MariaDB 10.5 is no longer maintained. Please use a more recent release.

MariaDB 10.5 is a previous major release series. The first stable release was in June 2020, and it was maintained until June 2025.

Upgrading

• See Upgrading Between Major MariaDB Versions and Upgrading from MariaDB 10.4 to MariaDB 10.5.

Implemented Features

See the Differences in MariaDB Enterprise Server 10.5 page for items that are different between MariaDB Community Server 10.5 and MariaDB Enterprise Server 10.5.

ColumnStore

• This release of MariaDB Server includes the MariaDB ColumnStore storage engine. Note, that plugins have independent maturity levels and MariaDB ColumnStore in 10.5.4 has Beta maturity.

Binaries Named mariadb (mysql Symlinked)

• All binaries previously beginning with mysql now begin with mariadb, with symlinks for the corresponding mysql command. (MDEV-21303)

• When starting the MariaDB server via the systemd service it will be started using the mariadbd binary name, so this will now show up in the system process list instead of mysqld

• Same for the mariadbd-safe wrapper script. Even when called via the mysqld_safe symlink, it will start the actual server process as mariadbd, not mysqld now. This also affects startup via system service init scripts on platforms that don't yet have switched to SystemD

INET 6 Data Type

• New INET6 data type for storing IPv6 addresses (MDEV-274)

Amazon S3

• The S3 storage engine allows one to archive MariaDB tables in Amazon S3, or any third-party public or private cloud that implements S3 API ( MDEV-22606)

• Both S3 tables and partitioned S3 tables are discoverable. This means that if you create a partitioned S3 table, both the partitioned table and its partitions can be directly used by another server that has access to the S3 storage. (MDEV-22088)

Privileges Made More Granular

• Split SUPER privilege to smaller privileges (MDEV-21743). New privileges were added so that more fine grained tuning of what each user can do can be applied:

  • BINLOG ADMIN

  • BINLOG REPLAY

  • CONNECTION ADMIN

  • FEDERATED ADMIN

  • READ_ONLY ADMIN

  • REPLICATION MASTER ADMIN

  • REPLICATION SLAVE ADMIN

  • SET USER

• The REPLICATION CLIENT privilege was renamed to BINLOG MONITOR. The old syntax is understood for compatibility (MDEV-21743).

• The SHOW MASTER STATUS statement was renamed to SHOW BINLOG STATUS (MDEV-21743). The old syntax is understood for compatibility.

• A number of statements changed the privileges that they require. The old privileges were historically inappropriately chosen in the upstream. 10.5.2 fixes this problem. Note, these changes are incompatible to previous versions. A number of GRANT commands might be needed after upgrade.

  • SHOW BINLOG EVENTS now requires the BINLOG MONITOR privilege (required REPLICATION SLAVE prior to 10.5.2).

  • SHOW SLAVE HOSTS now requires the REPLICATION MASTER ADMIN privilege (required REPLICATION SLAVE prior to 10.5.2).

  • SHOW SLAVE STATUS now requires the REPLICATION SLAVE ADMIN or the SUPER privilege (required REPLICATION CLIENT or SUPER prior to 10.5.2).

  • SHOW RELAYLOG EVENTS now requires the REPLICATION SLAVE ADMIN privilege (required REPLICATION SLAVE prior to 10.5.2).

• In order to help the server understand which version a privilege record was written by, the mysql.global_priv.priv field contains a new JSON field, version_id (MDEV-21704)

• SHOW PRIVILEGES now correctly lists the Delete history privilege, rather than displaying it as Delete versioning rows. (MDEV-20382)

InnoDB: Performance Improvements etc.

• Extend SHOW STATUS LIKE 'Innodb_%' (MDEV-18582)

• Clean up INFORMATION_SCHEMA.INNODB_ tables (MDEV-19940)

• Doublewrite buffer is unnecessarily used for newly (re)initialized pages (MDEV-19738)

• Defer change buffer merge until pages are requested (MDEV-19514)

• Remove dummy tablespace for the redo log (MDEV-18115)

• Optimize access to InnoDB page header fields (MDEV-21133)

• Remove multiple InnoDB buffer pool instances (MDEV-15058)

  • Columns that indicated the buffer pool instance from the Information Schema innodb_buffer_page, innodb_buffer_page_lru, innodb_buffer_pool_stats, innodb_cmpmem and innodb_cmpmem_reset tables now return a dummy value of 0.

