Entire row cache invalidation handles this. - -2. **Memory Tradeoff:** For 1M rows with 10 formatters, expect 50-100MB depending on formatter output size. Users can disable if memory-constrained. - -3. **Timing:** Users rarely export immediately after loading grid, so 30-60 second background population is acceptable. - -4. **Responsiveness:** With `requestAnimationFrame` batching, UI never blocks. Animations/interactions smooth. - -5. **Hidden Columns:** Currently caches all formatter columns (including hidden). Future optimization could skip hidden columns. - ---- - -## References - -- [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) -- [SlickGrid Events](../../packages/common/src/interfaces/slickEvent.interface.ts) -- [ExcelExportService](../../packages/excel-export/src/excelExport.service.ts) -- [Formatter Pattern](../../docs/column-functionalities/formatters.md) - ---- - -## Sign-Off - -**Architecture Review:** ✅ Approved -**Complexity:** Moderate (careful invalidation logic required) -**Risk Level:** Low (backward compatible, opt-in feature) -**Testability:** High (cache is mockable for tests) -**Performance Impact:** Positive (10-18x speedup for large exports) - diff --git a/frameworks/angular-slickgrid/src/library/components/__tests__/angular-slickgrid.component.spec.ts b/frameworks/angular-slickgrid/src/library/components/__tests__/angular-slickgrid.component.spec.ts index fd27d37581..302776f4dd 100644 --- a/frameworks/angular-slickgrid/src/library/components/__tests__/angular-slickgrid.component.spec.ts +++ b/frameworks/angular-slickgrid/src/library/components/__tests__/angular-slickgrid.component.spec.ts @@ -258,6 +258,7 @@ const mockDataView = { onRowCountChanged: new MockSlickEvent(), onSetItemsCalled: new MockSlickEvent(), reSort: vi.fn(), + setGrid: vi.fn(), setItems: vi.fn(), setSelectedIds: vi.fn(), syncGridSelection: vi.fn(), diff --git a/frameworks/angular-slickgrid/src/library/components/angular-slickgrid.component.ts b/frameworks/angular-slickgrid/src/library/components/angular-slickgrid.component.ts index b618fa41e2..b85af6bc8a 100644 --- a/frameworks/angular-slickgrid/src/library/components/angular-slickgrid.component.ts +++ b/frameworks/angular-slickgrid/src/library/components/angular-slickgrid.component.ts @@ -746,6 +746,7 @@ export class AngularSlickgridComponent implements AfterViewInit, On this.options, this._eventPubSubService );

However parsing a large dataset can be slow **and** to make it worst, a Sort will revisit the same items over and over which mean that the same date strings will have to be reparsed over and over (for example while trying to Sort a dataset of 100 items, I saw some items being revisit 10 times and I can only imagine that it is exponentially worst with a large dataset). So what can we do to make this faster with a more reasonable time? Well, we can simply pre-parse all date strings once and only once and convert them to JS Date objects. Then once we get Date objects, we'll simply read the UNIX timestamp which is what we need to Sort. The first pre-parse takes a bit of time and will be executed only on the first date column Sort (any sort afterward will read the pre-parsed Date objects). diff --git a/docs/developer-guides/large-dataset-performance.md b/docs/developer-guides/large-dataset-performance.md new file mode 100644 index 0000000000..9a93a5d99c --- /dev/null +++ b/docs/developer-guides/large-dataset-performance.md @@ -0,0 +1,76 @@ +# Large Dataset Performance Guide + +This guide summarizes the main options to keep large dataset grids responsive when sorting and exporting. + +## When To Use What + +- Use `enableFormattedDataCache` when exports rely on formatters (`exportWithFormatter: true`) and the dataset is large. +- Use `preParseDateColumns` when date sorting is slow because date strings are repeatedly parsed. +- Use both when you have large data with formatter-heavy exports and frequent date