| 摘 要： | 提出了利用网络工作站(通过高速局域网络连接)内存加速内存数据库日志记录持久化的技术方案,在日志写入网络工作站的内存以后,事务即可提交,从而大大加快事务的提交过程.该方案综合运用了日志过滤、日志并行写入、检查点的日志应用等技术,提高日志写入和系统失败恢复的效率.试验证明,该技术方案在保证数据库系统可靠性的前提下,提高了恢复效率,而且提供恢复过程中的系统可用性.

| Abstract: | A proposal of logging to remote memory for main memory database systems is presented.After log records are written into remote memory,transactions could be committed,hence committing process is accelerated.Several techniques including log record filtering,parallel log writing,as well as log applying before checkpoint file writes are used to speedup log writing and reduce total recovery time.Experiment results show that the proposed scheme improves recovery efficiency and provides system availability during ... |
