Patent ID: 10127238

Abstract:
Methods and apparatus are provided for filtering dynamically loadable namespaces (DLNs). In one exemplary embodiment, a method comprises the steps of, 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 object storage of a storage system; obtaining one or more filtering directives from a user; reducing the DLN based on the one or more filtering directives to generate a filtered DLN; and dynamically loading the filtered DLN, including the metadata only for the filtered DLN, from the capacity tier of object storage into a performance tier of storage of the storage system for processing by the application. The filtered DLN is merged into the original DLN following one or more modifications to the filtered DLN.
