Hello, (I'm sorry if this question already has been asked.) My company uses Drools for answering questions. For every asked question, a new StateFulknowledgeSession is created and after the question has been answerd by Drools, the StateFulknowledgeSession is being disposed. Now we have the situation that multiple questions can be asked at the same point of time. That's why we have to decide if we should have only one StatefulKnowledgeSession at a time (i.e execute the questions sequentially) or allow parallelism (i.e. have many instances of StateFulknowledgeSession at one time). Which from the both alternatives would you propose to use? On what could depend our decision? Many thanks and best regards, Svetlomir Kasabov. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Multiple-StatefulKnow...
