Abstract
A distributed cache is managed. In some embodiments, only a subset of a plurality of processing nodes may be designated as cache managers that manage the cache access history of a logical area, including having an exclusive right to control the eviction of data from cache objects of the logical area. In such embodiments, all of the processing nodes may collect cache access information, and communicate the cache access information to the cache managers. Some of the processing nodes that are not cache managers may collect cache access information from a plurality of the other non-cache managers. Each such processing node may combine this communicated cache access information with the cache access information of the processing node itself, sort the combined information per cache manager, and send the resulting sorted cache access information to the respective cache managers. The processing nodes may be arranged in a cache management hierarchy.
