Hello Alfred, Just some considerations from my side as for the latency. I think the first step should be defining what does "latency" for a CEP library really means. The first thing that comes to my mind is the time period between the arrival of an event that should trigger a match (ending pattern) and actual time when the match is emitted(for that case a select function is a good place I think).
I think Kostas was also referring to similar kind of issue. Hope it will be helpful. Z pozdrowieniami! / Cheers!
