is because there will be alot of simultaneous tasks with idle/wait times in the order of seconds. And this has to be highly scalable.</p>
