Netflix recently expanded its load-shedding strategy, allowing service owners to prioritize API requests directly, improving resilience and operational efficiency during traffic spikes.
The prior load-shedding method treated all requests equally, leading to unnecessary availability reductions during high traffic. The new system prioritizes user-initiated requests to enhance user experience.
Netflix implemented a concurrency limiter to manage demand effectively. By focusing on user-initiated requests, they significantly improved service performance and maintained availability even under strain.
The decision to drop prefetch requests during outages was strategically implemented, as it minimized the impact on critical user requests, showcasing their efficient load-shedding capabilities.
