Hi everyone! I just arrived, and I'm wondering if something like this is possible using CEP (sadly, could not find any similar example in docs): example #1: Pattern: a b c Input: a1 b1 a2 b2 c1 c2 Matches: (a1, b1, c1); (a2, b2, c2) <- I only want these two matches example #2: Pattern: a b c Input: a1 a2 b1 a3 b2 c1 c2 b3 c3 Matches: (a1, b1, c1); (a2, b2, c2); (a3, b3, c3) Numbers added for clarity, in fact, they could potentially be same: a1 = a2 = a3; b1 = b2 = b3; c1 = c2 = c3; In other words, something like 'first in, first out' and each input element should be in only one match.
