Research on Memory Database Failure Recovery Strategies
摘要
Abstract
Memory database exists in volatile memory, and the data is easy to lose, thus failure recovery com- ponent is crucial. Considering the constraints of system environment, this paper designs a kind of system recovery model which combines log with shadow page technique, discusses the implementation methods of log protocol, fuzzy checkpoint strategy, reload algorithm, and restore technology and so on. This method does not need addition- al hardware support, and with the advantages of few log record numbers, checkpoint and transaction process paral- lel execution, quickly reload and recovery process, it greatly enhances the recovery efficiency of memory database.关键词
