An optimized deterministic concurrency control approach for geo-distributed transaction processing on permissioned blockchains [PDF]
Scientific ReportsConcurrency control is crucial for ensuring consistency and isolation in distributed transaction processing. Traditional concurrency control algorithms, such as locking-based protocols, usually suffer from performance degradation due to heavy transaction

Transparent Concurrency Control: Decoupling Concurrency Control from DBMS [PDF]
CoRR, 2019 For performance reasons, conventional DBMSes adopt monolithic architectures. A monolithic design cripples the adaptability of a DBMS, making it difficult to customize, to meet particular requirements of different applications. In this paper, we propose to completely separate the code of concurrency control (CC) from a monolithic DBMS. This allows us to

ACM Computing Surveys, 1998 Standard locking (two-phase locking with on-demand lock requests and blocking upon lock conflict) is the primary concurrency control (CC) method for centralized databases. The main source of performance degradation with standard locking is blocking, whereas transaction (txn) restarts to resolve deadlocks have a secondary effect on performance.

Adaptive Tip Selection for DAG-Shard-Based Federated Learning with High Concurrency and Fairness [PDF]
SensorsTo cope with the challenges posed by high-concurrency training tasks involving large models and big data, Directed Acyclic Graph (DAG) and shard were proposed as alternatives to blockchain-based federated learning, aiming to enhance training concurrency.

Contextual concurrency control [PDF]
Proceedings of the Workshop on Hot Topics in Operating Systems, 2021 Kernel synchronization primitives are of paramount importance to achieving good performance and scalability for applications. However, they are usually invisible and out of the reach of application developers. Instead, kernel developers and synchronization experts make all the decisions regarding kernel lock design. In this paper, we propose contextual

Concurrency Control and Consistency Over Erasure Coded Data
IEEE Access, 2022 For over a decade, erasure codes have become an integral part of large-scale data storage solutions and data-centers. However, in commercial systems, they are, so far, used predominantly for static data.
