FastAPI & Next.js project: Flight Booking App With DevOps. Day 1 - 100 - Why Limit/Offset Fails at Scale | System Design: Cursor Pagination | Flight Booking Engine | Day 71

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.
