Skippy: a New Snapshot Indexing Method for Time Travel in the Storage Manager
Summary: Skippy: a new snapshot index for page-level, copy-on-write snapshots in storage managers, enabling time-travel queries in general-purpose DBs. Efficient, low-cost access to old snapshot ranges with online iteration comparable to recent snapshots. (summarized by gpt-5-nano on Feb 09 2026)
