Zen: a High-Throughput Log-Free OLTP Engine for Non-Volatile Main Memory
Summary: Zen is a log-free OLTP engine designed for NVM-resident databases, addressing tuple-metadata updates, write redundancy, and space management via a metadata-aware cache, persistent transactions, and lightweight allocation. On Optane, it delivers up to 10.1× higher throughput with fast recovery. (summarized by gpt-5.6-luna on Jul 24 2026)
