FafnirDT: Dynamic Timestamp in Lock-based Concurrency Control Protocols FafnirDT: Dynamic Timestamp in Lock-based Concurrency Control Protocols Ryuichi, Lun Tatsuhiro, Nakamori Lianne, Cagalingan Hideyuki, Kawashima Ryuichi, Lun Tatsuhiro, Nakamori Lianne, Cagalingan Hideyuki, Kawashima 並行性制御 Scalability stands as an imperative consideration within the realm of database management, especially among concurrency control protocols tasked with parallel execution. Despite its acknowledged importance, lock-based concurrency control protocols such as 2PL wait-or-die often encounter scalability issues, especially under high workloads. To overcome these challenges, we propose FafnirDT, a novel method integrating an elastic reader-writer lock with a dynamic timestamp tracker. This innovative approach is designed to efficiently manage resource contention in demanding parallel execution environments with many-core architecture, with an emphasis on its effectiveness during long transactions.
