基于磁盘数据库的存储集群由于内外存交换开销过大,无法支撑数据的实时存储与处理,因此使用基于内存数据库的存储集群成为目前很多业务数据存储的设计方案。本文主要研究了基于内存数据库的存储集群中的数据库代理、单点故障恢复等关键技术。
Storage cluster which based on disk resident database are unable to store and process data in real time due to considerable overheads caused by I/O swapping operations. Therefore storage cluster which based on memory database are a better design proposal. This paper mainly studies the key technologies of the storage cluster which based on memory database including database proxy, the single node recovery.
