Abstract
Various embodiments of the present invention allow concurrent accesses to a cache. A request to update an object stored in a cache is received. A first data structure comprising a new value for the object is created in response to receiving the request. A cache pointer is atomically modified to point to the first data structure. A second data structure comprising an old value for the cached object is maintained until a process, which holds a pointer to the old value of the cached object, at least one of one of ends and indicates that the old value is no longer needed.
