Dependence‐Cognizant Locking Improvement for the Main Memory Database Systems
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The traditional lock manager (LM) seriously limits the transaction throughput of the main memory database systems (MMDB). In this paper, we introduce dependence‐cognizant locking (DCLP), an efficient improvement to the traditional LM, which dramatically reduces the locking space while offering efficiency.

大数据, 2023 近数据计算范式驱动了银行、券商在全国或全球范围内建设多个数据中心。在传统的业务模式中，事务聚焦单个数据中心的数据访问。随着业务模式的变化，跨数据中心的分布式事务成为常态，例如，银行账户之间的转账、游戏账户之间的装备交换等，而这些账户的数据存储在不同区域的数据中心上。分布式事务处理需要两阶段提交协议来保证各参与节点子事务提交的原子性。在跨空间域场景下，节点之间的网络时延更长且存在差异性，传统的事务处理技术需要拓展，以保证系统能够提供较高的吞吐量。在分析了跨域事务存在的问题和优化空间后 ...
