Umbra: A Disk-Based System with In-Memory Performance
Summary: Umbra adapts HyPer into an SSD-backed DB that delivers in-memory performance for the cached working set while scaling to SSD storage. Key innovation: a low‑overhead buffer manager with variable-size pages and memory‑optimized techniques to handle uncached data gracefully. (summarized by gpt-5-mini on Feb 09 2026)
