Data storage method and device

Abstract

The invention provides a data storage method and device. The method comprises the steps: performing modulus operation of a preset numeric value on identification information of to-be-stored data, wherein the identification information is a numeric value, and the preset numeric value is the number of storage nodes; and storing the to-be-stored data into storage nodes corresponding to the result of the modulus operation. The data storage method and device overcomes the defect of slowing down data query caused by the continuous increasing of data volume in the prior art; the data is stored in a plurality of the storage nodes by means of the modulus operation; therefore, the to-be-queried data is positioned on one storage node by means of the modulus operation during data query, and the query scope is reduced, the data is further inquired in the storage node and the query efficiency is improved.

Description

technical field

[0001] The invention relates to the field of databases, in particular to a data storage method and device. Background technique

[0002] With the rapid development of the Internet, the amount of business data in enterprises is also increasing, and data storage and access methods have gradually become the focus of the industry. Traditional database systems manage data based on a single database. As the amount of data increases, the amount of data in the database will increase. When the amount of data reaches a certain level, the query on the data will gradually slow down, which will inevitably create a bottleneck in data access.

[0003] At present, there are some methods for sub-database and table division of the database. According to the logic, some data tables with relatively large data volume in the database can be divided out and placed in other data storage devices. For example, according to the data volume of the business type, Segment the data table...
