Pagination for AWS S3 Bucket Objects

[EricPyZhou]

Hello there, here is my question:

Suppose I have 100 objects and on the UI I have a pagination component that shows 10 objects each page.

To be able to jump to any page, currently in backend, I need to fetch all 100 objects and slice the needed range of array and return to UI. However, it results in extra cost of data tranfer and processing.

I thought of few ways, e.g. caching the whole list, but didnt figure out a way to efficiently let my backend be notified by new changes (can not get rid of possibilities of stale reads by just polling the API within some intervals).

Is there a way to just get a given index range of objects? is that possible solely relying on existing APIs?
