Extendible hashing visualization python. Below is the extendible hashing algorithm in Python, with the disc block / memory page association, caching and consistency issues removed. Jan 26, 2024 · There are 3 things to keep track of in an extendible hash table — a header, a directory and a bucket. A header allows you to index into a directory and a directory allows you to index into a A website to simulate how basic extendible hashing works, where you can tune the bucket size and hash function. Note a problem exists if the depth exceeds the bit size of an integer, because then doubling of the directory or splitting of a bucket won't allow entries to be rehashed to different buckets. It is an aggressively flexible method in which the hash function also experiences dynamic changes.
