M. David Allen, a seasoned software engineer and entrepreneur, presents a tutorial on using the beer-sample dataset in Couchbase to illustrate efficient data pagination techniques. He explains the need for paging in applications, particularly when managing large datasets, using a hypothetical beer-rating app as an example. By implementing pagination, only a subset of data is sent to the user's browser, enhancing performance and user experience. The tutorial details the use of N1QL clauses—LIMIT, OFFSET, and ORDER BY—to achieve this, providing SQL-like query examples to retrieve and display data in manageable portions. Allen also addresses how to determine the number of pages in a dataset and the behavior of queries when requesting non-existent pages, highlighting the efficiency and practicality of these methods for applications and API endpoints.
