ABSTRACT:
A method and apparatus for obtaining data of a cache node in a tree-structured cluster is described. In one embodiment, a query for data in the cache node of the tree-structured cluster is received. A determination of whether the data is stored in the queried cache node is made. An inquiry of other cache nodes in the cluster for the data is performed. An instance of the data from a cache node storing the data is replicated to the cache node receiving the query.
