Bookmarking—the feature that lets viewers pick up exactly where they left off—is one of the most data-intensive services inside Sky’s global streaming platform. With 20,000+ writes per second and massive spikes during binge-watching, their Cassandra-based system proved costly and difficult to scale. In this session, Sky shares how migrating bookmarking to Redis Cloud delivered cross-region replication, ultra-low latency, and dynamic scaling under heavy load.

1. Sky’s migration from Cassandra to Redis Cloud for reliable global bookmarking.
2. How Redis handles 20,000+ writes per second with low latency.
3. Demonstrates cross-region replication and dynamic scaling during peak streaming demand.
