Hi, I am using drools for 2 of our projects. For one of them I have more than 20K simple rules. But with number of rules I have started seeing out of memory exceptions and also configuring 20K rules through guvnor is difficult. Is there an alternative for this? Is there something like file upload for drl on guvnor ? Is there a limit on number of rules ?

As an aside to Wolfgang's comments, it is possible to import DRL into Guvnor.

I am not sure I understand that. What is the other option for this case. Why would simple rules not work for 20 K rules. Am I missing something. I cannot use database to store my rules. Drools also gives me salience which I need for my usecase.

My rules are as follows. rule "rule1" salience -2 dialect "mvel" when stud : Student ( field == "ARTS", state.equals("WA")) then java.util.List subList = new java.util.ArrayList(); Subject subject = new Subject(); subject.setName("ABC"); subject.setFees(33454); subject.duration(4); subList.add(subject); subject = new Subject(); subject.setName("XYZ"); subject.setFees(33454); subject.duration(4); subList.add(subject); stud.setSubjects(subList); end rule "rule2" salience -100 dialect "mvel" when stud : Student ( field == "ARTS", state.equals("WA") , city == "SEATTLE")) then java.util.List subList = new java.util.ArrayList(); Subject subject = new Subject(); subject.setName("ABC"); subject.setFees(33454); subject.duration(4); subList.add(subject); subject = new Subject(); subject.setName("XYZ"); subject.setFees(33454); subject.duration(4); subList.add(subject); stud.setSubjects(subList); end Student is the main object and it contains List of Subjects. here the way I am using the salience because if the input us shweta, ARTS, WA,Olympia it matched rule1 but if the input is shweta, ARTS, WA, Seattle it matches 1 and 2 but i want the rule 2 to be executed so salience. I am using StatelessKnowledge Session and also the resource change scanner. I execute one rule at a time and the scanner poll interval is 1 hour. When I started with 100 rules I was using "PK" as my source in changeSet.xml but when the rules grew to 20K I was not able to build the rules in Guvnor UI and hence I started using "DRL" as source. The way I generate drl is using a script which converts the csv to drl format. I copy the drl to the text area in techincal rules and save it. ( this copy is also paiful so I asked that if there is an upload drl file unlike the import drl file) In changeset I give the path to the url in webdav /guvnor/org.drools.guvnor.Guvnor/webdav/packages/StudentRules/StudentRules.drl I am not sure if I am doing it the right way. Please suggest.

I can look into the solution of writing my own Java application for this solution. But I would still like to understand, if the problem is just because of the 3 values being checked in the rules ? Do complex rules dont have more than 1 checks ? If yes then this case should be supported no matter how simple the rule is right ? Also for the UI issue I mentioned. Assume some other complex rules. Is copying the thousands of lines in the text area not a problem in guvnor ?

Hello, I just worked on a drools project with many thousands rules (100k). The project is now in production. the issues are : 1) Guvnor needs more that 2.5GB Ram => Go to 64 bits java (we have 5GB heap) 2) Building the binary on guvnor on a virtual environment takes a few minutes (4 minutes in our case) 3) For the runtime, the rulebase to build is less then 1 minute when getting the rulebase from guvnor 4) We are using decision tables updated from remote, so to view them the only way is to download via rest the decision table xml et edit it. 5) Performance are excellent, for one session execution, it takes 250 ms to apply 300 rules again in a virtual environement. I would like to know which JIRA is related to the issues in guvnor when there are many lines ?
