RFC (Request for comments): Inbox Pagination

[jakerenzella]

Currently, the task inbox tries to load all items to be displayed. For very large courses with a large number of items in the inbox, this causes significant delays and is generally not performant.

As such, we need to implement some sort of pagination - similar to loading emails in Gmail for example.

Looking at Gmail, by default, they load 50 items at a time with buttons to move to the next 50:

Things to discuss and consider:

• What if new items appear and you move to the next 50 items, would they appear at the top of the second page? Or at the top of the first?
• When would you expect the inbox to pull new items?
• Would there be any significant user benefit for a continuously-scrolling pagination?
• What else aren't we considering?
