An efficient rule balancing for scalable complex event processing

Owing to Big Data popularity, the metrics Variety, Volume and Velocity (V3), are gaining importance in large scale data intensive applications. Complex Event Processing (CEP) is an efficient solution for identifying events of interest on data streams arriving from geographically distributed heterogeneous sources in near-real time. CEP is capable of handling large variety of data with high computational velocity and delivers better solution compared to other existing techniques. However, handling large volume data streams still poses challenge in CEP systems. Hence, a middleware is required to manage huge streams of data on scalable distributed environment. This paper proposes Scalable Complex Event Processing (SCALACEP) framework for managing voluminous data streams. This paper addresses challenges such as state management and efficient rule distribution for design of distributed framework for CEP using the proposed SCALACEP. This paper also proposes a novel way of indexing CEP rules based on Geometric series. The proposed indexing is used for CEP Rule allocation and CEP rule pruning in the SCALACEP system. SCALACEP is evaluated and compared with other existing systems in the constrained virtualized environment and found to give better results in terms of throughput and reduction in Latency and Multicast.
