Re: [rules-users] No inferred expiration when correlating events in Drools Fusion

I made up a simple example that detects duplicate messages over a short time window. The rule below seems to work fine, but facts accumulate indefinitely in the working memory. Changing window:length(1) to window:time(10s) does not solve the issue. declare DataEvent @role(event) end rule "Detect duplicates" when DataEvent ( $text: text ) over window:length(1) ArrayList( size >= 2 ) from collect( DataEvent( text == $text ) over window:time( 10s ) ) then System.err.println("Duplicate detected"); end Now, if I change my condition to the following, I see that facts automatically expire and are retracted after 10 seconds. ...when ArrayList( size >= 10 ) from collect( DataEvent( ) over window:time( 10s ) ) then... Many thanks in advance. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
