Abstract
Implementations of the present specification describe evicting a memory block in a cache, including determining a temperature index value of a memory block in a cache, where the memory block is a storage unit of the cache. Based on the temperature index value of the memory block in the cache, determining a to-be-evicted memory block that needs to be cleared in the cache. A target element in the to-be-evicted memory block is migrated to a target memory block in the cache, where the target memory block is a memory block that is retained in the cache and whose available storage space is greater than storage space required by the target element. The to-be-evicted memory block is deleted from the cache.