sorting. + +## Export Performance (Formatted Cache) + +Enable the DataView formatted cache to pre-compute formatter output in background batches. + +```ts +gridOptions = { + enableFormattedDataCache: true, + // max rows processed per batch tick (default: 300) + formattedDataCacheBatchSize: 300, + // frame-time budget per batch in ms (default: 8) + formattedDataCacheFrameBudgetMs: 8, + excelExportOptions: { + exportWithFormatter: true, + }, + // or pdfExportOptions: { exportWithFormatter: true } +}; +``` + +Notes: + +- Cache population runs in the background and keeps the UI responsive. +- Export services sanitize/decode in their own pipeline, once, at export time. +- Completion events include `durationMs` and can be used for telemetry/spinners. + +```ts +gridContainerElm.addEventListener('onafterexporttoexcel', (e: CustomEvent) => { + console.log('Excel export duration (ms):', e.detail?.durationMs); +}); + +gridContainerElm.addEventListener('onafterexporttopdf', (e: CustomEvent) => { + console.log('PDF export duration (ms):', e.detail?.durationMs); +}); +``` + +## Sorting Performance (`preParseDateColumns`) + +Date sorting on large datasets can be expensive when values are date strings that need parsing for every comparison. +Use `preParseDateColumns` to parse once and sort on `Date` values afterward. + +```ts +gridOptions = { + // Option 1: prefix mode (keeps original string fields) + preParseDateColumns: '__', + + // Option 2: overwrite mode (mutates original date fields) + // preParseDateColumns: true, +}; +``` + +Quick guidance: + +- Prefix mode (`'__'`) is safer for compatibility, but uses more memory. +- Overwrite mode (`true`) uses less memory, but changes original field values to `Date`. + +You can also trigger parsing manually when needed: + +```ts +this.sgb.sortService.preParseAllDateItems(); +this.sgb.sortService.preParseSingleDateItem(item); +``` + +## Related Docs + +- [Sorting](../column-functionalities/sorting.md) +- [Export to Excel](../grid-functionalities/export-to-excel.md) +- [Export to PDF](../grid-functionalities/export-to-pdf.md) diff --git a/docs/grid-functionalities/export-to-excel.md b/docs/grid-functionalities/export-to-excel.md index 447cad699a..5f104404ba 100644 --- a/docs/grid-functionalities/export-to-excel.md +++ b/docs/grid-functionalities/export-to-excel.md @@ -9,6 +9,7 @@ - [Provide Custom Header Title](#provide-a-custom-header-title) - [Export from Button Click](#export-from-a-button-click-event) - [Show Loading Process Spinner](#show-loading-process-spinner) +- [Large Dataset Performance](#large-dataset-performance) - [UI Sample](#ui-sample) ### Description @@ -249,6 +250,35 @@ export class MyExample() { } ``` +### Large Dataset Performance +For large datasets and formatter-heavy exports, you can improve responsiveness by enabling the DataView formatted cache. + +For a combined sorting + export strategy, see [Large Dataset Performance Guide](../developer-guides/large-dataset-performance.md). + +```ts +gridOptions = { + enableFormattedDataCache: true, + // max rows processed per batch tick (defaults to 300) + formattedDataCacheBatchSize: 300, + // frame-time budget per batch in ms (defaults to 8) + formattedDataCacheFrameBudgetMs: 8, + excelExportOptions: { + exportWithFormatter: true, + }, +}; +``` + +Notes: +- Keep sanitization and html decoding in the export service pipeline. +- Cache population can run in the background and does not block the UI. +- onAfterExportToExcel now includes durationMs in the event payload, useful for telemetry/spinners. + +```ts +gridContainerElm.addEventListener('onafterexporttoexcel', (e: CustomEvent) => { + console.log('Export done in ms:', e.detail?.durationMs); +}); +``` + ### UI Sample The Export to Excel handles all characters quite well, from Latin, to Unicode and even Unicorn emoji, it all works on all browsers (`Chrome`, `Firefox`, even `IE11`, I don't have access to older versions).
