[rules-users] Time Taken To Load Rule Resource

[Adeyinka Timi]

Hi,

 

Thanks for the help!

 

I have tried implemented your idea by creating a method that compiles the
rules resources (DRL and RF files). But I keep getting a 

 

java.lang.RuntimeException: java.io.EOFException 

 

error when I call
kbuilder.add(ResourceFactory.newFileResource("/some/file.pkg"),
ResourceType.PKG); 

 

Any ideas?

Yes, you can compile your rules once and save them as binary files. Here is
a code snippet to do that:

 

                KnowledgePackage pkg = (KnowledgePackage) kbuilder
.getKnowledgePackages().iterator().next();

                FileOutputStream out = new
FileOutputStream("/some/file.pkg");

                        try {

                                    DroolsStreamUtils.streamOut(out, pkg);

                        } finally {

                                    out.close();

                        }

 

The code above only uses kbuilder's first package.

The way you load a binary package is the same as you do for DRL files:

 

 
kbuilder.add(ResourceFactory.newFileResource("/some/file.pkg",
ResourceType.PKG); 

 

Hope you find this useful!

Thanks for your reply!

No particular reason. Is there a better of going about this - avoid
compilation of rules everytime?

Is there any reason why you need to compile the rules every time your app
starts?

Hi guys,

 

I have a drools application running that takes about 7 seconds to run. 5
seconds of this time is used in parsing 2 DRL files that 200kb (6200 lines
of code) and 34kb (1400 lines of code). Do you guys have any tips or any
techniques that I can use to improve performance?