• Remove buf_page_t::newest_modification (MDEV-21132)

• Replace recv_sys_t::addr_hash with a std::map (MDEV-19586)

• Obsolete internal parser for FK in InnoDB (MDEV-20480)

• InnoDB thread pool for background tasks (MDEV-16264)

• An upgrade will only be possible after a clean shutdown. mariadb-backup --prepare will not work with backups taken before version 10.5.2.

• Efficient InnoDB redo log record format (MDEV-12353)

• Improve InnoDB redo log group commit performance (MDEV-21534)

• Do not acquire InnoDB record locks when covering table locks exist (MDEV-14479)

• Issue a message on changing deprecated innodb_log_files_in_group (MDEV-21990)

• Optimize append only files for NVDIMM (MDEV-17084)

• Avoid writing freed InnoDB pages (MDEV-15528)

InnoDB New Defaults for Variables

• innodb_adaptive_hash_index now defaults to OFF (MDEV-20487)

• innodb_checksum_algorithm now defaults to full_crc32 (MDEV-19534)

InnoDB Removed or Deprecated Variables

• innodb_buffer_pool_instances

• innodb_checksums (MDEV-19534)

• innodb_locks_unsafe_for_binlog (MDEV-19544)

• innodb_log_checksums (MDEV-19543)

• innodb_log_files_in_group (MDEV-14425 & MDEV-20907)

• innodb_log_optimize_ddl (MDEV-19747)

• innodb_rollback_segments (MDEV-19570)

• innodb_scrub_log and innodb_scrub_log_speed (MDEV-21870)

• Remove INFORMATION_SCHEMA.INNODB_TABLESPACES_SCRUBBING table and deprecate and ignore:

• innodb-background-scrub-data-uncompressed

• innodb-background-scrub-data-compressed

• innodb-background-scrub-data-interval

• innodb-background-scrub-data-check-interval (MDEV-15528)

• innodb_stats_sample_pages (MDEV-19551)

• innodb_undo_logs (MDEV-19570)

• innodb_thread_concurrency

• innodb_commit_concurrency

• innodb_replication_delay

• innodb_concurrency_tickets

• innodb_thread_sleep_delay

• innodb_adaptive_max_sleep_delay (MDEV-23379)

Performance Schema Updates to Match MySQL 5.7 Instrumentation and Tables

• Memory (MDEV-16431)

• Meta data locking (MDL) (MDEV-16432)

• Prepared statements (ps) (MDEV-16433)

• [show] status instrumentation and tables (MDEV-16438)

• Stored procedures (MDEV-16434)

• Sxlocks (MDEV-16436)

• Transactions (MDEV-16435)

• User variables (MDEV-16439)

Galera: Full GTID Support

• Add full GTID support to Galera cluster (commit). With this feature all nodes in a cluster will have the same GTID for replicated events originating from the cluster. Also added a new variable, wsrep_gtid_seq_no, to manually update the WSREP GTID sequence number in the cluster (similar to how the gtid_seq_no variable is used for non-WSREP transactions).

• Add new mode to wsrep_OSU_method in which Galera checks storage engine of the affected table (MDEV-20051)

• Galera: Replicate MariaDB GTID to other nodes in the cluster (MDEV-20720)

Binary Log and Replication: More Metadata

• slave_parallel_mode now defaults to optimistic (MDEV-18648).

• Make REPLICA a synonym for SLAVE in SQL statements (MDEV-20601)

• ENFORCE option for slave_run_triggers_for_rbr (MDEV-21833)

• Extended binlog metadata (MDEV-20477) to include new fields. This was done to solve replication issues when the Master and Slave table had different definitions for a column which could lead to data loss (MDEV-19708). It also enables us to do better replication with pluggable data types in the future.

  • The new metadata fields are:

    • Signedness of Numeric Columns

    • Character Set of Character Columns and Binary Columns

    • Column Name

    • String Value of SET Columns

    • String Value of ENUM Columns

    • Primary Key

    • Character Set of SET Columns and ENUM Columns

    • Geometry Type

  • Also added a new global variable, binlog_row_metadata to control the amount of metadata logged. Possible values are:

    • FULL - all metadata is logged

    • MINIMAL - only metadata required by a worker is logged

    • NO_LOG - No metadata is logged (default)

• Binary log DDL entries can now be marked that they should be ignored if the target table doesn't exist (implicit IF EXISTS).

