Problems solved by technology

However, after merging multiple small files into one large file, the retrieval efficiency for small files is very low. If you want to view some attributes and contents of small files, you need to take the small files out of the large file, and even some methods will Large files are then separated into multiple smaller files

Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] figure 1 Shows a structural block diagram of a small file storage system in a specific embodiment of the present invention, the storage system mainly includes a large file creation module 11 and a small file storage module 12, wherein:

[0048] Large file creation module 11 is used to create a large file; Described large file comprises index area offset storage area, small file storage area and small file index information storage area; Index area offset refers to the small file index information The relative offset of the starting position in the entire large file; the index information of the small file includes information such as the file name, file size, file metadata information, and the relative offset of the small file in the large file.

[0049] Small file storage module 12 is used for merging small file into the smal...

Abstract

The invention discloses a small file storage, query and deletion method and system. The method comprises the following steps: firstly, creating a large file and merging a small file into a small file storage area of the large file; during the query of the small file, querying the index information of the small file according to the offset of an index area and the file metadata information of the small file; obtaining the small file stored in the large file according to the relative offset, in the large file, of the small file in the small file index information. Through the method and system provided by the invention, the small file can be rapidly positioned according to the metadata information of the small file, so that the searching and processing efficiency of the small file in the large file is effectively improved.

Description

technical field [0001] The invention relates to the field of file processing, in particular to a method and system for storing, querying and deleting small files. Background technique [0002] With the development of informatization, there are more and more files, especially for industries such as finance. It is necessary that these small files cannot be deleted, but the difficulty of small file management and backup is increasing. [0003] At present, the general solution for small file management and backup is to merge them into one large file (a large file generally refers to a file with a large file size, such as several GB, tens of GB), and merge multiple small files into one large file for storage. This pressure can be effectively relieved, but this simple combination is very inconvenient for file query and retrieval. When merging multiple small files into one large file, create a file index table, which contains description information of multiple dimensions for eac...
