While not a "tiny amount of data" Uber's problem seems like one of those embarrassingly parallel ones where partitioning by location is trivial, and accuracy of all the data isn't as important as knowing everyone's location right now. I'd guess any relatively popular MMO deals with similar things under much tighter latency constraints.
Data heavy to me means terabytes of data with potentially multiple dimensions, like Google or Facebook.
Not to say that Uber's problem isn't challenging, but I don't expect that the amount of data is necessarily the problem.
