METHOD, APPARATUS, AND ELECTRONIC DEVICE FOR BUILDING A FILE SYSTEM IN A KEY VALUE STORAGE SYSTEM

摘要

The present invention relates to the data storage field, and in particular, to a method and an apparatus for constructing a file system in a key-value storage system, and an electronic device. According to the method for constructing a file system in a key-value storage system disclosed by the present invention, a directory number corresponding to a directory path of a directory at each level is acquired first; then, according to the directory number and a file stored in the directory at each level, corresponding keywords Key of the directory and the file are constructed. In this case, because the directory number in the keywords Key occupies relatively small space and each directory number is unique and not repeated, storage space is effectively reduced. In addition, because the directory keyword Key corresponding to the directory is constructed according to the directory number, when an operation needs to be performed on the directory, the to-be-operated directory can be directly acquired according to the directory keyword Key, which simplifies the operation procedure.
