摘　　要：NUMA架构是目前最常见的一种多处理器架构,主要用来恢复故障或丢失的数据。对NUMA架构下内存数据库日志恢复技术进行研究,首先建立日志恢复马氏距离模型,从模型中诊断异常的数据;其次搭建内存数据库灰色关联度,目的是准确抓取故障,真实反映数据库演变的过程;最后创建了MMDB内存数据框架,利用这个框架明确数据恢复的流程,从而成功恢复内存数据库日志.The NUMA architecture is currently the most common multi-processor architecture, which is mainly based on the computer architecture and is commonly used to recover data that is faulty or lost. Research on memory database log recovery technology under NUMA architecture. First, establish a log recovery Mahalanobis distance model to diagnose abnormal data from the model, and then build the gray correlation degree of the memory database. The purpose is to accurately capture the fault and truly reflect the evolution of the database., Finally created the MMDB memory data framework, using this framework to clarify the data recovery process, so as to successfully achieve the memory database log recovery.
