我试图理解这个Flinkcep的例子
https://github.com/tillrohrmann/cep-monitoring ..我在分布式模式下执行了这个flink cep的例子(1个主机和3个内核)…现在我将输出写入文件,因此我的输出被写入3个文件,因为有3个内核..在其中一个文件中,我看到如下记录:

如果我们从第五行开始看。我们可以检查从第5行打印的所有温度表(即对于温度:113.65291115679136),我们可以在temperaturewarning中识别低于(温度:113.65291115679136出现在第15行)的温度,即我们可以识别哪些温度,警报已经打印出来了…但是从第1行到第4行生成的警报呢??你甚至可以在第11行找到同样的记录。。我的意思是,我们如何才能确定已经生成警报的温度警告??它是以批处理模式、连续模式还是微批处理模式执行流处理??

当在10秒内从同一机架id出现两个连续的温度事件时,会生成温度警告。
当同一机架id的20秒内连续出现两次温度警告且温度警告温度似乎在升高时,会生成温度警报。温度警报有第一次温度警告的数据
它是连续流源
