scroller && ajax.reload() with 50000 records sometimes show blank table

Hello all,

I'm trying to render 50,000 data in datatable with scroller and automatically update
However, sometimes it just show blank table after ajax.reload()

Came from here
https://datatables.net/forums/discussion/36000/how-to-store-scroller-position-when-use-ajax-reload

This is a re-producible demo, reproduce step:
1. drag the scroller bar to a big number, e.g. 10000
2. keep scrolling down using wheel
3. sometimes after ajax.reload, it will show blank table like this

Any help would be appreciate (including any technique that I can render 50000 data and auto-updated without pagination)

    Hi @yuhan ,

    There's an outstanding issue in the backlog, see here, which sounds similar. There is a workaround in that thread, please could you sere if that works for you,

    Hey, Colin.

    Nice to see you!

    I believe there is an issue with ajax.reload
    As you can see, if I drag the Y scroll bar to huge number, the row number keeps jumping to around half for each polling (while the scroll bar position stick)

    This is the new demo

    I tried several things yesterday and felt the ajax.reload seems to be the issue. I worked around this by giving up ajax.reload and using table.clear().rows.add(), this is my solution.

    Yeah, quite similar as the thread.

    But I do feel scroller has something wrong with ajax.reload

    Cheers!
