API Pagination Explained: Offset vs. Cursor (The Performance Secret for MILLIONS of Records)

Is your API database hitting a wall? Learn the secret to handling millions of records without a server crash!

In this quick, high-impact video, we break down the two main approaches to API pagination, a critical concept in web development and backend engineering. Pagination is simple in theory: sending large datasets in small, manageable chunks—but the implementation can make or break your application's performance.

We dive into a direct comparison between:

Offset Pagination (The Simple Way): Using parameters like page and limit to skip previous records. We show why the classic SQL OFFSET...LIMIT query works well for small databases but becomes incredibly slow and inefficient as you scale to thousands of pages.
Cursor Pagination (The Scalable King): Discover how using a unique identifier (a 'cursor' or 'keyset') from the last record to fetch the "next batch" offers near-instantaneous query performance. Learn why this technique is the gold standard for high-traffic, massive databases, offering superior scalability and speed.
Whether you're a student learning API design, a developer prepping for a technical interview, or a backend engineer optimizing production code, this 40-second punchline will clarify when to use Offset Pagination and when Cursor Pagination is the only choice.

Code smart, paginate smarter!
