Abstract

The invention discloses a metadata updating method and device, equipment and a medium, and the method comprises the steps: obtaining a target level corresponding to target metadata corresponding to anupdating instruction when the updating instruction is received, and caching the updating metadata corresponding to the target metadata to a memory of a server where a target SSD is located, wherein the target metadata is metadata obtained by grading metadata in a data file in the target SSD in advance according to the updating frequency of attribute information of the metadata, and the metadata belongs to the same level in the data file is stored in the target SSD in a centralized manner; judging whether the updating metadata reaches a preset updating condition or not; and if yes, writing theupdated metadata into the target SSD. Obviously, due to the fact that the method can greatly reduce the frequency of modifying the target SSD due to metadata updating, the service life of the targetSSD can be remarkably prolonged.

Description

technical field [0001] The present invention relates to the technical field of cloud computing data centers, in particular to a method, device, equipment 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 issues that users care about. Currently, an SSD (Solid State Disk, solid state drive) has the advantages of high performance, low power consumption, and not easily damaged, thus becoming a popular choice in the field of data storage. [0003] In the prior art, a data file stored in an SSD is usually composed of file data and file metadata, and the file metadata in the data file is stored in the SSD as a byte-level small data file. 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 a new logical b...
