RACE: Real-time Applications over Cloud-Edge

The Cloud-Edge topology – where multiple smart edge devices such as phones are connected to one another via the Cloud – is becoming ubiquitous. We demonstrate RACE, a new framework and system for specifying and efficiently executing distributed real-time applications in the Cloud-Edge topology. RACE uses LINQ for StreamInsight to succinctly express a diverse suite of useful real-time applications. Further, it exploits the processing power of edge devices and the Cloud to partition and execute such queries in a distributed manner. RACE features a novel cost-based optimizer that efficiently finds the optimal placement, minimizing global communication cost while handling multi-level join queries and asymmetric network links.
