Verification scope: official USENIX OSDI 2022 paper page/abstract.
Research question: How can a private cloud distribute large, hot objects at very high fanout while supporting diverse per-use-case policies?
Context: Meta needed one distribution service for millions of client processes and heterogeneous workloads.
Method: Owl combines ephemeral peer-to-peer distribution trees in a decentralized data plane with centralized tracker services. Trackers maintain peer/cache/download metadata, choose fetch sources and retries, control caching/eviction, and expose a configurable policy interface; peers remain simple state machines.
Evaluation/results: USENIX reports more than 800 PB distributed per day, 2–3× faster downloads than BitTorrent and Meta’s prior decentralized static tree, and production support for 106 use cases using 55 policies.
Interpretation: Centralizing control decisions need not prevent data-plane scalability when bulk transfer remains peer-to-peer.
Applicability/limits: Most directly applicable to high-fanout object distribution inside a managed private cloud. The official abstract does not establish equivalent behavior on open or adversarial networks.
