Re: [rules-users] Drools STREAM Mode performance with rather simple rule
Hello again! Thanks for the heads up, Wolfgang. Basically, what I try to create is some sort of batch window, which is not really implemented into Drools Fusion if I remember correctly. It doesn't HAVE to be A, B, C in that particular order which I specified in my last post, but the rule shall only match each A, each B, and each C once. So what would you recommend as a best practise to build that rule? Or is my rule correct? Actually, I don't like the fact, that I have to complete the rule by retracting my events in the RHS of the rule. I'd rather have a batch window specified in the LHS. Thanks in advance.

Re: [rules-users] Drools STREAM Mode performance with rather simple rule
Hello again. Thanks for your test Wolfgang. When I do it like you did, I get approx. the same results. But you misunderstood my scenario. I don't want to send ABC x times. Here's what I meant in pseudocode. for ( i = 0; i < X; i++) Send Y times A Send Y times B Send Y times C I dropped the idea of calling fireUntilHalt() and now I call fireAllRules after every single insert, just to be quick. This avoids the problem of getting random execution durations. Now I produce nearly constant times every time I execute this. But it is still not very satisfying. These are just a few hundred events. In a real business scenario it will be a lot more. Increasing X will cause the time to go up linearly which is ok, but increasing Y will have the time go up overproportional, which is not acceptable. We will evaluate this now with a really good machine. But it would be interesting to see what results others achieve in this scenario.

[rules-users] Drools STREAM Mode performance with rather simple rule
Hello everyone. I've got a question regarding the performance of Drools in STREAM mode. It seems to me, that either Drools is not very fast here, or the problem is with the rule itself. This is the rule. rule "ABC" no-loop when $a : Aevent() $b : Bevent(id == $a.id) $c : Cevent(id == $a.id) then retract($c); retract($a); retract($b); ...(actions) end It basically says: act upon every group of A, B and C events with the same ids. The retract statements will make sure, none of these events will get matched again by this rule. Side question: is there any possibility to do this rule without the retractions? Regarding the performance: If I put the arriving events in this sequence: A(x), B(x), C(x) where x is the number of events being sent. No other events than A, B and C with the same id being sent. And I repeat this sequence a small number of runs (12 times in a row), then it will take Drools: For x=8, on average 3 seconds to detect all 96 patterns, for x=16, on average 30 seconds to detect all 192 patterns. But the average is not very meaningful. Sometimes the Engine does it in (x=16) 10 seconds, and sometimes it takes him over a minute to detect everything, sometimes it takes him nearly forever for no reason. We tested this on different machines and we cannot predict a "stable" behaviour. We figured out, that this instability might come from fireUntilHalt, which we invoke from a separate thread. Some ABC groups get detected faster than others and the total duration is totally variable as stated before. When calling fireAllRules upon every insert, the total duration is stable (4,5 sec for x=16 and 12 runs) and also the detection time for every ABC group seems to be even. So a few questions: whats the problem with fireUntilHalt? Are we using it the wrong way? If fireAllRules is used after every insert, can rules be triggered by actions of other rules? For event stream processing a solution that fires almost always is desirable. Why is the overall performance so poor? If I do x=32 and do just one run, which means just a total of 32*3= 96 events being sent and it takes him 2,6 seconds to detect all 32 patterns. That's not very fast, is it? I'm using Drools 5.1.1 and the latest JDK. It would be nice to get some opinions.
