Yea I figured. I'm not talking about Facebook at this point, this is a general engineering comment.
My point with the modeling comment is that the might not access it by individual, because models can be trained on statistical averages and time-ordered instead of by individual. Also the models are trained offline (meaning not in real-time).
If you have an analytics table sitting in HDFS ordered by timestamp and you want to produce a realtime UI for users, that'll take some engineering work, right?
