Complex Event Processing with grule

[dbakti7]

Hello!

We are evaluating rules engine for our use case, one strong candidate is of course Drools because we are interested with its CEP.
But we are also interested in Go-based engine, and grule is one of them.

About CEP, in particular, I cannot find in documentation ways to:

1. Expire a fact so we don't need to retract them manually
2. way to declare sliding window of time

Could you please advise if I'm missing something in docs? or it's indeed not supported by grule?
Thank you!
