Re: [rules-users] Slow compilation (4h) for a single rule

Thanks for your explanation Edson, it makes sense now I think! Basically what you are saying is that there is a limit, beyond which is no longer feasible to use more ORs on a rule. Edson Tirelli-4 wrote You are trying to avoid the issue. As reported by others, your conditions should be

Re: [rules-users] Slow compilation (4h) for a single rule

Thank you all for your feedback, I will try to implement at least the part of collapsing the multiple evals() into a single one. Edson Tirelli-4 wrote Also, I just read the example in your link where you have multiple accumulates in a single rule... that is *bad* The accumulate()

[rules-users] Slow compilation (4h) for a single rule

Hi, Recently I was trying to optimize the rule compilation time for my KB (~4K rules). I do a full KB compilation every night, as most of the rules are dynamic generated/converted and managed by the business operators. The compile time was not very good (around 3 hours on a 8 core Xeon CPU), but

laune wrote Well, I do mind the nonsense Number(). There's no point in discussing this if you don't post an exact image of your rule. -W There is a point, because the rule I've posted compiles and causes the same problem, I've just removed redundant code to expose the problematic

Re: [rules-users] Slow compilation (4h) for a single rule

I understand that the rule looks pointless and under-optimized, but it's the only way I could represent this kind of rule in an automated way (I didn't write the rule by hand). Basically with these rules I try to pre-compute the amount of some products on the WM (using count() inside a accumulate

Re: [rules-users] drools arithmetics without eval()

Hi, These rules are all auto-generated every day, and I don't control what is going into them, so this kind of optimizations won't work for me. The basic problem here, is that I have tons of rules that count facts (PortfolioProducts) and use the result as rule conditions. Some conditions could

[rules-users] drools arithmetics without eval()

I have a question regarding eval() use. My rulebase is around ~3k rules, most of them are auto-generated by templates, and they end up looking like this: rule CONFIG_114 salience 0 when client: Client() contextProd: PortfolioProduct(prodAdded == true, productId == PROFESSIONAL)

Re: [rules-users] Drools Execution Server memory leak?

Hi, We are having the same problem with a similar setup (drools 5.2.0 Final) using stateless sessions and camel integration, using a KB with ~3000 rules. Session memory is never reclaimed, and after some hours we got an out of memory error. We still dont know the cause, but the profiler shows
