Abstract

The present application discloses a method, device, device and medium for updating metadata, including: when an update instruction is received, acquiring the target level corresponding to the target metadata corresponding to the update instruction, and The corresponding updated metadata is cached to the internal memory of the server where the target SSD is located; wherein, the target metadata is the metadata in which the metadata in the data file in the target SSD is graded in advance according to the update frequency of the attribute information of the metadata; and, the data The metadata belonging to the same level in the file is centrally stored in the target SSD; and it is judged whether the update metadata meets the preset update condition; if so, the update metadata is written to the target SSD. Obviously, since this method can greatly reduce the number of times to modify the target SSD due to metadata update, it can significantly improve the service life of the target SSD.

Description

technical field [0001] The present invention relates to the technical field of cloud computing data centers, and in particular, to a method, device, device and medium for updating metadata. Background technique [0002] In the field of cloud computing data centers, the performance and security of data storage have always been the core concerns of users. At present, SSD (Solid State Disk, solid state drive) has the advantages of high performance, low power consumption and not easy to be damaged, so it has become a popular choice in the field of data storage. [0003] In the prior art, the data files stored in the SSD are usually composed of file data and file metadata, and the file metadata in the data files are all stored in the SSD as byte-level small data files. In this case, when the target metadata in the data file needs to be updated, since the logical block storing the target metadata cannot be overwritten in the original position, it can only be updated on the new lo...
