Explain with highlit
I use PageNumberPagination for simple, bookmark-friendly pagination and CursorPagination when data changes frequently (prevents duplicate/missing items between pages). Creating a custom pagination class lets me control page_size, page_size_query_param, and max_page_size. I return metadata like count and next/previous URLs in the response. For APIs with heavy queries, I cache total counts or estimate them. Cursor pagination is stateless and efficient but doesn't support jumping to arbitrary pages. I choose based on use case.
