Abstract

The invention provides a complex event matching method and device based on an ordered event list and a storage medium. The method comprises the steps that a query mode and a given event stream are preset; wherein the query mode comprises a target sequence, an attribute constraint condition, an event window size and an output expression form; performing preliminary filtering on event instances in an event stream by utilizing the query mode, and caching event types conforming to the query mode and event instances meeting attribute constraint conditions to obtain a corresponding ordered event list buffer area; executing a matching operation meeting the query mode on the ordered event list buffer area to obtain a candidate sequence result of the complex event; and verifying the complex event candidate sequence to obtain and output a complex event result so as to solve the problems of complex processing mode, easy generation of a large number of intermediate results and low processing efficiency of a computer in the aspect of complex event processing.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular to a complex event matching method, device and storage medium based on an ordered event list. Background technique [0002] With the rapid development of information technology, the data generated by various information systems has grown exponentially, and large-scale data analysis and processing have been widely used in various industries. The current complex event processing methods can be roughly divided into three categories: based on automata model, based on logic model and based on tree model. However, these methods have certain limitations, the processing methods are complicated, a large number of intermediate results are likely to be generated, and the processing efficiency is low. Contents of the invention [0003] The present application provides a complex event matching method based on an ordered event list and a device storage medium to so...
