摘要
高效的锁机制是影响内存数据库性能的重要因素,也是MMDB设计中需要重点考虑的部分。因此,国内外开展了许多关于锁机制方面的研究。文中列举了三种锁机制,它们根据各自的应用背景和需求出发,分别从锁的粒度、管理器和恢复策略上对锁机制进行改进,从而在各自的应用中大幅提高了并发控制的效率。
The efficiency of a lock scheme is one of the important aspects of implementation of main memory database system.For this reason, a wide range of approaches for achieving efficient locking has been taken in MMDB research. In this paper,an overview of three approaches is presented. These approaches achieve their goals in the best possible way according to their different application background.
