Publication number: 20240111722Abstract: Deleting directories in a virtual distributed file system (VDFS), and non-virtual file systems, involves changing the name of a selected directory to a unique object identifier (UID) and moving the selected directory, named according to the UID, to a deletion target directory. A recursive process, implemented using a background deletion thread, starts in the current directory and identifies objects in the current directory. For an object that is a file or an empty directory, the object is added to a deletion queue. For an object that is a directory that is not empty, the recursion drops down into that directory as the new current directory. When the recursion has exhausted the selected directory, or some maximum object count has been reached, the objects identified in the deletion queue are deleted. This approach can also be used for file operations other than deletion, such as compression, encryption, and hashing.Type: ApplicationFiled: November 21, 2022Publication date: April 4, 2024Inventors: Xiaohua FAN, Zhaohui GUO, Wenguang WANG, Kiran PATIL, Abhay Kumar JAIN
