Storm Pub-Sub: High Performance, Scalable Content Based Event Matching System Using Storm

Storm pub-sub is a novel high performance publish subscribe system designed to efficiently match events and the subscriptions with high throughput. Moving a content based pub-sub system first to a local cluster and then to a distributed cluster framework is for high performance and scalability. We depart from the use of broker overlays, where each server must support the whole range of operations of a pub-sub service, as well as overlay management and routing functionality. In this system different operations involved in pub-sub are separated to leverage their natural potential for parallelization using bolts. The storm pub-sub is compared with the traditional pub-sub system Siena, a broker based architecture. Through experimentation on local cluster as well as on distributed cluster we show that our approach of designing publish subscribe system on storm scales well for high volume of data. Storm pub-sub system approximately produces 2200 event/s on distributed cluster. In this paper we describe design and implementation of storm pub-sub and evaluate it in terms of scalability and throughput.
