MariaDB 10.8.0 Release Notes

Download 10.8.0 Release Notes Changelog Overview of 10.8

Release date: 21 Dec 2021

Do not use alpha releases in production!

MariaDB 10.8 is the current development series of MariaDB. It is an evolution of MariaDB 10.7 with several entirely new features.

MariaDB 10.8.0 is not a single release, but is instead a number of feature preview releases based on feature branches. Each should be considered as having a maturity of an Alpha release. Read more about feature preview releases here.

Thanks, and enjoy MariaDB!

Remember, these features are in separate preview packages. The subsection header text corresponds to the preview package name.

Stored Procedures INOUT Parameters

Lag free ALTER TABLE in replication

  • Normally, ALTER TABLE gets fully executed on the primary first and only then it is replicated and starts executing on replicas. With this feature ALTER TABLE gets replicated and starts executing on replicas when it starts executing on the primary, not when it finishes. This way the replication lag caused by a heavy ALTER TABLE can be completely eliminated (MDEV-11675).

Descending indexes

InnoDB redo log improvements

Auto create partition

  • For system versioned tables that are partitioned BY SYSTEM_TIME with the LIMIT or INTERVAL clause, that is, when the server automatically switches to the new history partition when the previous one becomes full, one can now use an AUTO keyword to tell the server to create more history partitions automatically as needed (MDEV-17554).
  • Note that this feature was not included in MariaDB 10.8.1.

JSON Histograms

Spider Storage Engine Improvements

  • This was mostly internal refactoring work. As a result one can now declare Spider connections using the REMOTE_SERVER, REMOTE_DATABASE, and REMOTE_TABLE attributes and not abuse the COMMENT field for that. This works both for the whole table and per partition (MDEV-5271, MDEV-27106).

Misc. features

mysqlbinlog GTID support

  • mariadb-binlog (or mysqlbinlog as it was called back when the task was created) now supports both filtering events by GTID ranges through --start-position and --stop-position, and validating a binary log's ordering of GTIDs through --gtid-strict-mode (MDEV-4989).

Windows - Improved i18n support

  • On newer versions of Windows (Windows 10 1903 or later), the mariadb client defaults to the utf8mb4 character set. Several problems with Unicode input and output in client were fixed. Command line utilities now accept all Unicode characters in user names, database names, file names etc (in the past, characters were restricted to the current ANSI codepage).

Do not use alpha releases in production!
