How Pagination Works

This project uses cursor pagination. Compared to indexed pagination, this method is faster, reduces database load, and decreases response time.

The OFFSET instruction is costly because, in a large database, it requires iterating through many records, increasing response time. This is mitigated by using ORDER BY id > cursor_id.
