Partitioning Types

Explore different partitioning types for MariaDB Server tables. Understand range, list, hash, and key partitioning to optimize data management and improve query performance.

Partitioning Types Overview

An introduction to the various partitioning strategies available in MariaDB, helping you choose the right method for your data distribution needs.

HASH Partitioning Type

Learn about HASH partitioning, which distributes data based on a user-defined expression to ensure an even spread of rows across partitions.

KEY Partitioning Type

Understand KEY partitioning, similar to HASH but using MariaDB's internal hashing function on one or more columns to distribute data.

LINEAR HASH Partitioning Type

Explore LINEAR HASH partitioning, a variation of HASH that uses a powers-of-two algorithm for faster partition management at the cost of distribution.

LINEAR KEY Partitioning Type

Learn about LINEAR KEY partitioning, which combines the internal key hashing with a linear algorithm for efficient partition handling.

LIST Partitioning Type

Understand LIST partitioning, where rows are assigned to partitions based on whether a column value matches one in a defined list of values.

RANGE COLUMNS and LIST COLUMNS Partitioning Types

Discover these variants that allow partitioning based on multiple columns and non-integer types, offering greater flexibility than standard RANGE/LIST.

RANGE Partitioning Type

The RANGE partitioning type assigns rows to partitions based on whether column values fall within contiguous, non-overlapping ranges.
