Two-phase locking (2PL) is a fundamental and widely used concurrency control protocol. It regulates concurrent access to database data by following a specific sequence of lock acquisition and release during transaction execution, thereby ensuring transaction isolation. However, in strict 2PL, transactions must wait for...

Modern database management systems (DBMSs) evolve rapidly via frequent feature commits, yet validating each code delta within a 24-hour Continuous Integration (CI) budget remains an industrial challenge. Traditional manual regression testing is labor-intensive, while existing automated tools fall short: generation-base...

A novel architecture called S !"#$, designed to enhance the performance of hash indexes in disaggregated memory, is introduced and the results show that S !"#$ outperforms state-of-the-art DM-optimized hash indexes by at most 6.7 → (RACE), 3.6 → (SepHash), and 1.8 → (Outback) in YCSB workloads, respectively.
