Method and system for maintaining and searching index records

One difficult problem is that a straightforward renaming of a directory containing a very large number of subdirectories and files requires locking and then updating, in parallel, the names of vast numbers of directory records. Another problem is that renaming a directory with a very large number of subdirectories and files may cause a mass migration of the metadata for the renamed objects due to their object names being changed. ...
