What does "LITS" mean?

LITS stands for Learned Index with Hash-enhanced Prefix Table and Sub-tries. It is a new method for organizing string data in databases. Traditional methods for indexing strings often struggle, especially when dealing with long and variable-length keys. This can make searching for information slow and complicated, particularly when there are common starting parts in the strings.

LITS aims to improve the speed and efficiency of finding string data. It uses a special table that helps break down and categorize the strings more effectively. Additionally, it includes compact structures to help perform both point and range searches quickly.

Tests have shown that LITS is significantly faster than older methods for retrieving specific pieces of string data. It not only improves point searches but also maintains good performance when scanning through larger amounts of data.
