Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0034] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0035] In order to solve the problem of relatively low retrieval efficiency of metadata existing in the prior art, the embodiment of the present application cleverly proposes a metadata retrieval scheme. The server receives the retrieval request sent by the client, and the server receives the retrieval request according to The retrieval request is to retrieve ...

Abstract

Embodiments of the invention provide a metadata retrieval method and device, a storage medium and electronic equipment. The retrieval method is applied to a server in a distributed file system, and the server is configured with a database for caching metadata. The retrieval method comprises the steps of receiving a retrieval request sent by a client; retrieving target metadata corresponding to theretrieval request from a database according to the retrieval request; and sending information carrying the target metadata to the client. According to the embodiment of the invention, the metadata iscached in the database, so when the server receives the retrieval request sent by the client, the server can directly obtain the target metadata by querying the database, the interaction process between the server and the file system is reduced, and the retrieval efficiency of the metadata is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a metadata retrieval method, device, storage medium and electronic equipment. Background technique [0002] Due to its advantages in mass storage, the distributed file system is gradually replacing the traditional local file system in the Internet field. [0003] Currently, for a distributed file system without a metadata center, when file retrieval is required, the client sends the received metadata operation request to the server, and the server retrieves the data from the disk where each storage device brick is located. The required metadata is obtained from the local file system, and then the server sends the metadata to the client. [0004] In the process of realizing the present invention, the inventor found that the following problems exist in the prior art: when the existing server processes metadata operations, it needs to input / output (Input / Output, I / ...
