Re: [rules-users] Java Heap Space Out of Memory in Drools
The rule starts by pairing each Employee with each Requirement and so you have 1000*1000 = 100 nodes in the network. This is an anti-pattern for counting pairs from a subset (1%) of all pairs. To count Assignments with identical pairs of Employee and Requirements you just look at Assignments. Ideally, Assignments has an attribute that enumerates them (or some other unique comparable id - a simple object counter will do). Then you start the rule with Assignment( $e: employee, $r: requirement, $id: id) not Assignment( employee == $e, requirement == $r, id $id ) ...accumulate...

The number of assignment therefore would be number of months of requirment * number of requirement all in all 1 assignments. -- View this message in context: http://drools.46999.n3.nabble.com/Java-Heap-Space-Out-of-Memory-tp4026825p4026839.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Would that be the cause of this problem? By default, OptaPlanner uses selectors with cacheType=JIT, which can handle 50K entities with 5k values. If you specifically specify cacheType=STEP|PHASE or use a custom MoveListFactory, look into using JIT or MoveIteratorFactory instead. If that's not the case, what score calculation are you using? What's the stacktrace? Use a tool like VisualVM to find out what is causing the problem.
