Data storage and reading method and device

Abstract

The embodiment of the invention provides a data storage method and device and a data reading method and device. The data storage method comprises the following steps that: interface equipment in a storage equipment group receives user data sent by a user through user equipment, and determines whether storage equipment group identification corresponding to user identification is in the presence in a first index or not, wherein each piece of user identification in the first index corresponds to one piece of storage equipment group identification; and if the storage equipment group identification corresponding to user identification is in the presence in the first index, storing the received user data into storage equipment in the storage equipment group with the storage equipment group identification. Since each piece of user identification in the first index corresponding to the storage equipment group identification, when data is stored through the first index, the user data of the same user is stored into the storage equipment of the same storage equipment group. By use of the method, data reading speed is improved, and user data can be more conveniently maintained.

Description

Technical field [0001] The present invention relates to the field of data processing technology, in particular to data storage and reading methods and devices. Background technique [0002] With the popularization and application of distributed storage systems, user data such as user identity information and user browsing records recorded on the website can be stored in different storage device groups. The prior art stores the user data of the same user in multiple storage device groups. For example, a storage device group is set up in area A and area B. When the user Zhang logs in to the website in area A, Zhang is here The user data generated during the second login process will be stored in the storage device group set in area A. When Zhang logs into the website in B area, the user data generated by Zhang during this login process will be stored in the storage device group set in B area. [0003] When all user data of a certain user needs to be read, the prior art needs to rea...

Problems solved by technology

[0003] When it is necessary to read all the user data of a certain user, the existing technology needs to read the user data of the user from different storage device groups respectively, and the data reading speed is also slow

At the same time, when it is necessary to maintain the user data of a certain user, it is necessary to maintain the user data in different storage device groups separately, which is not convenient enough
