Optimizing OpenStack Swift for Small Object Storage in Video Streaming

iQiyi improved OpenStack Swift’s video‑streaming performance by redesigning its storage engine to merge numerous tiny objects into larger files, replacing Swift’s per‑object directory structure with RocksDB‑managed metadata, eliminating file‑ID overhead, using prefix scans for fast listings, and adding lazy deletion, achieving dramatic speedups with only about 3,000 lines of new code.
