Abstract
Embodiments are provided for deferring allocation of storage for segments. The method includes receiving, at a first moment in time, a request to allocate a first segment within a memory. Information corresponding to the first segment is stored in a first entry in a hash table, and memory is allocated for the first segment. Information about the first segment is returned to an entity that requested the allocation of the first segment, where the first segment is not allocated auxiliary storage until predefined criteria are satisfied. At a second moment in time, upon receiving an indication to deallocate the first segment, memory corresponding to the first segment is deallocated, where the first segment is never allocated auxiliary storage and the first entry in the hash table is deleted.
