Abstract
Techniques for flushing metadata involve: receiving a flushing request, the flushing request instructing to flush metadata in at least one cache region to a persistent storage device; acquiring a plurality of target indicators, the target indicator at least indicating a type of a cache region and a block in the cache region, where the plurality of target indicators are classified based on types of cache regions indicated by the target indicators among the plurality of target indicators; determining, from the plurality of target indicators, at least one target indicator of the same type as the at least one cache region; and flushing metadata in a block indicated by the at least one target indicator. Such techniques avoid flushing a cache region that does not need to be flushed, shortens the response time to the flushing request, and reduces the occupancy of system resources.
