WhiteDB

WhiteDB is a fast and lightweight NoSQL shared memory database library written in C.

What type of database indices does WhiteDB support?

Hash Table

When working with databases and data structures a hash table can implement an associative array abstract data type that can be used to map keys to values. The hash table uses hash functions or hash code to compute an index by turning it into an array of slots, where the desired value can be found faster.

T Tree

T Tree is a type of binary tree data structure that is used by in-memory databases (also known as main-memory databases). The T tree is a balanced index tree data structure optimized for when data and indexes are both fully kept in memory.
