Techniques for managing data objects of a data storage system are described herein. According to one embodiment, a hash function is generated for a plurality of data objects by analyzing each of the data objects stored in the data storage system. For each of the data objects, a hash operation is performed on the data object using the hash function, generating a hash value. The hash value is associated with a predetermined attribute of the data object, such that the predetermined attribute of the data object is uniquely identified using the hash function subsequently in response to a request for accessing the predetermined attribute of the data object. The data object is then stored at a persistent storage location of the data storage system, wherein the persistent storage location is identifiable based on a hash value obtained from the hash function.
