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

摘要

The present invention relates to the field of data storage, and more particularly to a method, an apparatus, and an electronic device for building a file system in a key value storage system. In the method for building a file system in a key value storage system disclosed by the present invention, first directory sequence numbers corresponding to directory paths of all levels of directories are acquired, and keys corresponding to directories and files are then built according to the directory sequence numbers and files stored in all levels of directories; in this case, the directory sequence numbers in the Keys occupy small space, and each directory sequence number is unique without a phenomenon of any repetition, thereby effectively saving storage space; in addition, a directory Key corresponding to a directory is built according to the directory sequence number, and when a directory needs to be operated, the directory to be operated can be directly acquired according to the Key of the directory, so that the operation process is simplified.