• mariadb-binlog output is extended to show all replication flags. Example of output: SET @@session.foreign_key_checks=1, @@session.sql_auto_is_null=0, @@session.unique_checks=1, @@session.autocommit=1, @@session.check_constraint_checks=1, @@session.sql_if_exists=0/*!*/.

• SHOW BINLOG EVENTS and SHOW RELAYLOG EVENTS are extended to show replication flags.

Syntax

• INSERT ... RETURNING (MDEV-10014) - returns SELECT of inserted rows (analogous to DELETE ... RETURNING)

• REPLACE ... RETURNING (MDEV-10014)

• EXCEPT ALL and INTERSECT ALL (MDEV-18844)

• Application period tables: WITHOUT OVERLAPS (MDEV-16978)

• Setup default partitions for system versioning (MDEV-19903)

• Database comments in CREATE DATABASE and ALTER DATABASE statements (MDEV-307)

• ALTER TABLE ... RENAME INDEX / KEY (MDEV-7318)

• ALTER TABLE ... RENAME COLUMN (MDEV-16290)

• ALTER TABLE and RENAME TABLE now support IF EXISTS.

• Add VISIBLE attribute for indexes in CREATE TABLE (MDEV-22199)

• Recursive CTE cycle detection using CYCLE clause (MDEV-20632)

• RELEASE_ALL_LOCKS hold by GET_LOCK() (MDEV-10569)

• Fix REFERENCES constraint in column definition (MDEV-20729)

JSON

• Added JSON_ARRAYAGG. This returns a JSON array containing an element for each value in a given set of JSON or SQL values. It acts on a column or an expression that evaluates to a single value.

• Added JSON_OBJECTAGG. This returns a JSON object containing key-value pairs. It takes two expressions that evaluate to a single value, or two column names, as arguments, the first used as a key, and the second as a value.

Thread Pool

• Information Schema tables (THREAD_POOL_GROUPS, THREAD_POOL_QUEUES, THREAD_POOL_STATS and THREAD_POOL_WAITS) for internals of generic thread_pool (MDEV-19313).

Performance Improvements

• Speed up binary row logging code

• Range optimizer speedups. Removed double calls to records_in_range() for some cases.

• Costs for using MEMORY tables updated to be more accurate

• Fixed that 'ref' access is preferred over 'range' for the same index.

• Improve connect speed (up to 25%). (MDEV-19515)

Query Optimizer

• Improve Protocol performance for numeric data by avoiding unnecessary character string conversions (MDEV-23162, MDEV-23478)

• ANALYZE for statements is improved, now it also shows the time spent checking the WHERE clause and doing other auxiliary operations (MDEV-20854)

• Inferred IS NOT NULL predicates can be used by the range optimizer (MDEV-15777)

• Allow packed sort keys and values of non-sorted fields in the sort buffer (MDEV-21263 & MDEV-21580)

  • Makes filesort temporary files much smaller when VARCHAR, CHAR or BLOBs are used!

General

• The Information Schema SYSTEM_VARIABLES Table has a new column showing from which config file a variable derives its value (MDEV-12684)

• Switch Perl DBI scripts from DBD::mysql to DBD::MariaDB driver (MDEV-19755)

• The Aria max key length is now 2000 bytes, compared to 1000 bytes in MyISAM.

• DROP TABLE now reliably deletes table remnants inside a storage engine even if the .frm file is missing (MDEV-11412)

• Accelerated crc32() function for AMD64, ARMv8, POWER 8 (MDEV-22669)

• Binary tarball size has been reduced (MDEV-21943)

PCRE (Perl Compatible Regular Expressions)

• Migrate to PCRE2 (MDEV-14024), a newer version of the pcre library.

Variables

• For a list of all new variables, see System Variables Added in MariaDB 10.5 and Status Variables Added in MariaDB 10.5.

• The Information Schema SYSTEM_VARIABLES Table has a new column showing from which config file a variable derives its value (MDEV-12684).

• Port show_old_temporals from MySQL 5.6 (MDEV-19906). If set, old temporal data types (created with a pre-10.0 version of MariaDB) are displayed with a /* mariadb-5.3 */ comment.

