Hi everyone, I'm trying to find a solution to the following situation: - KnowledgeBase with approx. 1000 rules - Approx. 200 users (hence 200 simultaneous sessions) whereas each session might most likely have different values for the working memory facts So let's say we create a KnowledgeBase (with those 1000 rules) and out of this one KnowledgeBase we create for each existing session its own StatefulKnowledgeSession. Now, how expensive (memory-wise) are these StatefulKnowledgeSessions? Is it reasonable to have more than just a few StatefulKnowledgeSessions? Or is there an other, better approach? Thank you very much! -- View this message in context: http://n3.nabble.com/StatefulKnowledgeSessions-tp688305p688305.html Sent from the Drools - User mailing list archive at Nabble.com.
