Zen: a High-Throughput Log-Free OLTP Engine for Non-Volatile Main Memory

Summary: Zen is a high-throughput, log-free OLTP engine for non-volatile main memory, tackling metadata and write management. Key ideas: metadata-enhanced tuple cache, log-free persistent transactions, and lightweight NVM space management; delivers up to 10.1x throughput and fast recovery on Optane DC PMem.
