Abstract

The invention discloses a processing method and device for a database. The method comprises the steps of obtaining a first instruction used for recovering a database; obtaining first database entry identification information of a first page in a first storage medium according to the first instruction; according to the first database entry identification information, a first data storage structureused for managing the first storage medium is obtained, the first data storage structure comprises a second page, and the second page comprises second database entry identification information; and performing recovery processing on the database according to the first instruction and the first data storage structure. By adopting the method provided by the invention, the problem of low memory processing performance of the database in the nonvolatile memory in the prior art is solved.

Description

technical field [0001] The present application relates to the field of data storage, and in particular to a processing method and device for databases. Background technique [0002] In order to ensure that data will not be lost, the current memory database will back up the data in the memory to the disk. Because the introduction of backup operations and I / O operations will greatly reduce the efficiency of the memory database. The non-volatile memory (NVM, Non-Volatile Memory) that has appeared in recent years has the characteristics of no loss of data when power is turned off, byte addressability, and fast read and write speed. Deploying the memory database on NVM can greatly improve the performance of the database. efficiency. [0003] In the NVM database scenario, there are the following backgrounds: there is a direct relationship between allocated objects, such as referencing each other in the form of pointers; the performance requirements for the allocator are high; th...
