Problems solved by technology

[0007] 1. File data is imported in units of file groups. There may be hot data and cold data in the file group. This will import hot data into EC storage mode for storage, affecting the high concurrent access efficiency of files. EC storage mode Frequent access of data will cause a great burden on system resources
[0008] 2. The file data in the EC storage mode cannot be deleted directly. If the file group where the file data is located has been imported into the EC storage mode, the file data cannot be deleted directly, which will affect the file management

Embodiment Construction

[0079] In order to make the purpose, technical solutions and advantages of the embodiments of this paper clearer, the technical solutions in the embodiments of this paper will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this paper. Obviously, the described embodiments are the Some, but not all, embodiments. Based on the embodiments herein, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the scope of protection herein. It should be noted that, in the case of no conflict, the embodiments herein and the features in the embodiments can be combined arbitrarily with each other.

[0080] In most distributed storage, multi-copy data generally puts multiple file data in a file group. The storage capacity of the file group is fixed (such as 10GB). When the data in the file group exceeds the capacity of the file group, the file group Set it to the read-onl...

Abstract

The invention relates to a data storage method and device. The invention relates to the field of computer internet, and solves the problem that access is affected when a file group is used as a whole to convert a file from a multi-copy type to an EC type for storage. The method comprises the following steps: re-determining the storage type of data according to the accessed condition of the data; and storing the data according to the re-determined storage type. The technical scheme provided by the invention is suitable for a distributed storage system, and data storage management adapting to access requirements is realized.

Description

technical field [0001] This article relates to the field of computer internet, in particular to a data storage method and device. Background technique [0002] The data heat in distributed storage is different, resulting in differences in the frequency of data access. Data with high access frequency is usually called hot data, and data with low or even almost no access frequency is called cold data. [0003] Based on the different access requirements of hot and cold data, hot data is generally stored in multiple copies to meet the high concurrent access of files, and cold data can be stored in EC (Erasure Code, that is, erasure code) cold storage to reduce storage costs , considering the limited storage resources, it is necessary to import data from multi-copy storage to EC storage to save resources. [0004] In distributed storage, multi-copy data is stored by storing K redundant copies of file data, and K copies are distributed in storage devices with specified fault iso...
