Abstract: A wear leveling and access method and device for a non-volatile memory, and a storage medium. The method includes: logically dividing a non-volatile memory into physical units of p levels, the non-volatile memory including a plurality of physical units of the first level, each physical unit of the p−1-th level including a plurality of physical units of the p-th level, and p being a positive integer greater than one (S110); when a time period corresponding to the physical units of the q-th level arrives, replacing the data of each of the physical units of the q-th level with other physical units of the q-th level, q being any positive integer from one to p (S120).

Abstract: Provided are a metadata processing method and apparatus, and a computer-readable storage medium. In the metadata processing method, a management server obtains metadata to be processed, wherein the metadata to be processed includes a directory structure and file attributes; and according to a load condition of at least one first node for storing the file attributes and based on a rule that file attributes of a same directory are stored in a same first node, the management server stores, in the at least one first node, the file attributes of directories in the directory structure in a distributed manner.

Abstract: The disclosure provides a processing method, device and system for data of a distributed storage system. The method includes: acquiring a first schema structure of target data and a second schema structure of source data; and processing the source data into structural data of the first schema structure according to the first schema structure and the second schema structure. The disclosure solves a problem that a data schema structure in a distributed storage system in related arts is inflexible to be described. There is a beneficial effect of improving description flexibility of the data schema structure so as to improve data processing efficiency.
