  node.js, question

Paging is carried out according to the data (total) returned by a server side. Paging instructions can be reloaded when total is changed.

Total changes indicate that the length of the data has changed. If there is no problem with your instructions, the instructions will reload the page due to the data changes. If you have a lot of data, there may be a big hole in performance.
