Abstract

The invention provides a memory database, and relates to the technical field of databases, the memory database comprises a memory data storage unit, a configuration switch, a memory data modification management unit and a memory data query unit, the memory data storage unit is used for data storage; the configuration switch is used for memory configuration, that is, the configuration switch is used for connecting a plurality of server memories of the distributed cluster with the memory data storage unit; the memory data modification management unit is used for newly adding, modifying, deleting and updating management of memory data; and the memory data query unit is used for querying memory data. The method solves the problems that in the prior art, a memory database cannot achieve data recording, cannot support addition, deletion and modification in a memory, and cannot support query and SQL condition query; Meanwhile, the problem that a normal database cannot be synchronized to a memory database cannot be supported is solved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to an in-memory database. Background technique [0002] In-memory database, as the name implies, is a database that puts data in memory and operates directly. Compared with disk, the data read and write speed of memory is several orders of magnitude higher. Saving data in memory can greatly improve the performance of applications than accessing it from disk. [0003] The in-memory database abandons the traditional way of disk data management, redesigns the architecture based on all data in memory, and makes corresponding improvements in data caching, fast algorithms, and parallel operations, so the data processing speed is faster than that of traditional databases. The data processing speed is much faster, generally more than 10 times. The biggest feature of the in-memory database is that its "primary copy" or "working version" is resident in memory, that is, active transactions...
