[rules-users] Event consuming policy

Hi Guys, I was working lately with drools fusion, we wanted to know what event consumption policy was implemented. We made the following simple rule : rule a when $c1 : Event(symbol == 1 , $l1 :load) from entry-point "mainS" and $c2 : Event(this after $c1,symbol == 2,$l2 :load) from entry-point "mainS" then System.out.println("event1 "+$l1+" event2 "+$l2); end The event class has just symbol : int and load : int , load is used to differentiate between different events that have the same symbol. and then we declared the following events into the stream using the constructor Event(symbol,load): with mainS being a WorkingMemoryEntrypoint mainS.insert(new Event(1,10.0)); mainS.insert((new Event(1,20.0))); mainS.insert((new Event(1,30.0))); mainS.insert(new Event(2,80.0)); mainS.insert(new Event(2,90.0)); We have the following output : event1 30.0 event2 90.0 event1 20.0 event2 90.0 event1 10.0 event2 90.0 event1 10.0 event2 80.0 So what is exactly the consumption policy used in DROOLS ? It seems that is unrestricted for event 90.0 and chronological for event 80 . We have tested different situations and order of events and we always came to the conclusion that for the first $c2 the policy is chronological and for all the other $c2's it is unrestricted. Thank you for you time. Khalil
