Offset, Cursor, and Keyset: Choosing the Right API Pagination Pattern

API pagination controls how list endpoints return data in manageable chunks, preventing slow responses and high memory use. Offset pagination is the simplest method, letting clients skip to any page, but it degrades in performance on large datasets and can return duplicates when data changes. Cursor pagination uses an encoded token pointing to a specific item, enabling stable and fast traversal of high-volume, frequently changing data. Keyset pagination works similarly but exposes the actual sort column value as the cursor, making it easier to debug while delivering the same performance gains. Choosing between the three depends on dataset size, how dynamic the data is, and whether clients need random page access.
