TxForest: A DSL for Concurrent Filestores [PDF]
arXiv, 2019 Many systems use ad hoc collections of files and directories to store persistent data. For consumers of this data, the process of properly parsing, using, and updating these filestores using conventional APIs is cumbersome and error-prone. Making matters worse, most filestores are too big to fit in memory, so applications must process the data ...

Advanced Science, EarlyView.A 3D printed sodiophilic rGO/diamane microlattice aerogel with uniform ions flux and exceptional sodiophilic features is demonstrated as a stable host for sodium metal anode. The sodiophilic diamane nanoflakes regulate the uniform deposition of metallic Na with a dendrite‐free deposition morphology, achieving an ultra‐high areal capacity of 78.60 mAh ...

Improving High Contention OLTP Performance via Transaction Scheduling [PDF]
arXiv, 2018 Research in transaction processing has made significant progress in improving the performance of multi-core in-memory transactional systems. However, the focus has mainly been on low-contention workloads. Modern transactional systems perform poorly on workloads with transactions accessing a few highly contended data items.

High-Performance Concurrency Control Mechanisms for Main-Memory Databases [PDF]
Proceedings of the VLDB Endowment (PVLDB), Vol. 5, No. 4, pp.
298-309 (2011), 2011 A database system optimized for in-memory storage can support much higher transaction rates than current systems. However, standard concurrency control methods used today do not scale to the high transaction rates achievable by such systems. In this paper we introduce two efficient concurrency control methods specifically designed for main-memory ...

Concurrency Protocol Aiming at High Performance of Execution and Replay for Smart Contracts [PDF]
arXiv, 2019 Although the emergence of the programmable smart contract makes blockchain systems easily embrace a wider range of industrial areas, how to execute smart contracts efficiently becomes a big challenge nowadays. Due to the existence of Byzantine nodes, the mechanism of executing smart contracts is quite different from that in database systems, so that ...
