File storage method and device

Abstract

The invention discloses a file storage method and device. The method comprises the steps that by detecting directory attributes of storage files to be stored, whether the directory attributes are an aggregation attributes which are set according to application scenes in advance or not is judged; if yes, a file aggregation writing function is enabled, the storage files to be stored are stored to an aggregation file, when surplus storage space of OBJ objects in the aggregation file is equal to or smaller than a preset capacity, a plurality of storage files to be stored in the OBJ objects are written into a disk in batches, and the aggregation file comprises a plurality of OBJ objects; if not, the storage files to be stored are written into the disk. According to the file storage method and device, whether the directory attributes are the aggregation attributes or not is judged, so that it is determined that current files are file aggregation writing or ordinary non-aggregation writing, according to different scenes, the directory attributes are preset, and the file aggregation writing function is selectively enabled or disenabled so that the writing pressure of the cluster of the bottom layer can be reduced.

Description

technical field [0001] The invention relates to the field of file systems, in particular to a method and device for storing files. Background technique [0002] With the development of file system technology, the application of distributed storage file system is becoming more and more extensive. [0003] In a distributed storage file system, in order to cope with massive small file storage scenarios, small files are generally aggregated and written to the disk to reduce the number of times of writing to the disk and improve file writing performance. However, when the files are only large or the number is small, there is no need to use the file aggregation write function to realize file storage. [0004] When the files are large or the number is small, using the small file aggregate write function will make the writing pressure of the underlying cluster greater. Contents of the invention [0005] The purpose of the present invention is to provide a method and device for f...
