Translytical Processing via DB-OS Co-designed Buffer: Cross-Engine Isolation and Tunable Update Visibility for HTAP
Summary: Vista co-designs the DB and OS buffer to share immutable, huge-page-backed segments between PostgreSQL OLTP and DuckDB OLAP, isolating writes from scans. Sealing policies tune update visibility, achieving up to 12.8× speedups over baselines. (summarized by gpt-5.6-luna on Jul 26 2026)
