（1）简介及应用场景：复杂事件处理(CEP)既是把不同的数据看做不同的事件，并且通过分析事件之间的关系建立起一套事件关系序列库。利用过滤，聚合，关联性，依赖，层次等技术，最终实现由简单关系产生高级事件关系。复杂事件主要应用场景：主要用于信用卡欺诈检测、用户风险检测、设备故障检测、攻击行为分析等领域。Flink CEP能够利用的场景较多，在实际业务场景中也有了广泛的使用案例与经验积累。比如在可编程....

flink cep 如何处理超时事件？

想请教下各位。我有个用户开户超时断点的场景。调研了一下，想通过flink cep 来实现。但是我定义pattern 后发现，我的这个没办法在一条事件数据上完成判定。必须借助和上一事件数据比较之后判断是不是超时。想知道该如何定义pattern 能够，取到排序之后前后两个两个事件。*来自志愿者整理的flink邮件归档
