Upgrading from MariaDB 10.7 to MariaDB 10.8
Contents
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 Mariabackup.
The suggested upgrade procedure is:
- 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.
- Stop MariaDB.
- 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
- On Debian, Ubuntu, and other similar Linux distributions, execute the following:
- 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.
- Make any desired changes to configuration options in option files, such as
my.cnf. This includes removing any options that are no longer supported. - Start MariaDB.
- Run mariadb-upgrade.
mariadb-upgradedoes two things:- Ensures that the system tables in the mysql database are fully compatible with the new version.
- 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).
