Abstract:
Methods and apparatus are provided for filtering dynamically loadable namespaces (DLNs). An exemplary method comprises, in response to a job submitted by an application, obtaining a dynamically loadable namespace (DLN) portion of a global single namespace of a file system, wherein the DLN is associated with the job and is maintained in a capacity tier of a storage system; obtaining filtering directives from a user; reducing the DLN using a filtering mechanism on a directory tree associated with the DLN, based on the filtering directives, by removing files in the directory tree of the DLN that do not satisfy requirements of the filtering directives to generate a filtered DLN; and dynamically loading the filtered DLN, including reduced metadata for the filtered DLN relative to the DLN, from the capacity tier into a performance tier of the storage system for processing by the application.
