Google B-tree

A Google B-tree is a data structure used to efficiently store, search, and organize large amounts of information across multiple storage devices. Imagine it as a well-organized filing system with multiple levels of folders: the top-level folders point to subfolders, which in turn contain more detailed files. This structure allows quick access to data by minimizing the number of steps needed to find a specific item, even when dealing with billions of records. B-trees are especially useful in databases and search engines like Google, ensuring rapid data retrieval and efficient management of enormous data sets.
