Episode notes

Lucas and Luna dive into the limitations of traditional pagination for real-time APIs. Using the example of a stock-price feed that updates every second, Lucas explains how offset-based pagination fails when data changes between requests. He introduces cursor-based pagination with a unique, time-ordered key and explains why it avoids duplicates and gaps in volatile datasets. Luna questions the implementation complexity and caching implications. The episode also touches on combining async pagination with WebSockets for live streams, and the trade-off between consistency and throughput. A focused, practical episode for developers building data-intensive APIs. #AsyncPagination #CursorBasedPagination #RealTimeAPI #APIDesign #DataConsistency #WebSockets #PaginationStrategy #OffsetVsCursor #LiveDataStreams #APIReliability #BackendEngineering #DeveloperTools #BusinessAndTechnology #FexingoBusiness #BusinessPodcast #LucasAndLuna #APIPatterns #TechDeepDive Keep every episode free: buymeacoffee.com/fexingo
