Merge's blog post discusses the concept and application of keyset pagination, a method of API pagination that uses a key, such as an ID or timestamp, to efficiently retrieve data in manageable chunks. This approach is highlighted as beneficial for saving bandwidth and maintaining consistent performance, as it allows for progressive data retrieval without skipping records. However, keyset pagination can be complex when dealing with volatile datasets or when there's a need to skip certain data points. The post also contrasts keyset pagination with other pagination methods like offset pagination and cursor pagination, explaining their differences in handling data retrieval and position tracking. To simplify integration and avoid dealing with individual API providers’ requirements, Merge offers a Unified API solution that manages authentication, rate limits, and pagination, allowing scalable integration builds across various software categories.
