You are viewing an old version of this article. View the current version here.

MariaDB 10.8 is a short-term support stable series. The first stable release was in May 2022, and it will be supported until May 2023.

New Features & Improvements

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

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).
