What was Infinity Scroll used for? How many records could be in the table and how was the problem of a large number of records (virtualization) solved?

Infinity Scroll was used for convenient data loading as the page scrolls, so as not to load all records at once and to improve UX.

The table could have tens or hundreds of thousands of records, which would significantly slow down the interface when loaded all at once.

To solve the problem of a large number of records, virtualization was applied — rendering only the visible part of the list in the DOM, and loading and displaying new elements when scrolling, removing invisible ones. This significantly reduced the load on the browser.

Example approach:

• Use a virtualization library, such as react-window or react-virtualized.
• Load data in portions (pagination or lazy loading) when reaching the end of the list.
• Update the component state by adding new elements to the displayed array.

This approach allows smooth and efficient handling of large data volumes without losing performance.
