Horizontal and Vertical Partitioning

There are two types of database partitions: vertical and horizontal.

Vertical Partitioning

Vertical partitioning relies upon initially creating tables with fewer columns and then using additional tables to store leftover columns. Since rows are split according to their columns, vertical partitioning is also known as row splitting (opposite horizontal partitioning). As of right now, MySQL does not support vertical partitioning in its database.
