  • Netflix replaced its CQRS implementation with RAW Hollow, an in-memory object store, for Tudum's architecture.
  • The initial CQRS setup used Kafka and Cassandra but faced delays in content preview due to caching refresh cycles.
  • RAW Hollow provides strong read-after-write consistency and reduces data size by 75% through compression.
  • The new architecture eliminates cache invalidation issues and significantly improves page rendering speed.
  • Tudum's revamped system benefits both editors (faster previews) and visitors (faster page loads).
