Staring into the Abyss: An Evaluation of Concurrency Control with One Thousand Cores

Summary: Evaluation of seven CC algorithms on a main-memory DBMS scaled to 1024 cores reveals universal scalability bottlenecks as core counts rise. Incremental fixes fail; bottlenecks persist, arguing for a DBMS redesign tightly coupled to hardware. (summarized by gpt-5-nano on Feb 09 2026)
