Abstract

See full text

A method, computer program product, and system for partitioning keys for a hash table in order to improve performance of the hash table. A hash function is used to generate a hash table by mapping a set of keys to a corresponding set of hash codes, and a hash failure is detected if the hash function fails to map the entire set of keys. To resolve the hash failure, the set of keys is partitioned to form subsets of keys that can be individually mapped.
