Metadata reading method, device, system and equipment

Abstract

The invention discloses a metadata reading method, device, system and equipment and a readable storage medium of a computer. The method comprises the following steps: receiving a request which is sentby a client and is used for reading metadata of a target file; determining a file related to the target file according to the target file of the request; reading the metadata of the target file and the metadata of the file related to the target file and buffering the metadata into the client. By adopting the method disclosed by the invention, the efficiency of reading the metadata of the file canbe improved and the metadata of a plurality of files is read in one step; a condition that the metadata of the file is repeatedly read can be avoided, the efficiency and performance of reading the file are improved, resources are saved and the efficiency of system operation is improved. Meanwhile, the metadata reading device, system and equipment and the readable storage medium of the computer, disclosed by the invention, also have the same technical effects.

Description

technical field [0001] The present invention relates to the technical field of file systems, and more specifically, to a method, device, system, equipment and computer-readable storage medium for reading metadata. Background technique [0002] With the rapid development and rise of the mobile Internet and the concept of big data, the amount of data that needs to be stored is growing exponentially, the explosive growth of data volume and the increasingly detailed data types, and the number of KB-level or even smaller files is also increasing. more. [0003] Currently, when reading files in a distributed file system, user processes and storage media are often distributed on different nodes, resulting in a long IO path. And every time you read a file, you need to access the metadata inside the cluster network, and you may even need to read the metadata across the network. Reading the metadata of the file across the network increases the delay of file reading. When the file is...

[0003] Currently, when reading files in a distributed file system, user processes and storage media are often distributed on different nodes, resulting in a long IO path

And every time you read a file, you need to access the metadata inside the cluster network, and you may even need to read the metadata across the network. Reading the metadata of the file across the network increases the delay of file reading.
