Let's say I have 10 rules and I fire the same object over it multiple times. This means the result that I would get back is the same every time, since it is the same object over the same rules (In a stateless environment). Does Drools cache the result internally for such cases? Knowing that when the same object comes over the same rules it can give the result back right away instead of going over the rules first. Just something I want to know and couldn't really find in the documentation easily. -- View this message in context: http://drools.46999.n3.nabble.com/Identical-Facts-over-rules-results-bein...

Wouldn't that depend on how long the data is being kept and how often identical rules are being fired? Or would you say the rule engine is faster than all the actions in between that it wouldnt matter? -- View this message in context: http://drools.46999.n3.nabble.com/Identical-Facts-over-rules-results-bein...

If it's general enough, it is not something to be shrugged off as "not that hard". You'll have to keep the fact and memorize all rules it fires, and create a mechanism that'll let you call right hand sides when the duplicate fact arrives and with all variables bound to the same values.
