[rules-users] Speed up inserting of rules into knowledge base

[Piotr Jedrychowski]

Hello.

I'm loading a big amount of rules during starting of JBoss (20000 
rules). All rules (in string format) are available before JBoss startup 
- they are stored into database. Rules are loaded one by one and it 
takes about 90 minutes. I want to speed up this process. Is there 
something like "bulk load" for inserting rules into knowledge base or 
another smart way to fast loading a big amount of rules?

I'm using:
1) Drools 5.1
2) JBoss 4.2.3

My source code looks like this:

String rule = ...
Resource resource = ResourceFactory.newReaderResource(new 
StringReader(rule));
KnowledgeBuilder knowledgeBuilder = 
KnowledgeBuilderFactory.newKnowledgeBuilder();
knowledgeBuilder.add(resource, ResourceType.DRL);
knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());

Regards,
Piotr
