Introduction to Pagination, Filtering, and Sorting

DodaTech Updated 2026-06-28 2 min read

In this tutorial, you will learn about Introduction to Pagination, Filtering, and Sorting. We cover key concepts, practical examples, and best practices to help you master this topic.

Pagination, filtering, and sorting are API patterns that allow clients to retrieve large datasets in manageable chunks, narrow results by criteria, and control the order of returned data.

What You'll Learn

You will learn why pagination, filtering, and sorting are essential, when to use each pattern, and how they work together for efficient data access.

Why These Patterns Matter

APIs that return all records at once crash under large datasets. A single request for 100,000 records consumes excessive memory, bandwidth, and processing time.

Pagination limits response sizes. Filtering reduces data transfer. Sorting ensures consistent ordering.

Real-World Use

DodaTech platforms handle millions of records. Doda Browser sync paginates bookmark lists, DodaZIP file browser filters archives by type and sorts by date, and Durga Antivirus Pro threat feed uses cursor-based pagination.

Common Mistakes

  1. No pagination at all — Returning unlimited records.
  2. No maximum limit — Allowing clients to request too many records.
  3. Inconsistent parameter naming — Different endpoints use different parameter names.
  4. Missing pagination metadata — Not telling clients about total pages or next cursor.
  5. No default sorting — Returning records in unpredictable order.

Practice Questions

  1. Why is pagination necessary for large datasets?
  2. How do filtering and pagination work together?
  3. What happens without default sorting?
  4. What metadata should pagination responses include?

Challenge

Analyze a public API's pagination implementation. Document their approach, parameters, response format, and identify any issues.

FAQ

What is the difference between offset and cursor pagination?

Offset pagination skips N records. Cursor pagination uses a pointer to a specific record. Cursor is more consistent for dynamic data.

How do I choose between pagination methods?

Use offset for small static datasets where users need page jumping. Use cursor for large dynamic datasets or real-time feeds.

Should I always include total count?

Include total for offset pagination. For cursor pagination, total is optional and expensive on large datasets.

What is the recommended maximum page size?

100 records per page is standard. Maximum should be 100-1000 depending on record size.

Mini Project

Design a pagination Strategy for a social media feed API with millions of posts. Choose between offset and cursor, define parameters, response format, and metadata.
