title: Recommendation Engines Test data
body: <p>I've started learning of recommendation systems theory and I want to start practice. But unfortunately, I've faced with next problem : I want test my code on some big data set (size around 100 MB - 1 GB) and I didn't find any open sources for such data. Also, I found few test data generators, but I want find some example of "real life data", instead of purely artificial data.</p>
  
  <p>Where can I find such data sets?</p>
  
  <p>Thanks in advance! </p>