• Numerous deprecated variables removed (MDEV-18650)

  • multi_range_count

  • thread_concurrency

  • timed_mutexes

Notable Items

Storage Engines

InnoDB

• Incorrect undo logging for indexes on virtual columns whose index ID does not fit in 32 bits (MDEV-36613)

Spider

• The untested ha_spider::index_first_internal constructs broken queries (MDEV-36324)

• Unexpected error 1264 'Out of Range Value for Column' when inserting into ... select ... from a spider table (MDEV-35874)

• Tests calling the udf spider_copy_tables fail with --view-protocol (MDEV-36335)

Data Definition - Alter Table

• ALTER TABLE…SEQUENCE does not work correctly with InnoDB (MDEV-36038)

GIS

• Server aborts while deleting the record in spatial index (MDEV-35420)

Upgrades

• Upgrades fail on Windows (MDEV-36128)

OTHER

• Field pointer may be uninitialized in fill_record (MDEV-36181)

• Wrong results from tables with a single record and an aggregate (MDEV-35238)

Galera

• Galera updated to 26.4.22

• With wsrep_ignore_apply_errors = 0, the node crashes due to assertion thd->is_error() failed in Sql_cmd_dml::prepare(), shown in the logs (MDEV-35946)

• In some cases, if there are MDL locks (for example, when LOCK TABLE is executed), a node could get stuck in the system thread due to incorrect handling of metadata locks (MDL) in server code when a transaction was BF aborted. (MDEV-35941)

• Regression after the fix for MDEV-31413 - sometimes the server crashes with an assertion in wsrep::transaction::before_rollback(), for example when using OPTIMIZE TABLE on an ARIA table with wsrep_osu_method=RSU. (MDEV-32631)

• In Galera, creating sequence with a small cache leads to signal 6 error: [ERROR] WSREP: FSM: no such a transition REPLICATING -> COMMITTED. (MDEV-33850)

• Assertion `commit_trx' failed in innobase_commit() (ha_innodb.cc). An INSERT with sql_log_bin=0 is still replicated in Galera (per MDEV-7205), despite binary logging being disabled. This results in a partial binlog bypass, requiring a two-phase commit (2PC). During 2PC, the INSERT is first prepared (entering the PREPARED state in InnoDB), and on commit, the new assertion from MDEV-24035 fails, causing a crash with "Assertion 'commit_trx' failed" in logs. (MDEV-35658)

• When a sequence is used and inserts run in parallel on multiple Galera nodes, a transaction may be aborted after passing certification. If it then attempts to roll back, the binlog statement cache—which includes reserved sequence values—may be written prematurely. This causes a crash with the diagnostic "WSREP: FSM: no such a transition REPLICATING -> COMMITTED" in the logs, as the transaction is supposed to replay and only write to the binlog during the final commit. (MDEV-33589)

• After a corrupted table on one node triggers the cluster to vote to evict a node that failed a transaction, the current master can't commit any more and hangs. To avoid this crash in the future, the user should also update the galera library to version 26.4.21+. (MDEV-34998)

• Creating partitioned tables is disallowed when wsrep_osu_method=TOI and wsrep_strict_ddl=ON, preventing alteration or deletion of partitioned tables. (MDEV-27861)

• Attempting to create a CONNECT engine table results in "non-InnoDB sequences in Galera cluster" error message in logs due to an incorrect engine check. (MDEV-35748)

• Build fails with cmake 4.0.0 due to wsrep (MDEV-36422)

Partitioning

• corruption when query cache cannot allocate block (MDEV-34075)

Data Manipulation - Update

• Stack looping and SIGSEGV in Item_args::walk_args on UPDATE (MDEV-31647)

Server

• Server crash in find_field_in_tables, Assertion `name' failed in find_field_in_table_ref (MDEV-25012)

• Server crash when inserting from derived table containing insert target table (MDEV-32086)

• MariaDB effectively running as root CAP_DAC_OVERRIDE (MDEV-36229)

• Build fails with cmake 4.0 (MDEV-36506)

Plugin - Audit

• Long server_audit_file_path causes buffer overflow (MDEV-36245)

Optimizer

• group by handler missing constant fields when selecting from a view (MDEV-36307)

Security

• Fixes for the following security vulnerabilities:

