Abstract
The present application is directed towards systems and methods of hunting for a hash table entry in a hash table distributed over a multi-node system. More specifically, when entries are created in an ASDR table, the owner node of the entry may replicate the entry onto a non-owner node. The replica can act as a backup of the ASDR table entry in the event the node leaves the multi-mode system. When the node returns to the multi-node system, the node may no longer have the most up to date ASDR table entries, and may hunt to find the existence of the value associated with the entry. Responsive to receiving a request for an entry that may be outdated on the node, the node sends a request down a replication chain for an updated copy of the ASDR table entry from one of the replicas. Responsive to receiving the replica copy of the entry, the node responds to the client's request for the entry.
