Extendible hashing is a type of hash system which treats a hashcode as a bit string, and uses a trie for bucket lookup. Because of the heirarchical nature of the system, re-hashing is an incremental operation (done one bucket at a time, as needed). This means that time sensitive applications are less affected by table growth than by standard full-table rehashes.
