Embodiment Construction

[0070] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0071] Based on the above problems, the present invention provides a write aggregation method for small files.

[0072] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the write aggregation method for small files in the present invention.

[0073] In this embodiment, the write aggregation method of the small file includes:

[0074] Step S10, the client initiates a small file write request;

[0075] In this embodiment, the file size of a small file is less than 1MB, and the client initiates a small file write request, and the client writes the content of the small file into the local cache of the client.

[0076] Step S20, the metadata server assigns a globally unique number ino and a unique storage area number ono to the small file;

[0077] After the client writes the content ...

Abstract

The invention discloses a write aggregation method and system for a small file. The write aggregation method comprises the following steps: initiating a write request of the small file by a client; assigning a globally unique number ino and a storage area unique number ono for the small file by a metadata server; calculating the aggregation position oid of the small file in an object storage device OSD by the client according to the ino and the ono; and aggregating the small file by the object storage device OSD according to the oid. The invention further discloses a read aggregation method for the small file and the client. The write aggregation and the read aggregation method and the system for the small file and the client provided by the invention can solve the problem of consuming more read time and write time of the small file.

Description

technical field [0001] The present invention relates to the technical field of distributed storage, in particular to a method and system for writing aggregation and reading aggregation of small files. Background technique [0002] With the development of cloud computing, mobile Internet and other technologies, the amount of data that needs to be stored and read is increasing, and the storage and reading methods of different data are different. For example, small files with only a few thousand bytes are widely used. Random aggregation, table lookup index for storage and reading. Due to the aggregation strategy, when small files are aggregated, it is necessary to create additional mapping tables for these small files, and read these small files by looking up the mapping table, so it takes a lot of time to read and write small files. Contents of the invention [0003] The main purpose of the present invention is to provide a small file write aggregation and read aggregation ...
