Changes and Improvements in MariaDB 11.4

MariaDB 11.4 is a current long-term development series.


New Features

This list includes features from the short-term releases MariaDB 11.0, MariaDB 11.1, MariaDB 11.2 and the MariaDB 11.3 rolling release.



Sys Schema

  • New view sys.privileges_by_table_by_level shows granted privileges broken down by table on which they allow access and level on which they were granted. For example, if a user x has SELECT privilege granted ON db.*, this view will list all tables in the db schema with the user x having SELECT privilege on them. This is different from INFORMATION_SCHEMA.TABLE_PRIVILEGES, which only lists privileges granted on the table level (MDEV-24486)





  • Binary log writing speed was improved by moving checksum calculations out of the global binlog mutex (MDEV-31273). This is a contribution by Kristian Nielsen
  • New system variable max_binlog_total_size enables binary log purging when the total size of all binary logs exceeds the specified threshold. The implementation is based on the patch from Percona (MDEV-31404)
  • New system variable slave_connections_needed_for_purge disables binary log purging until the number of connected slaves reaches the specified threshold (MDEV-31404).
  • FULL_NODUP is a new value for the binlog_row_image system variable. It essentially works like FULL, that is all columns are included in the event, but it takes less space, because the after image omits columns that were not changed by the UPDATE statement, and have same values as in the before image. This is a contribution from Alibaba (MDEV-32589)
  • mariadb-binlog --flashback support for the FULL_NODUP mode. This is a contribution from Alibaba (MDEV-32894).
  • MariaDB can optionally maintain a special index of GTIDs and their location in the binary log. If enabled (the default), it allows finding very quickly where a new connecting replica should start replicating from. Without an index, this required scanning the binlog. This is a contribution by Kristian Nielsen (MDEV-4991).

Backup and Restore

  • New mariadb-dump option, -j, --parallel=# for increased parallelism, specifies the number of dump table jobs executed in parallel (only for use with the --tab option). Also added to mariadb-import, with --use-threads as a synonym. (MDEV-32216)
