When there is a lot of data needed in a view / screen. It takes a lot of performance to load everything all at the same. Sometimes we need to load 50.000 rows or items or lines.
To make sure the performance is okay, we use pagination in our grids. So we only load everything per page.
Use case: our users need to select multiple rows / items over several pages, but when you go to the new page, it loses the selection of the previous page. Which causes inefficiency for them to execute tasks over several pages.
Our proposed solution:
Load on scroll. You still can load chunks of data instead of everything all at the same, but you start loading a new chunk ones you hit a scroll depth. Used frequently in webshops to load products on product listing pages.
