Column indexes
This is the most common way to define an index where only a single column is involved. MySQL 8 stores a copy of column values in a data structure so that rows can be accessed quickly. MySQL 8 uses a B-Tree data structure to enable values to be accessed quickly. The B-Tree execution will work based on operators, such as =, <, >, BETWEEN, IN, and many more, which were defined in the where condition. You can get details on the B-Tree data structure and its execution in the next topic. We will discuss the characters of column indexes in the coming sections.
