Abstract
Techniques perform data writing. Such techniques involve: in response to receiving a first write request, searching a cache for a target address associated with the first write request; in response to missing of the target address in the cache, determining a page usage rate in the cache; and in response to determining that the page usage rate exceeds an upper threshold, performing the first write request with a first available page in the cache. The first available page is reclaimed, independent of a refresh cycle of the cache, in response to completing the performing of the first write request.
