• A new server command, SHUTDOWN WAIT FOR ALL SLAVES, and a new mysqladmin shutdown --wait-for-all-slaves option, are added to instruct the server to wait for the last binlog event to be sent to all connected slaves before shutting down. (MDEV-18450).

Backup

• BACKUP STAGE allows one to implement very efficient backups with minimal locking. MDEV-5336.

Galera 4

In MariaDB 10.4.2 and later, Galera has been upgraded from Galera 3 to Galera 4.

Galera 4 Versions

The following table lists each version of the Galera 4 wsrep provider, and it lists which version of MariaDB each one was first released in. If you would like to install Galera 4 using yum, apt, or zypper, then the package is called galera-4.

New Features in Galera 4

The mysql database contains new tables related to Galera replication:

• wsrep_cluster

• wsrep_cluster_members

• wsrep_streaming_log

End users may read but not modify these tables.

The new streaming replication feature allows replicating transactions of unlimited size. With streaming replication, a cluster is replicating a transaction in small fragments during transaction execution. This transaction fragmenting is controlled by two new configuration variables:

• wsrep_trx_fragment_unit (bytes, rows, statements) defines the metrics for how to measure transaction size limit for fragmenting. Possible values are:

  • bytes: transaction’s binlog events buffer size in bytes

  • rows: number of rows affected by the transaction

  • statements: number of SQL statements executed in the multi-statement transaction

• wsrep_trx_fragment_size defines the limit for fragmenting. When a transaction’s size, in terms of the configured fragment unit, has grown over this limit, a new fragment will be replicated.

Transactions replicated through galera replication will now process the commit phase using MariaDB's group commit logic. This will affect transaction throughput, especially when binary logging is enabled in the cluster.

Limitations in Galera 4

Rolling Upgrades from Galera 3 to Galera 4

Rolling upgrades from MariaDB 10.3 (or earlier) to MariaDB 10.4 also require an upgrade from Galera 3 to Galera 4. Galera 4 has a lot of changes and improvements that were not present in Galera 3.

Prior to the General Availability (GA) releases of MariaDB 10.4 and Galera 4, earlier versions of MariaDB 10.4 and Galera 4 had bugs that could lead to problems if Galera 4 nodes were in a cluster with Galera 3 nodes during a rolling upgrade. In these versions, rolling upgrades were not supported. This meant that, in order to upgrade a cluster, the cluster had to be completely stopped, and the nodes could only be restarted after the entire cluster had been upgraded to MariaDB 10.4 and Galera 4.

These bugs have been fixed in more recent versions, and rolling upgrades from Galera 3 to Galera 4 are supported. In order to perform a rolling upgrade, it is recommended to upgrade to MariaDB 10.4.6 or later and Galera 26.4.2 or later. However, as a general rule, users should try to ensure that they are upgrading to the latest versions of MariaDB 10.4 and Galera 4.

For more detailed information on how to upgrade, see Upgrading from MariaDB 10.3 to MariaDB 10.4 with Galera Cluster.

General

• Crash safe Aria-based system tables (MDEV-16421)

• Added Linux abstract socket support (MDEV-15655)

• Enabled C++11 (MDEV-16410)

• Performance improvements in Unicode collations (MDEV-17534, MDEV-17511, MDEV-17502, MDEV-17474)

• User data type plugins (MDEV-4912, in progress)

• Improvements with SQL standard INTERVAL support to help functions TIMESTAMP() and ADDTIME() return more predictable results.

  • Historically, MariaDB uses the TIME data type for both "time of the day" values and "duration" values. In the first meaning the natural value range is from '00:00:00' to '23:59:59.999999', in the second meaning the range is from '-838:59:59.999999' to '+838:59:59.999999'.

  • To remove this ambiguity and for the SQL standard conformance we plan to introduce a dedicated data type INTERVAL that will be able to store values in the range at least from '-87649415:59:59.999999' to '+87649415:59:59.999999', which will be enough to represent the time difference between TIMESTAMP'0001-01-01 00:00:00' and TIMESTAMP'9999-12-31 23:59:59.999999'.

