Re: [rules-users] StatefulKnowledgeSession construction executes sequentially (no multithread)

-----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users- bounces(a)lists.jboss.org] On Behalf Of Juan Carlos Fernández Sent: 11 October 2011 11:49 To: rules-users(a)lists.jboss.org Subject: Re: [rules-users] StatefulKnowledgeSession construction executes sequentially (no multithread) We create one StatefulKnowledgeSession for every client (if 20 clients at same time, 20 StatefulKnowledgeSession are created) because every client has different environment for rule evaluation. Facts for one client does not have to collide with facts of other clients so this is the reason why we create multiple sessions. Let me explain all this in greater detail. When a client executes a SOAP operation, one StatefulKnowledgeSession is created and associated to the transaction. Every log generated by the transaction is inserted as a Fact. When transaction finishes, we fire all rules for the current transaction knowledge session in order to correlate all transaction logs. This transaction logs do not have to collide with other transaction logs so every thread (transaction) has its own StatefulKnowledgeSession. Our app locks and begin to use only one CPU thread because of newStatefulKnowledgeSession(). Do you think entry-points would be the solution? Is there any other solution? One solution is to use StatefulKnowledgeSession pool who creates instances but we have to retract all facts when returning session to pool. Concurrent executions and throughput is a key feature of our SOAP application.
