Abstract:
Contentual metadata of an extended cache is stored within the extended cache. The contentual metadata of the extended cache is approximated utilizing a counting Bloom filter. The counting Bloom filter is stored within a primary cache. Contentual metadata of the primary cache is stored within the primary cache. One of a data read or a data write is executed without accessing the contentual metadata of the extended cache stored within the extended cache.
