PnP batching loads large SharePoint test lists much faster
Reviewed by Helen Jones
SPGuides published three PnP PowerShell approaches for creating and loading a SharePoint Online list with more than 5,000 test items. Its recommended method batches additions in groups of 100, matching PnP’s documented approach for splitting large SharePoint REST batches.
Adding test records one at a time creates several server requests per item and makes realistic list testing unnecessarily slow. Small test lists can also hide the filtering, indexing and view problems that appear around SharePoint’s 5,000-item list-view threshold. Batching makes it practical to reproduce those conditions before a real list grows into them. The 5,000 figure is a view-processing threshold rather than a hard storage limit, so a fast data load still needs indexed columns, sensible views and checks for any flows triggered by the imported records.
Analysis
Use a disposable site and a fresh PnP batch to seed a representative list, then test indexed filters and the views users actually open. Disable or isolate connected flows first so the test load does not trigger thousands of unintended runs.
