Abstract
Embodiments of the present disclosure provide a computer-implemented method and an apparatus for a storage system. The method comprises: in response to receiving a read request of a first container for data in a storage device, obtaining an identifier associated with the read request; searching for metadata of the read request in a metadata set based on the identifier, the metadata recording addressing information of the read request, the metadata set including metadata of access requests for the storage device during a past period; and in response to finding the metadata of the read request in the metadata set, determining, based on the metadata, a cached page of a second container storing the data; and providing the cached page from the second container to the first container to avoid reading the data from the storage device.
