Hello, I have a temporal pattern like *A after B* and a stream as *A1,B1,B2,B3,B4,B5,A2,B6* and if I define a pattern simply as $a: Event() $b: Event(this after $a) I'll get matches like (A1,B1),(A1,B2),(A1,B3),(A1,B4),... However I care about first match only and then I want to reset the pattern so the next one would be (A2,B6). Can you please advice how to achieve that? I don't want to do the deduplication by myself and most importantly I could achieve much better performance if I could expire partial matches (I cannot expire event since it might be used by other patterns) Thanks a lot for help. -- View this message in context: http://drools.46999.n3.nabble.com/Rule-Match-deduplication-tp4020717.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
