MariaDB 11.3 Changes & Improvements

MariaDB 11.3 is an old rolling release and is no longer maintained. Please use a more recent release.

The most recent release of MariaDB 11.3 is:MariaDB 11.3.2 Stable (GA) Download Now

MariaDB 11.3 is a previous rolling release. It is the first release in the new release model. From 11.3, we stop doing GA bug fix releases within each minor version. See Adjusting the MariaDB Server release model (mariadb.org).

Upgrading

  • See Upgrading Between Major MariaDB Versions and Upgrading from MariaDB 11.2 to MariaDB 11.3.

New Features & Improvements

Connection Redirection

  • Added a redirect mechanism using the redirect_url system variable (MDEV-15935)

  • At the moment client-side support is missing

InnoDB

  • Shrink temporary tablespaces without restart by setting the innodb_truncate_temporary_tablespace_now system variable. (MDEV-28699)

Replication

  • Add keywords "SQL_BEFORE_GTIDS" and "SQL_AFTER_GTIDS" for START SLAVE UNTIL (MDEV-27247). SQL_BEFORE_GTIDS stops the replica when it sees gtids of the option's argument list, without executing them.

Data Types

  • It is now possible to create partitions on tables that contain GEOMETRY types (MDEV-19177)

  • INET4 data types can now be cast into INET6 types (MDEV-31626)

  • This means INET4 values can be compared with INET6 values and can be inserted into INET6 columns; the server can automatically convert INET4 value into INET6 as needed.

Functions

  • Values generated by the Key Derivation Function KDF are resistant against password hashing generators, so are good for strongly hashed passwords (MDEV-31474).

Date and Time

  • DATE_FORMAT function can now print the current time zone abbreviation and current time zone offset from UTC with %Z and %z format specifiers. (MDEV-31684)

Optimizer

  • Queries like UCASE(varchar_col)=... can now use an index on varchar_col if its collation is case insensitive. An optimizer_switch option, sargable_casefold=ON, has been added to enable this optimization. (MDEV-31496)

Privileges

  • Add a new database-level privilege, SHOW CREATE ROUTINE that allows one to see the routine definition even if the user isn't the routine owner (MDEV-29167)

Processlist

  • Added a SENT_ROWS column to the Information Schema PROCESSLIST table, as well as extended the display size for the columns in processlist to ensure that most results will fit in display (MDEV-3953)

OLD_MODE

  • Setting a non-default old_mode value will now always issue a deprecation warning (MDEV-31811)

mariadb-backup

  • mariadb-backup --innobackupex mode has been deprecated (MDEV-31505)

Spider

  • The Spider storage engine now supports table options instead of having to encode them in COMMENT/CONNECTION strings. When any table option is specified, Spider will ignore COMMENT/CONNECTION strings at the same table/partition/subpartition. A new variable spider_ignore_comments is introduced to ignore them globally at all levels (table/partition/subpartition). Another variable, spider_suppress_comment_ignored_warning, is introduced to suppress warnings when Spider ignores COMMENT/CONNECTION strings. (MDEV-28856)

Removed

The following deprecated features and system variables have been removed (MDEV-32104):

  • sr_YU locale (deprecated since MariaDB 10.0.11)

  • "engine_condition_pushdown" in optimizer_switch (deprecated since MariaDB 10.1.1)

  • date_format, datetime_format, time_format, max_tmp_tables (deprecated since MariaDB 10.1.2)

  • wsrep_causal_reads (deprecated since MariaDB 10.1.3)

  • "parser" in mroonga table comment (deprecated since MariaDB 10.2.11)

Variables

  • For a list of all new variables, see System Variables Added in MariaDB 11.3.
