Using a Report Cache Mode
Наши примеры проектов и шаблоны отчётов помогут Вам разобраться в основах работы с нашими продуктами.For very large reports, cache mode keeps memory usage low by holding only part of the rendered document in memory at a time.
Cache lifecycle. Choose a stable cache key, store the report between requests, and restore it before the next viewer or designer action.

var Stimulsoft = require('stimulsoft-reports-js');
var report = new Stimulsoft.Report.StiReport();
report.loadFile("Over-2.000-pages.mrt");
report.reportCacheMode = Stimulsoft.Report.StiReportCacheMode.On;
Stimulsoft.StiOptions.Engine.ReportCache.amountOfQuickAccessPages = 50; // default 50
report.renderAsync(() => {
console.log("Pages: ", report.renderedPages.count);
report.saveDocumentFile("Over-2.000-pages.mdc");
report.dispose();
});reportCacheMode = On streams rendered pages to a cache instead of keeping them all in memory; amountOfQuickAccessPages controls how many stay readily available. Calling dispose() afterwards frees the resources — important for long-running Node.js services.
