Abstract
A method of cache management, the method comprising: identifying, among a plurality of storage items, storage items having an access count above a first threshold to generate a set of storage items; identifying, among the set of storage items, storage items having an updated access count above a second threshold to generate a subset of storage items, wherein, for each storage item, the updated access count is dependent upon a number of accesses subsequent to generating the set of storage items; and adding the storage items of the subset of storage items to a cache.
Claims20
A method comprising:
- identifying a set of storage items of a plurality of storage items having a first access count that satisfies a first threshold at a first time;
- identifying one or more storage items from the set of storage items having a second access count that satisfies a second threshold at a second time;
- and
- adding the one or more storage items to a cache.
An apparatus comprising:
- a memory;
- and
- a processing device operatively coupled to the memory, configured to:
- identify a set of storage items of a plurality of storage items having a first access count that satisfies a first threshold at a first time;
- identify one or more storage items from the set of storage items having a second access count that satisfies a second threshold at a second time;
- and
- add the one or more storage items to a cache.
A non-transitory computer readable storage medium storing instructions, which when executed, cause a processing device to:
- identify a set of storage items of a plurality of storage items having a first access count that satisfies a first threshold at a first time;
- identify one or more storage items from the set of storage items having a second access count that satisfies a second threshold at a second time;
- and
- add the one or more storage items to a cache.
