This guide will walk you through the different types of table partitioning supported in MySQL and demonstrate how to implement each with examples.

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. The partitioning logic divides the rows into multiple tables. The number of columns remains constant throughout partitions, while the number of rows can vary. My SQL currently supports horizontal partitioning. In this post, we’ll look at three different kinds of horizontal partitions in MySQL. When implementing range partitioning, if a column value falls within the specified range for a particular partition, the row is then added to that partition. 2. (Optional) Populate the table with sample data. In this case, download this dataset. Then, import the CSV data into a table.
