Hi Can anyone tell me how to Implement temporal based event correlation using drools fusion in a load balancing environment. What is the best practice in a situation like this?? Use case : To correlate events which comes into the system with in a time window. Scenario1: Single System Scenario: that is One working memory 1.All the events come into the system, 2.Temporal based rules are written using Drools-Fusion. 3.Correlations takes place if all the events come with in the time window, else the rule expires. Note: All these takes place with in a single working memory ( Single System) Scenario2: Two System Scenario in active/active: that is two working memories 1.All the events come into the system, 2.Temporal based rules are written using Drools-Fusion. 3. Same rules are deployed in both the systems (active/active) 4.Both systems are load-balanced, 5. Event1 goes to System1, Event2 goes to System2 and again Event3 goes system1. ( load -balanced) As a result, System1 recieves 2 events out of 3 events, and System2 the other 1 event. Correlation never happens since I dont recieve all the events in a single working memory. How do we handle this kinda scenario?? Do we have any best practise that is followed in a clustered or load-balanced environment?? Pls help me.. I am stuck. Regds Chetan In a single system, Fusion/temporal based correlation works completely fine. Use case: I have a situation, where events flow into two active components (both running simultaneosly) _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
