# Partitioning Types Overview

A partitioning type determines how a partitioned table's rows are distributed across partitions. Some partition types require the user to specify a partitioning expression that determines in which partition a row are stored.

The size of individual partitions depends on the partitioning type. Read and write performance are affected by the partitioning expression. Therefore, these choices should be made carefully.

## Partitioning Types

MariaDB supports the following partitioning types:

* [RANGE](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/range-partitioning-type)
* [LIST](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/list-partitioning-type)
* [RANGE COLUMNS and LIST COLUMNS](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/range-columns-and-list-columns-partitioning-types)
* [HASH](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/hash-partitioning-type)
* [LINEAR HASH](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/linear-hash-partitioning-type)
* [KEY](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/key-partitioning-type)
* [LINEAR KEY](https://mariadb.com/docs/server/server-usage/partitioning-tables/partitioning-types/linear-key-partitioning-type)
* [SYSTEM\_TIME](https://mariadb.com/docs/server/reference/sql-structure/temporal-tables/system-versioned-tables)
