Re: [rules-users] Removing many facts have invalid timestamp

From your code it would appear that one time has to occur fivefold or

Trying to figure out if it can be done in a rule almost some sort of pre rule before other rules are triggered. The current rule I have is rule "RemoveInvalidEndTimestamps" salience 100 when $factN : Fact() $factsToRemove : ArrayList(size>=5) from collect( Fact(endTime==$factN.endTime)) then List newFactsToRemove = new ArrayList(); newFactsToRemove.addAll($factsToRemove); for(Fact n : newFactsToRemove ){ retract(n); } end I am using a cloud based process . I could sort the facts and stream them in. Just in a few test cases there are many facts with invalid times , which kills the speed . >From the log I think that each collection of size>=5 , is triggered which means triggered for 5,6,7, etc. Just wondering if there is way to say before doing any other rules collect up all these invalid times and remove them. I was just going to write up a some java code and filter before feeding facts into drools but I find the rule syntax is much easier to read for the non software developers in my group. -- Thanks, Benjamin Bennett <benbennett(a)gmail.com&gt;
