• Windows binaries now use high-precision timer when available (MDEV-15694). This makes much less probable for two queries to have the same CURRENT_TIMESTAMP(6) value, for example.

• Two new ALTER TABLE ... ALGORITHM options, INSTANT and NOCOPY, which allow operations that would require any data files to be modified, or that would require rebuilding the clustered index respectively, to be refused rather than potentially perform slowly (MDEV-13134)

Compatibility

• On Linux, shrink the core dumps by omitting the InnoDB buffer pool (MDEV-10814)

Encryption

• Temporary files created by merge sort and row log are encrypted if innodb_encrypt_log is set to 1, regardless of whether the table encrypted or not (MDEV-12634).

Optimizer/Performance

• Condition pushdown through PARTITION BY clause of window functions (MDEV-10855)

• Performance improvements to persistent data structures: MDEV-15090, MDEV-15132

Storage Engines

InnoDB

• innodb_fast_shutdown now has a new mode, 3, which skips the rollback of connected transactions (MDEV-15832)

Spider

The Spider storage engine has been updated to 3.3.13. The partitioning storage engine has been updated to support all the new Spider features including:

• Direct join support. This allows Spider to do JOINS and GROUP BYs internally.

• Direct update and delete.

• Direct aggregates.

• slave_transaction_retry_errors and slave-transaction-retry-interval allow more control over handling delays or conflicts when applying binary logs.

Most of the features were done as part of MDEV-7698.

OQGRAPH

• OQGraph now supports the "leaves" algorithm (MDEV-11271) — contribution by Heinz Wiesinger

Partition Engine

• The Information Schema Columns table now displays system versioning info in the EXTRA column - MDEV-15062

Logging

• Disable logging of certain statements to the general log or the slow query log with the log_disabled_statements and log_slow_disabled_statements system variables.

• A new option to log_slow_filter, filsort_priority_queue.

Replication

• Per-engine mysql.gtid_slave_pos tables (MDEV-12179) — Implemented by Kristian Nielsen funded by Booking.com.

Data Type API

10.3 continues refactoring for the data type API started in 10.2, which will make it possible to have user data type plugins. This work is still in progress (see MDEV-4912 for the current status and subtasks). Most of the task in this category do not change the server behavior. Some tasks do have a visible effect.

Idle Transactions

Connections with idle transactions can be automatically killed after a specified time period by means of the idle_transaction_timeout, idle_readonly_transaction_timeout and idle_write_transaction_timeout system variables.

System Variables

For a list of all new variables, see System Variables Added in MariaDB 10.3 and Status Variables Added in MariaDB 10.3.

• New system variable gtid_pos_auto_engines.

• New system variable secure_timestamp for restricting the direct setting of a session timestamp (MDEV-15923)

• Added bind_address as a system variable (MDEV-12542).

• The max value of the max_prepared_stmt_count system variable has been increased from 1048576 to 4294967295

• The proxy_protocol_networks variable can now be modified without restarting the server (MDEV-15501)

Notable Items

SSL

• The server no longer tolerates incorrectly configured SSL (MDEV-29811). If you have enabled SSL in my.cnf but have not configured it properly (for example, a certificate file is missing), MariaDB used to silently disable SSL, leaving you under impression that everything was fine and connections were secure. Since this release, MariaDB will fail to start if SSL is enabled, but cannot be switched on.

Backup

• mariadb-backup --compress hangs (MDEV-29043)

InnoDB

• InnoDB unnecessarily extends data files (MDEV-13013)

• Adaptive hash index MDEV-27700, MDEV-29384

• MVCC and locking MDEV-29666, MDEV-27927

• Virtual columns MDEV-29299, MDEV-29753

JSON

• JSON_VALUE() does not parse NULL properties properly (MDEV-27151)

Replication

• minor correction in unsafe warning message (MDEV-28827)

• False replication error-stop of REVOKE PRIVILEGES from a non-existing user on primary (MDEV-28530) in combination with a filtering replica is corrected

• SET DEFAULT ROLE replication is mended on a replica that filters system tables (MDEV-28294)

Repositories

• Beginning with the next release (Q1 2023), our Yum, DNF, and Zypper repositories for Red Hat, Fedora, and SUSE will be migrated to being signed with a new GPG key. The key we are migrating to is the same one we already use for our Debian and Ubuntu Repositories.

  • The short Key ID is: 0xC74CD1D8

  • The long Key ID is: 0xF1656F24C74CD1D8

  • The full fingerprint of the key is: 177F 4010 FE56 CA33 3630 0305 F165 6F24 C74C D1D8

  • The key can be imported now in preparation for this change using the following command:

sudo rpm --import https://supplychain.mariadb.com/MariaDB-Server-GPG-KEY

Docker Official Image

The following changes have been made to the docker.io/library/mariadb container image.

• The number of gpg packages has been removed, leaving enough to apt-get update, but dirmngr that would fetch keys has been removed. (inspired by issue #469)

• The environment variable LANG=C.UTF-8 has been added for those that exec into containers and copy paste UTF8 characters (fixes issue #468).

• Adds OCI labels to image (fixes issue 436 and users need for version)

• MariaDB config: skip-host-cache and skip-name-resolve moved to /etc/mysql/mariadb.conf.d/05-skipcache.cnf

Security

• Fixes for the following security vulnerabilities:

When upgrading from MariaDB 10.3.8 or earlier to MariaDB 10.3.9 or higher, running mysql_upgrade is required due to changes introduced inMDEV-14637.
