MariaDB originated as a fork of MySQL, after it was taken over by Oracle. For an overview of the differences between MariaDB and MySQL, go to this one and this one pages right. MariaDB is a powerful open source database server, which is especially popular as a website and forum database. The developers have version versions 10.9.2the first stable release of the 10.9 series, and 10.10.1 released. The latter is still offered as a release candidate. The most important changes and improvements made in version 10.9.2 are listed below:



  • ER_SLAVE_INCIDENT error is specified now on slave to be seen with SHOW-SLAVE-STATUS (MDEV-21087)
  • INCIDENT_EVENT is no longer binlogged when a being logged transaction can be safely rolledback (MDEV-21443)
  • sequences related row-format events are made to correspond to binlog_row_image (MDEV-28487)
  • Possible reason of FLUSH BINARY LOGS hang is eliminated (MDEV-28948)
  • Fix out-of-order gtid error in the circular semisync setup (MDEV-28609)


  • Possible to write/update with read_only=ON and not a SUPER privilege (MDEV-28546)
  • Node crashes with Transport endpoint is not connected mysqld got signal 6 (MDEV-25068)
  • Galera4 not able to report proper wsrep_incoming_addresses (MDEV-20627)
  • Galera should replicate nextval()-related changes in sequences with INCREMENT <> 0, at least NOCACHE ones with engine=InnoDB (MDEV-27862)
  • Add support for OpenSSL 3.0 in Galera (MDEV-25949)


  • Server crash in JOIN_CACHE::free or in copy_fields (MDEV-23809)
    • Queries that use DISTINCT and an always-constant function like COLLATION(aggegate_func(…)) could cause a server crash. Note that COLLATION() is a special function – its value is constant even if its argument is not costant.
  • Crash when using ANY predicand with redundant subquery in GROUP BY clause (MDEV-29139)
    • A query with a subquery in this form could cause a crash:

… ANY (SELECT … GROUP BY (SELECT redundant_subselect_here)) …

  • MariaDB Server SEGV on INSERT .. SELECT (MDEV-26427)
    • Certain queries in form “INSERT … SELECT with_aggregate_or_window_func” could cause a crash.
  • restore_prev_nj_state() doesn’t update cur_sj_inner_tables correctly (MDEV-28749)
    • Subquery semi-join optimization could miss LooseScan or FirstMatch strategies for certain queries.
  • Optimizer uses all partitions after upgrade to 10.3 (MDEV-28246)
    • For multi-table UPDATE or DELETE queries, the optimizer failed to apply Partition Pruning optimization for the table that is updated or deleted from.
  • Range optimizer regression for key IN (const, ….) (MDEV-25020)
    • The issue can be observed on MariaDB 10.5.9 and later versions which have the fix for MDEV-9750. That fix introduced optimizer_max_sel_arg_weight.
    • If one sets optimizer_max_sel_arg_weight to a very high value or zero (which means “unlimited”) and runs queries that produce heavy-weight graphs, they can observe a performance slowdown, eg:

table.keyXpartY [NOT] IN ( … )

  • Wrong result with table elimination combined with not_null_range_scan (MDEV-28858)
    • If one runs with optimizer_switch=”not_null_range_scan=on” (which is not enabled by default), a query that does a join and has const tables could produce a wrong result.
  • Assertion `tmp >= 0′ failed in best_access_path (MDEV-28882)
    • If one uses histogram_type=JSON_HB, has collected a histogram of that type and runs a query that selects a very narrow range near histogram end, they can hit an assertion in the optimizer due to rounding errors in the histogram causing negative selectivity.



  • JSON_TABLE: extract document fragment into JSON column (MDEV-25875)
