B-tree 是一种加速查找的数据结构,从主键索引或二级索引里查找一个记录(tuple)需要进行B-tree 遍历。通过 btr_cur_search_to_nth_level 这个函数完成 voidbtr_cur_search_to_nth_level(dict_index_t*index,/*!< in: index */ulintlevel,/*!< in: the tree level of search */constdtuple_t*tuple,/...

Incomputer science, aB-treeis a self-balancing tree data structure that maintains sorted data and allows the following operations in logarithmic time. searches, sequential access, insertions, deletions The B-tree generalizes thebinary search tree...
B-tree Data Structure >> The Road to Membership and Baeldung Pro. Going into ads,no-ads reading, and bit about how Baeldung works if you're curious :) 1. Overview In this tutorial, we’ll discuss a self-balancing tree data structure: B-tree.We’ll present the properties and various ...

B - Tree Datastructure In search trees like binary search tree, AVL Tree, Red-Black tree, etc., every node contains only one value (key) and a maximum of two children. But there is a special type of search tree called B-Tree in which a node contains more than one value (key) and...
