MariaDB version numbers follow MySQL's numbering scheme up to version 5.5. Thus, MariaDB 5.5 offers all of the MySQL 5.5 features. There exists a gap in MySQL versions between 5.1 and 5.5, while MariaDB issued 5.2 and 5.3 point releases.
MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [6] is an open-source relational database management system (RDBMS). [6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language.

[2] [3] It provides the standard ACID-compliant transaction features, along with foreign key support (declarative referential integrity). It is included as standard in ...

[71] [72] Note (3): "For other than InnoDB storage engines, MySQL Server parses and ignores the FOREIGN KEY and REFERENCES syntax in CREATE TABLE statements. The CHECK clause is parsed but ignored by all storage engines." [73]
However, the MariaDB developers still work on MyISAM code. The major improvement is the "Segmented Key Cache". [4] If it is enabled, MyISAM indices' cache is divided into segments. This improves the concurrency because threads rarely need to lock the entire cache. In MariaDB, MyISAM also supports virtual columns. Drizzle does not include MyISAM.