  • CVE-2025-30722

  • CVE-2025-30693

  • CVE-2023-52970

  • CVE-2023-52969

Notable Items

Storage Engines

InnoDB

• Fix assertion failure on cascading foreign key update of table with vcol index in parent (MDEV-29182)

• Fix issue where ON UPDATE SET NULL could not be specified on a NOT NULL column (MDEV-35445)

Memory

• Fix possible crash on DELETE from a HEAP table (MDEV-22695)

Spider

• Fix possible Spider thread hang in 'Update' state on 2nd INSERT (MDEV-35064)

Replication

• Fix incorrect formatting of timestamp during mariadb-binlog parsing of a binary log, causing point in time recovery discrepancies (MDEV-31761)

• mariadb-binlog can now correctly process more than one logfile when --stop-datetime is specified (MDEV-35528)

• Setting pseudo_thread_id to a value exceeding 4 bytes previously resulted in truncation when written to the binary log (MDEV-35646)

Optimizer

• Fix server crash in get_sort_by_table/make_join_statistics after INSERT into a view with ORDER BY (MDEV-29935)

• Conditions with SP local variables are now pushed into derived table. Previous behaviour caused slow performance and table scans instead of using the pushed down condition (MDEV-35910)

• Fix possible hang or crash during InnoDB purge with HASH indexes during ALTER TABLE (MDEV-25654)

• EXCHANGE PARTITION now works for tables with unique blobs (MDEV-35612)

• algorithm = instant can now correctly be used if a table has partitions and one tries to change a column with an index which is not the partitions key. This previously gave error "ERROR 1846 (0A000): ALGORITHM=INSTANT is not supported. Reason: ADD INDEX. Try ALGORITHM=NOCOPY" . (MDEV-34813)

Notable Items

InnoDB

• Crash on ROLLBACK in a ROW_FORMAT=COMPRESSED table (MDEV-30882)

• UNIQUE USING HASH accepts duplicate entries for tricky collations (MDEV-30034)

• rec_get_offsets() is not optimal (MDEV-30567)

• Performance regression in fil_space_t::try_to_close() introduced in MDEV-23855 (MDEV-30775)

• InnoDB recovery hangs when buffer pool ran out of memory (MDEV-30551)

• InnoDB undo log truncation fails to wait for purge of history (MDEV-30671

• Fix miscount of doublewrites by Innodb_data_written (MDEV-31124)

Backup

• mariadb-backup doesn't utilise innodb-undo-log-directory (if specified as a relative path) during copy-back operation (MDEV-28187)

• mariadb-backup issues error messages during InnoDB tablespaces export on partial backup preparing (MDEV-29050)

• mariadb-backup does not copy Aria logs if aria_log_dir_path is used (MDEV-30968)

• Race condition between buffer pool flush and log file deletion in mariadb-backup --prepare (MDEV-30860)

Replication

• Fixed a deadlock on parallel slave involving full image Write event on the sequence engine (MDEV-29621)

• Fixed an attempted out-of-order binlogging error on slave involving ALTER on the sequence engine (MDEV-31077)

• Corrected non-versioned master to versioned slave replication on no-unique attribute table (MDEV-30430)

• Mended encrypted binlog master to error out to gtid-mode slave when master could not decrypt a binlog file (MDEV-28798)

• Refined optimistic parallel slave to error-exit without any hang (MDEV-30780)

• Ensured SHOW-SLAVE-STATUS is processed on the parallel slave having a necessary mutex always intialized (MDEV-30620)

• Fixed the slave applier to report a correct error when gtid_slave_pos insert fails for some (engine) reasons (MDEV-31038)

Optimizer

• Split Materialized optimization is improved to re-fill the materialized table only if necessary. The fewer number of table refills is taken into account when choosing query plan, too (MDEV-26301).

• Queries using SELECT DISTINCT some_expression(aggregate_function()) could produce wrong query result. (MDEV-20057)

• A GROUP BY query with MIN(primary_key) in select list and primary_key<>const in the WHERE could produce wrong result when executed with "Using index for group-by" strategy (MDEV-30605)

• EXPLAIN could erroneously report that Rowid Filter optimization is used for partitioned tables. Partitioned tables do not support it. (MDEV-30596)

• A bug in selectivity computations for SINGLE/DOUBLE_PREC_HB histograms could cause wrong estimates to be produced. This could cause the optimizer to pick sub-optimal query plans (MDEV-31067).
