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.
SSL/TLS
Note that this feature did not make it into MariaDB 11.3, but is in MariaDB 11.4.
SSL is now enabled in the server by default. No configuration necessary, if no server certificate was provided a self-signed certificate will be automatically generated by the server. See Mission Impossible: Zero-Configuration SSL on mariadb.org (MDEV-31856).
Clients now can validate self-signed server certificates if the mysql_native_password or ed25519 authentication is used and account password is not empty (MDEV-31855).
Clients now require SSL and have --ssl-verify-server-cert enabled by default (MDEV-31857).
Replication clients do that too, MASTER_SSL_VERIFY_SERVER_CERT is enabled by default.
Use
--disable-ssl
or--disable-ssl-verify-server-cert
to revert to the old behavior.Clients can use new command line options --tls-fp and --tls-fplist to verify the server certificate by its fingerprint
Data Types
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 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)
Application-Time Periods
Note that this feature did not make it into MariaDB 11.3, but is in MariaDB 11.4.
Add views for periods in information_schema (MDEV-22597), in particular
New view INFORMATION_SCHEMA.PERIODS
New view INFORMATION_SCHEMA.KEY_PERIOD_USAGE
New columns
IS_SYSTEM_TIME_PERIOD_START
andIS_SYSTEM_TIME_PERIOD_END
in the INFORMATION_SCHEMA.COLUMNS view
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):
debug (deprecated since MariaDB 5.5.37)
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)
