Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] In the embodiment of the present invention, users are evenly distributed to different node databases according to the user distribution weights of different node databases in the current system.

[0024] As an embodiment of the present invention, the corresponding user distribution weight can be determined according to the number of distributed users in the node database, and the users can be evenly distributed to different node databases.

[0025] First, record the number of distributed users in the system, and the number of distributed users on each node database.

[0026] In the embodime...

Abstract

The invention applied to the computer field provides a distributed database system in the distribution of users, devices and systems. Including the following steps: access to the current system of different users of the database node weights according to the current system different users of the database node weights will be a balanced distribution of the different users of the node database; keep users distribution of user information, which covers the distribution of information users have already been distributed users include user identification information. The user identifies information with the stated where the corresponding user identification information database nodes. Implementation of this invention in the light of the current system of different users of the database node weights will be distributed to the different users of the node database, enables users to a balanced distribution of data in the user data upgrade or relocate, affects only the upgrade or migration users will not affect other users of data access, database can improve speed and efficiency.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a user distribution method, device and system in a distributed database system. Background technique [0002] A distributed database system is a collection of data that logically belongs to the same system and is physically distributed on multiple nodes (nodes) connected by a computer network. The nodes are connected together in the communication network, and each node is an independent database system with its own database, central processing unit, terminal, and its own local database management system. In a distributed database system, user data is generally distributed in different node databases (DB) according to users. Every time you access or modify user data, you need to locate the node database where the user data is located, and locate the node database information where the user data is located. It is the important state data of the user. [0003] At present, when...
