MongoDB or CouchDB - fit for production? [closed]
I'm the CTO of 10gen (developers of MongoDB) so I'm a bit biased, but I also manage a few sites that are using MongoDB in production.
businessinsider has been using mongo in production for over a year now. They are using it for everything from users and blog posts, to every image on the site.
shopwiki is using it for a few things including real time analytics and a caching layer. They are doing over 1000 writes per second to a fairly large database.
If you go to the mongodb Production Deployments page you'll see some people who are using mongo in production.
If you have any questions about the scale or scope of production deployments, post on our user list and we'll be more than happy to help.
