Hello, our use cases for real-time analytics were quite limited so far. One real time measurement we often require is quality of service on the road and since this is a very localized thing it does not require a lot of processing. Possibly, there are use-cases in analyzing vehicle-to-vehicle communication networks. Maybe someone else on this list has a suggestion. regards, Jakob
