Abstract
One embodiment provides an eviction system for dynamically-sized caching comprising a non-blocking data structure for maintaining one or more data nodes. Each data node corresponds to a data item in a cache. Each data node comprises information relating to a corresponding data item. The eviction system further comprises an eviction module configured for removing a data node from the data structure, and determining whether the data node is a candidate for eviction based on information included in the data node. If the data node is not a candidate for eviction, the eviction module inserts the data node back into the data structure; otherwise the eviction module evicts the data node and a corresponding data item from the system and the cache, respectively. Data nodes of the data structure circulate through the eviction module until a candidate for eviction is determined.
