Question:
Proton CEP Fiware: delete old received events
Description:
I've got this kind of problem with Proton CEP: i currently have a "Sequence" EPA; its input are 2 events. But these events have different granularity: let's say i have A and B events; i receive N "A" events, and M "B" events, where M << N.
So i'd like to have a rule like "if event of type A is not consumed within X seconds, remove it", otherwise i've got a long A events queue; i only need the rule to be evaluated for closest (temporally) events.
Practically, i've got a fake room temperature sensor that sends its temperature updates every 5seconds, and i've got another program that checks external weather and sends it every minute.
Any idea how to solve this situation?
Thank you very much!
