Request other nodes to add paging parameters using the parameters of the current console, when I request the next page of data, there is a possibility of data loss.

yes, the right way is to get all subscriber data from other node .
the pageNo should be set 1, the pageSize maybe a constant value such as 10000, but it's a little trick.
is there some better idea?

[haoyann]

Take out all the data, it is recommended to add query conditions according to subscriber IP. @KomachiSion @wanghuigithub What do you think.

[KomachiSion]

I think the best way is query local first, if local subscribers is enough to show current page, do not request other page.

If not enough, query one other node and do the check again.

But the way is a little complex, we can do it step by step, can fix problem by complex first.
