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

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
