Abstract
In one embodiment, an extent key reconstruction technique is provided for use with a set of hash tables embodying metadata. The metadata includes an extent key associated with a storage location on storage devices for write data of one or more write requests organized into an extent. Each hash table has a plurality of entries, and each entry includes a plurality of slots. A first field of the extent key is recreated implicitly from an entry in a first address space portion of a hash table. A second field of the extent key is stored in the slot. A third field of the extent key is stored in the slot. A fourth field of the extent key is recreated implicitly from the hash table of the set of hash tables.
