Upgrading from MariaDB 10.7 to MariaDB 10.8

How to Upgrade

For Windows, see Upgrading MariaDB on Windows.

Before you upgrade, it would be best to take a backup of your database. This is always a good idea to do before an upgrade. We would recommend mariadb-backup.

The suggested upgrade procedure is:

  1. Modify the repository configuration, so the system's package manager installs MariaDB 10.8. For example,

  • On Debian, Ubuntu, and other similar Linux distributions, see Updating the MariaDB APT repository to a New Major Release for more information.

  • On RHEL, CentOS, Fedora, and other similar Linux distributions, see Updating the MariaDB YUM repository to a New Major Release for more information.

  • On SLES, OpenSUSE, and other similar Linux distributions, see Updating the MariaDB ZYpp repository to a New Major Release for more information.

  1. Stop MariaDB.

  2. Uninstall the old version of MariaDB.

  • On Debian, Ubuntu, and other similar Linux distributions, execute the following:sudo apt-get remove mariadb-server

  • On RHEL, CentOS, Fedora, and other similar Linux distributions, execute the following:sudo yum remove MariaDB-server

  • On SLES, OpenSUSE, and other similar Linux distributions, execute the following:sudo zypper remove MariaDB-server

  1. Install the new version of MariaDB.

  • On Debian, Ubuntu, and other similar Linux distributions, see Installing MariaDB Packages with APT for more information.

  • On RHEL, CentOS, Fedora, and other similar Linux distributions, see Installing MariaDB Packages with YUM for more information.

  • On SLES, OpenSUSE, and other similar Linux distributions, see Installing MariaDB Packages with ZYpp for more information.

  1. Make any desired changes to configuration options in option files, such as my.cnf. This includes removing any options that are no longer supported.

  2. Start MariaDB.

  3. Run mariadb-upgrade.

  • mariadb-upgrade does two things:

    1. Ensures that the system tables in the mysql database are fully compatible with the new version.

    2. Does a very quick check of all tables and marks them as compatible with the new version of MariaDB .

Incompatible Changes Between 10.7 and 10.8

On most servers upgrading from 10.7 should be painless. However, there are some things that have changed which could affect an upgrade:

Options That Have Changed Default Values

Option
Old default value
New default value

innodb_buffer_pool_chunk_size

134217728

Autosized

spider_semi_table_lock

1

0

Options That Have Been Removed or Renamed

The following options should be removed or renamed if you use them in your option files:

Option
Reason

innodb_log_write_ahead_size

On Linux and Windows, the physical block size of the underlying storage is instead detected and used.

Deprecated Options

The following options have been deprecated. They have not yet been removed, but will be in a future version, and should ideally no longer be used.

Option
Reason

keep_files_on_create

MariaDB now deletes orphan files, so this setting should never be necessary.

Major New Features To Consider

You might consider using the following major new features in MariaDB 10.8:

  • Stored procedures already have support for the IN, OUT and INOUT parameter qualifiers. Added as well for stored functions and (IN only) cursors (MDEV-10654).

  • Individual columns in the index can now be explicitly sorted in the ascending or descending order. This can be useful for optimizing certain ORDER BY cases (MDEV-13756, MDEV-26938, MDEV-26939, MDEV-26996).

  • See also System Variables Added in MariaDB 10.8.
