What is API pagination and why is it important?

API pagination is a method used to divide large sets of data into smaller, manageable chunks. It's important because it improves performance and user experience by reducing load times and making data retrieval more efficient.

How do I implement pagination in my API?

To implement pagination, you can use query parameters like 'page' and 'limit' to specify which set of data to return. For example, you might request 'GET /items?page=2&limit=10' to get the second page of results.

What are some common pagination strategies?

Common strategies include offset-based pagination, cursor-based pagination, and keyset pagination. Each has its pros and cons depending on the use case.

Can you give an example of cursor-based pagination?

Sure! In cursor-based pagination, instead of using page numbers, you use a unique identifier from the last item of the previous page as a cursor. For example, 'GET /items?after=lastItemId'.

What are the drawbacks of pagination?

Drawbacks include potential complexity in implementation, the possibility of missing data if items are added or removed during pagination, and user experience issues if not designed well.
