摘要
介绍了一个基于混合日志 (即逻辑日志与物理日志相结合 )的内存数据库恢复子系统 MDMRS的设计 .MDMRS有效地减少了事务日志信息量 ,缩短了系统恢复时间 .文中详细阐述了 MDMRS的事务处理、日志管理、基于分区的检查点 ,以及数据库恢复处理 ,最后对 MDMRS进行了性能分析 .
A main memory database recovery subsystem, (MDMRS), was presented. MDMRS is based on hybrid logging(a combination of logical logging and physical logging). Log data in MDMRS will be reduced, while the recovery time will be shorten. The transaction processing, log management and partition\|based checkpointing in MDMRS were discussed in detail. Finally, the performance analysis of MDMRS was given.
