Abstract: Complex event processing is one of the core technologies in?the big-data age. Since existing several?problems in complex event processing platform, a distributed complex event stream processing platform based on CEStream（a complex event stream processing language） is proposed, providing event detection based on regular twig pattern and complex event processing of multi-sources. According to composite event pattern of multiple sources, the platform can decompose complex event into several?independent?event detection?tasks and deploy them on different nodes of cluster and remote event detection agents. As the experiments show, the throughput and response time of the system comply with the requirements of mainstream of complex event stream processing.

Key words: complex event processing, stream computing, distributed system, regular twig pattern

摘要： 复杂事件处理是大数据时代的关键技术之一。针对现有的复杂事件处理平台存在的各种问题，提出并设计了一个以复杂事件流处理语言CEStream为基础的分布式复杂事件流处理平台，实现了基于正规树模式的事件检测功能，支持多数据源的复杂事件处理。针对多数据源组合事件模式的检测需求，该平台可以将复杂事件分解为多个独立的事件检测任务，部署在集群中不同节点和远端的事件检测代理上。实验结果表明，系统的吞吐量和响应时间达到了预期结果，可以满足目前主流的复杂事件处理的应用需求。
