MariaDB is a database server that offers drop-in replacement functionality for MySQL. It is built by some of the original authors of MySQL, with assistance from the broader community. In addition to the core functionality of MySQL, it offers a rich set of feature enhancements including alternate storage engines, server optimizations, and patches.
minor feature: Application period tables: WITHOUT OVERLAPS ( MDEV-16978 ) Introduce a file format constraint to ALTER TABLE. See innodb_instant_alter_column_allowed ( MDEV-20590 ). Modernise Linux Large Page support (multiplesizes) ( MDEV-18851 ). 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 ). Optimizer flag rowid_filter leads to long query ( MDEV-21794 ). WSREP_ON is unnecessarily expensive to evaluate ( MDEV-22203. Misc wsrep performance optimization ( MDEV-7962 ). Added system user for user view which allows to remove root ( MDEV-19650 ). WolfSSL updated. ALTER USER doesn't remove excess authentication plugins from mysql.global_priv ( MDEV-21928 ). mysql_upgrade creating empty global_priv table ( MDEV-21244 ). Updated aria_pack to support transactional tables and added the. --datadir. --ignore-control-file and. --require-control-file options. More details here. Error on online ADD PRIMARY KEY after instant DROP/reorder ( MDEV-21658 ). Assertion failure in file data0type.cc ( MDEV-20726 ). Server aborts upon attempt to create foreign key on spatial field ( MDEV-21792 ). DROP COLUMN, DROP INDEX is wrongly claimed to be ALGORITHM=INSTANT ( MDEV-22465 ). Introduce a file format constraint ( MDEV-20590 ). FORCE all partition to rebuild if any one of the partition does rebuild ( MDEV-21832 ). InnoDB aborts while adding instant column for discarded tablespace ( MDEV-22446 ). Misc ALTER TABLE assertion failure ( MDEV-22358 ). Optimizer, Wrong query results with. optimizer_switch="split_materialized=on" ( MDEV-21614 ). SHOW GRANTS does not quote role names properly ( MDEV-20076 ). Paritioning INSERT chooses wrong partition for RANGE partitioning by DECIMAL column ( MDEV-21195 ). Mariabackup does not honor ignore_db_dirs from server config ( MDEV-19347 ).
