Discover how this innovative approach improves download speeds by 2-3 times compared to BitTorrent and previous static distribution trees. Understand the system's ability to handle over 800 petabytes of data daily, serving millions of client processes across 106 use cases with 55 different distribution policies. Gain insights into Owl's flexible policy interface, tracker sharding techniques, and the benefits of centralizing the control plane for scalability and customization.
