Abstract

The present disclosure relates to a data writing method, apparatus, apparatus, and storage medium. The method includes generating a first write command for instructing a memory chip to write metadatainto a non-volatile storage medium of the memory chip, the metadata being metadata of user data of the user, according to a user-triggered write operation; Sending the first write command to the memory chip. The present disclosure improves the security of metadata and avoids frequent cache refreshes, thereby improving the I / O performance of the file system.

Description

technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a data writing method, apparatus, device, and storage medium. Background technique [0002] Generally, data in a file system is divided into user data and metadata. Among them, the user data refers to the actual data in the file, and the metadata refers to the data used to describe the user data. [0003] In the related art, a processor usually sends a write command to a memory chip for writing included data into a cache of the memory chip, and the write command may include user data and metadata of the user data. Since the metadata stores important information about the topology of the file system and the description of the file, if it is damaged, it may have a very serious impact. Therefore, in order to improve the security of metadata, after the memory chip receives a write command including metadata, it first writes the data in the write command into the cache o...
