API Pagination Techniques Explained 👇

When an API handles large datasets, poor pagination can quickly become a bottleneck

Four Common Pagination Methods

🔸Offset-based pagination: Relies on limit and offset parameters to paginate. Limit specifies how many items to return and offset defines where to start in the dataset.

🔸Cursor-based pagination: Instead of relying on numerical offsets, the server generates a cursor to identify the starting point for the next page. Ideal for datasets where new entries are frequently added or removed.

🔸Keyset-based pagination: Uses a stable key (e.g., ID, timestamp) to paginate efficiently in large datasets. This method bypasses row counting, improving speed and scalability.

🔸Page-based pagination: Retrieves data using a page parameter (e.g., ?page=3) to specify which subset of data to return. It’s simple and intuitive but less effective in datasets that change frequently.

How to Implement Pagination in Your API

🔹Offset-based Pagination: GET /items?limit=10&offset=20This request returns 10 items starting from the 21st record.

🔹Cursor-based Pagination: GET /items?cursor=abc123The server provides a cursor like abc123 for the next page, allowing precise control over the data flow.

🔹Keyset-based Pagination: GET /items?after_id=100This request retrieves items where the ID is greater than 100, efficiently leveraging indexed fields.

🔹Page-based Pagination: GET /items?page=3Fetches the third page of results, with each page containing a predefined number of items.

Avoid These 3 Common Pagination Mistakes

▪️Neglecting the last page: Ensure your API returns a clear response when users reach the final page of data.

▪️Failing to account for real-time data: Use cursor-based or keyset-based pagination to avoid issues with missing or duplicated records in dynamic datasets.

▪️Ignoring documentation: Clearly explain your pagination parameters (limit, offset, cursor, page) in your API documentation to avoid confusion.

Best Practices

✅Optimize database queries: Use indexes on fields you paginate (e.g., ID, timestamp).

✅Set a maximum page size: Protect your system by capping the number of items per page.

✅Validate pagination parameters: Ensure limit and offset values are valid to prevent errors.

✅Consistency across endpoints: Keep pagination formats uniform to maintain ease of use and prevent confusion.

What’s the biggest mistake you’ve seen in API pagination?

CI/CD pipelines — How do you optimize their performance?

The first step in optimizing any system is to analyze its processes and identify the bottlenecks and inefficiencies.

A common culprit and one of the most impactful factors for CI/CD pipeline performance is build times.

Whether it's local development or CI/CD pipelines, we've all experienced the pains of slow build times.

But there is a simple solution.

Optimize your build process with a caching tool.

Depot Cache is a tool that I've been very impressed with.

— It caches and reuses build artifacts, saving time across local development and CI/CD pipelines.

— Up to 1,000% faster builds

— Integrates with almost any CI tool (eg; GitHub Actions, Jenkins, etc)

— Globally distributed caching ensures fast, consistent performance from anywhere

By eliminating redundant work, Depot Cache speeds up builds dramatically and reduces compute time in CI/CD environments.

The result? Faster pipelines that lower cloud costs.

Not to mention a better developer experience and more time for better uses than waiting for builds to finish!

It's super simple as well. Simply configure an endpoint and a token, and your builds are ready to go — locally and in your pipelines.

Depot is free to try. Our link will give you a month for free.

Another common cause of poor performance is the lack of parallelism. Identify processes running in sequence and determine if they can run in parallel.

The order of test execution also impacts performance. Balance early feedback with efficiency, and where possible, run only tests relevant to the changes—but avoid overcomplicating your test suite.

Lastly, ensure your infrastructure can support the pipeline with adequate resources and scalability.

An optimized CI/CD pipeline is crucial for productivity, so invest time to ensure it runs smoothly and efficiently.

Why is Redis so 𝐟𝐚𝐬𝐭?

The diagram below shows 3 main reasons:

1️⃣ Redis is RAM-based. Access to RAM is at least 1000 times faster than access to random disks. Redis can be used as a cache to improve application responsiveness and reduce database load when used as a cache.

2️⃣ Redis implements IO multiplexing and single-threaded execution.

3️⃣ A number of efficient lower-level data structures are leveraged by Redis. By keeping these data structures in memory, serialization and deserialization costs are reduced.

SortedSet, for example, makes the implementation of leaderboards so simple and efficient. On the other hand, a bitmap can be used to aggregate month-over-month login statuses.

Over to you: What do you use Redis for in your projects?
