DEADLOCK-FREEDOM (AND SAFETY) OF TRANSACTIONS IN A DISTRIBUTED DATABASE (Extended Abstract)
Summary: Shows deadlock-freedom checking for lock-based transactions in distributed DBs is coNP-complete even for two transactions, contrasting polynomial centralized case. Gives poly-time algorithms when number of sites is fixed, and for safety/deadlock with fixed #transactions. (summarized by gpt-5-mini on Feb 09 2026)
