MLR: A Recovery Method for Multi-level Systems

Summary: MLR enables high concurrency in multi-level systems by replacing restrictive low-level locks with high-level locks at subtransaction commit, via compensation-based undo. It records high-level undo with the subtransaction commit in a single log, handling nested and multi-level transactions in a unified recovery framework. (summarized by gpt-5-nano on Feb 09 2026)
