Last weekend at the AT&T Mobile Hackathon I had a pleasure of checking out the MongoLab's MongoDB service. In short: it was a delight to work with. I fell in love with that technology. It worked exactly the way I thought--MongoDB architects got it right. After spending a good part of the day fighting my hibernate configuration in JUnit I was pleasantly surprised when I saw that Mongo keeps their documentation and design accessible with plan old object and simple REST calls to its MongoLab API.
