In Day 71, we upgrade our architectural knowledge by exploring Cursor-Based Pagination.
While the Limit/Offset method we built works for small apps, it crashes and burns at scale. Today, we break down the System Design principles behind high-performance feeds.
The "Offset" Problem: Why OFFSET 10000 forces your database to read 10,000 rows just to throw them away.
The "Cursor" Solution: How seeking a specific ID makes queries almost instant.
Infinite Scroll Logic: Why social networks must use cursors to prevent duplicate or missing items when new data arrives.
