Embodiment Construction

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0058] See figure 1 , is a schematic structural diagram of an embodiment of the management system of the distributed database of the present invention; the management system includes: an existing node composed of at least two nodes (indicated as node A, node B, until node N in the figure) A queue, and at least one client (represented as client 1, client 2, and client N in the figure). Such as figure 1 As shown, the management system further includes: a management...

Abstract

The embodiment of the invention discloses a distributed database management method, which comprises: when receiving the configuration information of any new node, selecting a current node from a current node queue; triggering the new node and the selected current node to regulate a primary key item; and after the new node and the selected current node accomplishes the regulation of the primary key item, adding the new node into the current node queue, and triggering a client to update the node access list stored in the client. Correspondingly, the embodiment of the invention also discloses a distributed database management device and a distributed database management system. When the method, the device and the system of the invention are used, the distributed database can be managed automatically, the efficiency is high, the performance is high, the nodes can be added dynamically, and the expansion is easy.

Description

technical field [0001] The present invention relates to the technical field of databases, in particular to a management method, device and system of a distributed database. Background technique [0002] A distributed database refers to a database in which data is stored on each computer in a computer network. Computers located at different locations are also called "nodes" (also called "sites"), and each node is connected to each other through a communication network. Therefore, a distributed database can be regarded as a collection of nodes connected by a communication network. [0003] A database includes one or more database tables, and the primary key (Primary Key) is one or more fields in the table, and its value is used to uniquely identify a certain record in the table. In relational databases (distributed databases based on relational models, processing data in databases with the help of mathematical concepts and methods such as set algebra), in the relationship bet...
