Concurrency Control in Graph Protocols by Using Edge Locks
Summary: Separate item-level exclusive locks from precedence control by introducing edge locks and a transformation that maps any graph locking protocol to an equivalent edge-lock protocol preserving correctness. Characterize a broad class subsuming prior graph schemes, show increased concurrency and unify deadlock-avoidance techniques. (summarized by gpt-5-mini on Feb 09 2026)
