Query Fresh: Log Shipping on Steroids
Summary: Query Fresh treats the replicated append-only log as the database, eliminating dual-copy storage and enabling parallel, nonblocking replay on NVRAM-backed standbys. It delivers synchronous safety and query freshness at scale: 4–5 replicas replay ~1.4 GB/s with only 4–6% primary overhead. (summarized by gpt-5.6-luna on Jul 24 2026)
