Hello All,

I have some queries regarding use of drools as rule engine for my
Application. It would be very helpful if I get some guidance regarding
these:

1) I have an application in which a user logs in, and according to his
profile he is provided with some benefits, and rule engine check for the
eligibility criteria. But if hundreds of thousands of user will log in at
same time, then what will be the performance accordingly. Like, these
concurrent users hitting the server, and so many threads will be generated
and many number of rules will be fired in the session. Will this hamper the
performance of Rule Engine.

2) Suppose I have an application using drools. I create EAR / WAR file of
that application and deploy it on some other system. Would it be still
possible for me to change the rules on the fly. Or some dependencies might
have to be managed.

3) How can we manage sessions in drools? Suppose we are having different
stateful sessions in our application, but time consumption when we
fireAllRules() exceeds the expected time. So is there a mechanism to kill,
restart the session in drools. Could I get some help/document regarding
session Management on drools.


Thanks & Regards,