  • As a first step we support this range of values for intermediate calculations when TIME-alike string and numeric values are used in INTERVAL (i.e. duration) context, e.g. as the second argument of SQL functions TIMESTAMP(ts,interval) and ADDTIME(ts,interval), so the following can now be calculated:

SELECT ADDTIME(TIMESTAMP'0001-01-01 00:00:00', '87649415:59:59.999999');
-> '9999-12-31 23:59:59.999999'  

SELECT TIMESTAMP(DATE'0001-01-01', '87649415:59:59.999999')
-> '9999-12-31 23:59:59.999999'  

SELECT ADDTIME(TIME'-838:59:59.999999', '1677:59:59.999998');
-> '838:59:59.999999'

• Support for window UDF functions via the new method x_remove (MDEV-15073)

• Json service for plugins (MDEV-5313)

• Change in behavior for FLUSH TABLES (MDEV-5336).

• The JSON_VALID function is automatically used as a CHECK constraint for the JSON data type alias in order to ensure that a valid json document is inserted (MDEV-13916)

• MariaDB Named Commands (MDEV-17591)

• MariaDB systemd multi-instance service have changed. See systemd page for details.

Notable Items

SSL

• The server no longer tolerates incorrectly configured SSL (MDEV-29811). If you have enabled SSL in my.cnf but have not configured it properly (for example, a certificate file is missing), MariaDB used to silently disable SSL, leaving you under impression that everything was fine and connections were secure. Since this release, MariaDB will fail to start if SSL is enabled, but cannot be switched on.

Backup

• mariadb-backup --compress hangs (MDEV-29043)

• Assertion on info.page_size failed in xb_delta_open_matching_space (MDEV-18589)

InnoDB

• InnoDB unnecessarily extends data files (MDEV-13013)

• MVCC and locking MDEV-29666, MDEV-27927

• Virtual columns MDEV-29299, MDEV-29753

Galera

• Galera updated to 26.4.13

• Galera server crashes after 10.3 > 10.4 upgrade (MDEV-29375)

• wsrep_incoming_addresses status variable prints 0 as port number if the port is not mentioned in wsrep_node_incoming_address system variable (MDEV-28868)

JSON

• JSON_VALUE() does not parse NULL properties properly (MDEV-27151)

Replication

• minor correction in unsafe warning message (MDEV-28827)

• False replication error-stop of REVOKE PRIVILEGES from a non-existing user on primary (MDEV-28530) in combination with a filtering replica is corrected

• SET DEFAULT ROLE replication is mended on a replica that filters system tables (MDEV-28294)

Repositories

• Beginning with the next release (Q1 2023), our Yum, DNF, and Zypper repositories for Red Hat, Fedora, and SUSE will be migrated to being signed with a new GPG key. The key we are migrating to is the same one we already use for our Debian and Ubuntu Repositories.

  • The short Key ID is: 0xC74CD1D8

  • The long Key ID is: 0xF1656F24C74CD1D8

  • The full fingerprint of the key is: 177F 4010 FE56 CA33 3630 0305 F165 6F24 C74C D1D8

  • The key can be imported now in preparation for this change using the following command:

sudo rpm --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEY

Docker Official Image

The following changes have been made to the docker.io/library/mariadb container image.

• The number of gpg packages packages has been removed, leaving enough to apt-get update, but dirmngr that would fetch keys has been removed. (inspired by issue #469)

• The environment variable LANG=C.UTF-8 has been added for those that exec into containers and copy paste UTF8 characters (fixes issue #468).

• Adds OCI labels to image (fixes issue 436 and users need for version)

• MariaDB config: skip-host-cache and skip-name-resolve moved to /etc/mysql/mariadb.conf.d/05-skipcache.cnf

Security

• Fixes for the following security vulnerabilities: <</style
