Embodiment Construction

[0045] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0046] The present invention aims at the problem that the existing data storage cannot be expanded after reaching the peak, and provides a method for distributed data storage, which is applied to a distributed data storage system, and the distributed data storage system includes a client, a master node and a slave node . Such as figure 1 Shown, embodiment method of the present invention comprises:

[0047] Step 101, the client acquires the data to be stored, and sends the data to be stored to the master node.

[0048] In a feasible implementation manner, when a user wants to store data, the data to be stored can be imported into the client and uploaded to other nodes in the distributed data storage system through the client.

[0049] In the embodiment...

Abstract

The invention relates to the technical field of data processing, in particular to a data distributed storage method and a distributed data storage system. The method is applied to the distributed data storage system. The distributed data storage system comprises a client side, a master node and slave nodes, and the method comprises the steps of enabling the client side to obtain to-be-stored data and stores the to-be-stored data; sending the data to be stored to the master node; using the master node for segmenting the data to be stored and storing the segmented data; enabling the master node to change the to-be-stored data as a change log and sends the change log to the slave node; enabling the slave node to carry out segmentation on the change log; and enabling the slave node to store the segmented log data. Based on the invention, the reliability and availability of the database can be improved, and the risk of database change and maintenance can be dispersed.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for distributed data storage and a distributed data storage system. Background technique [0002] In recent years, databases for traditional application services often face two technical difficulties. [0003] 1) Database connection bottleneck: When the service continues to expand, the number of connections between the application server and the database gradually increases, and the number of connections will reach a bottleneck as the application server continues to expand. [0004] 2) Database storage bottleneck: When the demand for data storage increases, the storage needs to be continuously expanded. At this time, the cost of data storage increases, and the storage specification cannot be expanded after reaching the peak, encountering a storage bottleneck. Contents of the invention [0005] The invention provides a data distributed storage method and a dist...
