How to write Drool rules for huge data Excel sheet?

Question

While trying to load huge data(around 1,00,000 records) throws "GC overhead limit exceeded" error. The code snippet used is below:

public static void GridUploadPVT() throws Exception {
    try {
        KnowledgeBase knowledgeBaseTest = genKnowledgeBaseXlsx("GridUploadPVT.xlsx");
        StatelessKnowledgeSession session = knowledgeBaseTest.newStatelessKnowledgeSession();

        GridUploadPVT griduploadpvt = new GridUploadPVT(prodName, xAxis, yAxis, tranType, vehAge, "YES");
        session.execute(griduploadpvt);

    } catch (Exception ex) {
        System.out.println("Exception:" + ex.toString());
        throw new RuntimeException(excommonItem);
    }
}

private static KnowledgeBase genKnowledgeBaseXlsx(String xlsx) throws Exception {
    DecisionTableConfiguration dtconf = KnowledgeBuilderFactory.newDecisionTableConfiguration();
    dtconf.setInputType(DecisionTableInputType.XLSX);

    KnowledgeBuilder knowledgeBuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
    knowledgeBuilder.add(ResourceFactory.newClassPathResource(xlsx),
            ResourceType.DTABLE, dtconf);

    if (knowledgeBuilder.hasErrors()) {
        throw new RuntimeException(knowledgeBuilder.getErrors().toString());
    }

    KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();
    knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());
    return knowledgeBase;
}
