Abstract
A technique for storing data in a data storage system detects that a read is being performed pursuant to a data copy request. In response, the data storage system stores a digest of the data being read in an entry of a digest cache. Later, when a write pursuant to the same copy request arrives, the storage system obtains the entry from the digest cache and completes the write request without creating a duplicate copy of the data.
