Problems solved by technology

Picture or icon files usually occupy a small amount of storage space for a single file, but the number of files is huge, and corresponding huge index items need to exist in the global index, thus consuming a lot of memory

Embodiment Construction

[0064] In one embodiment, such as figure 1 Shown, a kind of distributed data storage method, comprises the following steps:

[0065] Step S102, acquiring a data resource and a data identifier corresponding to the data resource.

[0066] The data resources can be in the form of files, character strings, or data streams. The data identifier can be a string or a number, which is used to distinguish data resources. In one embodiment, the data storage request is obtained first, and the data resource and the data identifier corresponding to the data resource are extracted from the data storage request. In another embodiment, after the data resource is acquired, the data identifier corresponding to the data resource can be calculated according to the data resource.

[0067] For example, in a web application, a file upload request is obtained first, and then the file (data resource) and file name (data identifier) ​​are extracted from the file upload request. When the file is larg...

Abstract

A distributed data storage method comprises the following steps: acquiring data resources and data identification corresponding to the data resources; calculating the hash value of the data identification; calculating the page numbers of disk pages, corresponding to the data resources, in a memory unit according to the hash value and the block numbers of disk blocks in the disk pages; saving the data resources in the disk blocks of the corresponding disk pages according to the page numbers of the disk pages and the block numbers of the disk blocks. Besides, the invention provides a distributed data storage system. The distributed data storage method and system can reduce depletion of the internal memory and improve the storage efficiency.

Description

【Technical field】 [0001] The invention relates to the field of distributed storage, in particular to a distributed data storage method and system. 【Background technique】 [0002] Distributed storage is to disperse and store data resources on multiple independent devices, and each device is an independent storage unit for storing data. Traditional network storage systems use centralized storage servers to store all data resources. Storage servers become the bottleneck of system performance and the focus of reliability and security, which cannot meet the needs of large-scale storage applications. The distributed storage adopts a scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate and store information. It not only improves the reliability, availability and access efficiency of the system, but is also easy to expand. Usually when the amount of data reaches terabytes or even petabytes, data resources are sto...
