Abstract
A method and system for reinserting a chain into a hash table of a computer system are described. The chain includes a plurality of keys. The hash table includes a key fields and link fields associated with the key fields. The hash table utilizes an initial collision resolution scheme that precludes coalescing of chains. The method and system include providing a binary tree including nodes corresponding to the keys of the chain. The nodes include a root node corresponding to a root key and at least one child node corresponding to at least one child key. The method and system also include storing a pair of child keys in two empty adjacent key fields and storing a first empty adjacent key value of one of the two empty adjacent key fields in the home link field if the root node is the parent node of more than one child node.
