RELATIONSHIP-BASED WAN CACHING FOR OBJECT STORES

摘要

A method for pre-fetching objects from an object store and storing them in an object cache is disclosed. In one embodiment, such a method includes monitoring access to objects in an object store. The objects have metadata tags, such as user-defined or pre-defined metadata tags, associated therewith. The method further maintains a database for metadata tags associated with the objects, and keeps track of a number of object accesses per metadata tag. In the event a threshold number of object accesses for a particular metadata tag is reached, the method promotes objects having the metadata tag and/or a related metadata tag to an object cache. A corresponding system and computer program product are also disclosed.
