Hi Humberto,

I guess Fuji is familiar with Flink CEP and he can answer your proposed 
question. I already cc him.

Best,
Zhijiang

Subject:FlinkCEP - Detect absence of a certain event

In the documentation of FlinkCEP, I found that I can enforce that a particular 
event doesn't occur between two other events using notFollowedBy or notNext.
However, I was wondering If I could detect the absence of a certain event after 
a time X. For example, if an event A is not followed by another event A within 
10 seconds, fire an alert or do something.
Could be possible to define a FlinkCEP pattern to capture that situation?
Thanks in advance, Humberto
