Techniques for managing data objects of a data storage system are described herein. According to one embodiment, a perfect hash function is generated for data objects stored in a data storage system. For each of the data objects, a hash operation is performed using the perfect hash function to indicate whether the respective data object is alive. Resources associated with the respective data object is reclaimed if it is determined that the respective data object is not alive based on a result of the hash operation using the perfect hash function, where the reclaimed resources are released back to the data storage system as free resources. Other methods and apparatuses are also described. |
