摘要
本文提出了一种应用透明、低开销的检查点策略，用于在商用主存数据库(MMDB)系统中维护控制结构的一致性，该策略基于ARMOR (adaptive reconfigurable mobile object of reliability)基础结构。性能度量和可用性估计表明，所建议的检查点方案显著提高了数据库可用性(与基于主要恢复的解决方案相比，提高了9个百分点)，同时只产生很小的性能开销(在实际应用程序的典型工作负载中不到2%)。
Checkpointing of control structures in main memory database systems
This paper proposes an application-transparent, low-overhead checkpointing strategy for maintaining consistency of control structures in a commercial main memory database (MMDB) system, based on the ARMOR (adaptive reconfigurable mobile object of reliability) infrastructure. Performance measurements and availability estimates show that the proposed checkpointing scheme significantly enhances database availability (an extra nine in improvement compared with major-recovery-based solutions) while incurring only a small performance overhead (less than 2% in a typical workload of real applications).
