The AVL Tree is the data structure of choice to implement cracker indices. However, it is particularly cache-inefficient for range queries, because the nodes accessed only for a few.

It works by physically self-organizing database columns into partitions, called cracked pieces. The goal is to create cracked. self organized indexing and index maintenance. • queries are used as advice to crack the database in pieces. • cracking means physically reordering the database. • sequential access for range queries is guaranteed. 2. Page 5. What is database cracking? - 2. • original column stays in insertion order. Several works have proposed different cracking techniques for different aspects including updates, tuple reconstruction, convergence, concurrency control, and robustness.
