Multiversion Query Locking

Summary: Multiversion Query Locking (MVQL) relaxes query-consistency relative to MV2PL to cut versioning cost while maintaining transaction-consistent views. A study shows MVQL outperforms MV2PL on query/update throughput and storage, with worst-case near MV2PL. (summarized by gpt-5-nano on Feb 09 2026)
