Dynamic Reports page reports very large

I have a report developed in Java that uses DynamicReports. When I try to generate a report with more than 1000 pages approximately the system launches a Java Heap Exception. Is there any way to subdivide into smaller reports by Dynamic Reports itself? For example: loading only 100 pages at a time, then 100 more, and so on?

Below is a very generic code that represents a situation where this error occurs.

   public class EncryptedPdfReport {
        public EncryptedPdfReport() {
            build();
        }
        private void build() {
            try {
                JasperPdfExporterBuilder pdfExporter = export.pdfExporter("c:/report.pdf")
                        .setEncrypted(true)
                        .setUserPassword("1234");
                report()
                        .setTemplate(Templates.reportTemplate)
                        .columns(
                                col.column("Item", "item", type.stringType()),
                                col.column("Quantity", "quantity", type.integerType()),
                                col.column("Unit price", "unitprice", type.bigDecimalType()))
                        .title(Templates.createTitleComponent("EncryptedPdfReport"))
                        .pageFooter(Templates.footerComponent)
                        .setDataSource(createDataSource())//exceção acontece //quando esse metodo é chamado
                        .toPdf(pdfExporter);

            } catch (DRException e) {
                e.printStackTrace();
            }

        }

        private JRDataSource createDataSource() {
            DRDataSource dataSource = new DRDataSource("item", "quantity", "unitprice");
//na linha de  baixo estou inserindo uma grande quantidade de dados na //datasource.
            for (int i = 0; i < 2000000000; i++) {
                dataSource.add("Book", (int) (Math.random() * 10) + 1, new BigDecimal(Math.random() * 100 + 1));
            }
            return dataSource;
        }
        public static void main(String[] args) {
            new EncryptedPdfReport();
        }

    }
