How should pagination and API versioning work?
Practice this questionWANT TO UNDERSTAND THE CONCEPT FIRST?Learn How should pagination and API versioning work?
Definition:
Pagination divides a large result set into manageable pages, while API versioning lets an interface change without unexpectedly breaking clients. Both are part of the API contract because callers depend on ordering, limits and field meaning. A good design remains predictable as the data and number of clients grow.
Key points:
-
Limit page size and use a stable sort order.
-
Offset pagination is simple; cursor pagination works better for deep or changing lists.
-
Version breaking API changes, for example with
/v2, and plan old-client support. -
For cursor pagination, use a deterministic order with a unique tie-breaker and validate the cursor.
Interview point:
- Describe how a client gets the next page and what happens when records are inserted between requests.
