What exactly is Uber running in its clusters?

- Route Optimization

- Demand Forecasting

- Rider Hotspot Prediction

This post doesn't exactly tell us the true nature of their workloads (other than the crude categorization - batch, stateful, stateless), nor does it talk about the inflection points where off-the-shelf solutions don't cut it anymore and such customization is required. I mean some before & after numbers / graphs on resource utilization would have really helped.
