MySQL Partitioning

MySQL partitioning allows tables to be subdivided into smaller, more

manageable parts, called partitions. Each partition can be processed

independently, which can enhance the performance of MySQL queries and

management tasks such as backups and restores. This can be especially

beneficial when dealing with large tables.

Partitioning is done by specifying a partition function that determines into

which partition each row will be inserted. MySQL uses the values of certain

columns (the partition key) to calculate the partition.

There are four types of partitioning available in MySQL: RANGE, LIST, HASH,

and KEY. Each type serves different use cases and has its unique

characteristics.
