A scalable complex event processing system and evaluations of its performance

Scalable Complex Event Processing Using Rule Distribution

“…The results of evaluation of ARD is compared with two other static load-balancing techniques. The first is SCTXPF [8] that balances the number of rules on CEP nodes. The second is VISIRI [9] that uses a rule cost estimation to distribute rules among CEP nodes according to the estimated costs.…”

“…In this category of horizontal scaling of CEP, users can use popular CEP engines and their familiar rule syntaxes. Some of the previously proposed techniques for CEP clustering such as those reported in [8], [9], [18], [19] only balance the load of the system statically via distributing the rules among the compute nodes. Therefore they do not handle changes in the system workload pattern during the lifetime of the system.…”

VISIRI - Distributed Complex Event Processing System for Handling Large Number of Queries

“…Traditional CEP systems with central processing engines have failed to cater to the requirement of processing large number of events generated from a large number of geographically distributed sources [2,4]. Distributed CEP systems have been identified as the best alternative for this.…”

“…Crucial decisions have to be taken on how to distribute the load among the complex event processing nodes in the system. There are two approaches in distributing the processing load among nodes : operator distribution and query distribution [1,4]. Operator distribution refers to the approach of dividing a query into a distinct sequence of steps to handle complex queries.…”

“…For example, the COSMOS project [8] focused on reducing network latency and reducing communication between the nodes. The SCTXPF system [4] focused only on reducing the event duplication network traffic within the system.…”
