Hi, I'm using Drools 5.1. I set one agenda-goup with an auto-focus set on rule of the greatest salience. I'm using multithreading to launch multiple sessions in parallel. Problem is that I'm not getting same results whether I put 1 or multiple facts in sessions. It is as if rules weren't evaluated for facts in case multiple facts were inserted in sessions. I suppose I'm not understanding well usage of agenda-group. What I would like to to do is to : - first evaluate set of rules for inserted facts, - once all previous facts were updated by first set of rules, evaluate default set of rules for other facts and previous updated facts. Is agenda-group adapted for such a result ? How can I explain differences found depending of number of facts inserted in sessions working in parallel ?
