Abstract

The embodiment of the invention provides an image data storage method and device and a computer readable storage medium, and relates to the technical field of storage. The method comprises the following steps: responding to a storage request sent by image acquisition equipment, according to a mapping relationship between the image acquisition device and the virtual node and a mapping relationshipbetween a storage node and the virtual node, searching node information corresponding to a current storage node for storing data acquired by the image acquisition equipment, and feeding back the nodeinformation to the image acquisition equipment, so that the image acquisition equipment sends to-be-stored data to the corresponding storage node. Namely, through the established two-stage mapping relation, the problem of non-uniform load caused when storage nodes are newly added can be avoided, and the stability of the whole cloud storage system is ensured. Meanwhile, capacity equalization can bebetter achieved through rotation of the mapping relation between the storage nodes and the virtual nodes. And the whole storage process is more flexible.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to an image data storage method, device and computer-readable storage medium. Background technique [0002] With the development of communication technology, people's life has gradually entered the information age. While the information age has brought convenience to people's lives, there are also certain problems, such as the increasingly severe storage pressure. In order to alleviate the storage pressure, the storage method has also changed from the original centralized storage to the current popular distributed storage. [0003] The current distributed storage system can solve the pressure of data storage, but its storage mechanism still has defects. An efficient storage mechanism is very important to the flexibility and stability of the entire distributed storage system, especially the load balancing mechanism. Therefore, an efficient load balancing mechanism is urge...
