At the risk of sparking off-topic debates about Netflix's content selections...are the same event streaming/data processing frameworks also used to detect trends and make actions on the content/frontpage side? Such as, detecting an anomalous spike of users watching some obscure movie in the last 24 hours, and then updating the "Trending Now" queues for users systemwide? Or is that something that happens (relatively) slow enough not to require an elaborate real-time framework?
