Abstract

Complex event processing technology is usually implemented based on finite state automaton. During the matching process, a large number of overlapping partial matches will be generated by the event stream. The finite state automaton needs to maintain a large number of repeated matching states, which leads to the problem of redundant calculation in the methods based on this technology. In order to improve the matching efficiency of complex event processing, this paper proposed a method of using complex event instance coverage technology to realize complex event processing. By designing a temporary matching chain partition storage structure and matching algorithms based on this structure, it used complex event instance coverage to reduce redundant calculations, so as to improve the matching efficiency. Experiments were performed on simulated and real datasets, and compared with two commonly used complex event processing technologies. The experimental results show that the proposed method can effectively reduce the redundant computation in the matching process while ensuring the correctness of the matching, and improve the overall matching efficiency.
