title: Drools :- multiple(thousands) .drl files , each having multiple rules , execution of each file should be controlled as required
body: <p>I'm new to drools rule engine. In my project, I have multiple <code>.drl</code> files of drools to run. But <code>readknowledgebase()</code> takes time to run rules. So, I want to learn the best way of loading all rule files (multiple <code>.drl</code> files) once, and then run the rules of each <code>.drl</code> file one after another as required, instead of running all rules of all <code>.drl</code> files each time I make a call to <code>knowledgebase()</code>.</p>
