Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] figure 1 It is a flow chart of the method for realizing small file access in the present invention, such as figure 1 shown, including the following steps:

[0027] Step 101, detecting the size of the written file.

[0028] The file system provides corresponding functions to realize how to detect the size of the written file, which is common knowledge well known by those skilled in the art, and will not be repeated here.

[0029] Step 102, comparing the size of the written file with a predetermined threshold, when the size of the written file is less than or equal to the given threshold, the data written into the file is stored in the data structure inode, and in the In the inode, the flag bit is added to be 1; otherwise, the written file is stored in the data block pointed to by the inode, and the flag bit is added to the inode to b...

Abstract

The invention discloses a method and a device for realizing small file access. The method includes: detecting the size of a written file; comparing the size of the written file with a preset threshold, and when the size of the written file is smaller than or equal to the set threshold, storing data of the written file in a data structure inode, and adding a zone bit 1 in the inode; otherwise, storing the written file in a data block pointed by the inode, and adding a zone bit 0 in the inode; reading the data of the written file according to the zone bit in the inode. By the method, speed of small file storage and reading is increased greatly.

Description

technical field [0001] The invention relates to computer storage technology, in particular to a method and device for realizing small file access. Background technique [0002] Small files generally refer to files below 1MB. The storage and reading of a large number of small files has always been a difficult problem for the storage system, especially with the development of computer technology, there will be more and more data. [0003] The existing technology generally stores data in this way: first create a data structure (inode), each inode is unique, and points to a data block respectively, and stores the data written into the file in this data block, the inode and the data block It is one-to-one correspondence. Most of the current file systems do not treat small files and large files differently, that is, they do not distinguish according to the size of the file, and they are all stored and read in the same way. This makes a large number of random reads and writes of...
