How do you determine when a "fact is evaluated"? On 29/08/2012, rvkhakhkhar1 <rvkhakhkhar(a)gmail.com&gt; wrote:

There you are not counting "evaluations of facts" but "executions of a rule". If you have a timer on a rule with timer(5s 5s) it will fire for each and every matching fact or combination of facts, as long as this match continues for this particular fact or fact combination. -W On 29/08/2012, rvkhakhkhar1 <rvkhakhkhar(a)gmail.com&gt; wrote:

A rule with a timer results in an activation which is a combination of a rule and a tuple of matching facts; one rule may have any number of pending activations at any time. An activation of a rule with a timer will become reactivated (after having been fired before) when the timer fires again and the rule condition still holds for the associated tuple of fact. -W

"I expected only new facts to be evaluated as I'm running stateful session" It only works this way if you let your session alive in a separate Thread, using fireUntilHalt(). If you use fireAllRules() (by instance each 5s), then yes, everything will be re-evaluated, just as if it were a new session.

I have thread which continously infuse facts to ksession simultaneoulsy. For example, At 5th sec, I have 500 matching facts, with total 1000 facts Before the next invocation I infuse another 1000 facts. So, at 10th sec, Rule considers whole working memory including previously evaluated facts.
