Abstract
Techniques manage metadata. Such techniques involve: in response to receiving a request for accessing metadata in a first page, determining, from a plurality of storage units including pages for storing metadata, a storage unit where the first page is located, the plurality of storage units including a first storage unit and a second storage unit, an access speed of the second storage unit exceeding an access speed of the first storage unit; accessing, from the determined storage unit, the first page for metadata; in response to the first page being accessed from the first storage unit, determining whether hotness of the first page exceeds a threshold level; and in response to the hotness of the first page exceeding the threshold level, transferring the first page from the first storage unit to the second storage unit. Accordingly, such techniques can improve the efficiency for accessing the metadata.
