support for UICollectionView with paging

[ballard]

Is your feature request related to a problem? Please describe.
I'm trying to implement UICollectionView with diffable data source like DifferenceKit (https://github.com/ra1028/DifferenceKit). It is suggested to use such framework with paginated data source, because when we have 20-30k elements in our database we have perfomance issues when data source is changed.

Say if we have some photos backup storage with 30k items and we downloading list of the images into our app with chunks of data by 500 items, and save them to CoreData or Realm and we should display them like in google photos app. So if we already have 10k items and we periodically adding items our app freezes.

Describe the solution you'd like

So target is to display say 1000 items and load from core data when user scrolling down
But we need FastScroll to work across ALL (maybe 20-30k) stored items

Is it possible?

Did you ever resolve this? We also have to page the results in and this solution doesn't work for us.
