MD-MVCC: Multi-version Concurrency Control for Schema Changes in Azure SQL Database

Summary: MD-MVCC brings snapshot-isolated, multi-version schema changes to Azure SQL, allowing concurrent queries to use the prior schema without synchronization. End-to-end versioning—from execution and caches to persisted metadata—minimizes disruption without performance overhead. (summarized by gpt-5.6-luna on Jul 24 2026)
