Rest API - Pagination Patterns

What is the main advantage of using keyset pagination over traditional offset-based pagination in REST APIs?

AIt requires less server memory by caching all pages in advance.

BIt allows jumping to any page number directly without sequential access.

CIt improves performance by avoiding slow offset queries on large datasets.

DIt automatically sorts data in descending order without extra code.

Step-by-Step Solution

Solution:

Step 1: Understand offset-based pagination issues
Offset pagination uses a page number and offset, which becomes slow on large datasets because the database must skip many rows.
Step 2: Recognize keyset pagination benefits
Keyset pagination uses a fixed key (like an ID) to fetch the next set of rows, avoiding the costly skip operation and improving performance.
Final Answer:
It improves performance by avoiding slow offset queries on large datasets. -> Option C
Quick Check:
Keyset pagination = better performance [OK]

Quick Trick: Keyset uses keys, not offsets, for faster queries [OK]
