Abstract
An access request processing apparatus comprises, a processor determines an object cache page according to a write request when receiving the write request. After determining that the NVM stores a log chain of the object cache page, the processor inserts, into the log chain of the object cache page, a second data node recording information about a second log data chunk. The log chain already includes a first data node recording information about the first log data chunk. The second log data chunk is at least partial to-be-written data of the write request. Then, the processor sets, in the first data node, data that is in the first log data chunk and that overlaps the second log data chunk to invalid data.
