Introduction to the main differences

Features MariaDB MySQL
Distribution MariaDB is a branch of MySQL MySQL is a product of Oracle Corporation
Development Company MariaDB is maintained by the MariaDB Foundation and Community MySQL is maintained by Oracle Corporation
It should be noted that although there are many differences between MariaDB and MySQL , they can be used interchangeably in most situations because they have the same SQL syntax and functionality.

Incompatible features between the two

  • Storage engine: MariaDB contains some storage engines that MySQL does not have, such as Aria, ColumnStore, and MyRocks. These storage engines may not be compatible with MySQL's storage engine.

  • Data types: MariaDB contains some data types that MySQL does not have, such as JSON, XML and UUID. If your application relies on these data types, you need to consider whether they are available in MySQL.

  • Functions and operators: MariaDB contains some functions and operators that MySQL does not have, such as PCRE regular expressions and BIT_XOR functions. If your application uses these functions and operators, you need to consider whether they are available in MySQL.

  • System variables and options: MariaDB contains some system variables and options that MySQL does not have, such as max_statement_time and innodb_adaptive_flushing. If your application relies on these variables and options, you need to consider whether they are available in MySQL.

It is important to note that despite these incompatible features and functionality, MariaDB still strives to maintain compatibility with MySQL and provides many compatibility layers to ensure that applications can run smoothly Migrate from MySQL to MariaDB easily.

InnoDB supports page-level compression with a high compression rate InnoDB supports row-level compression and the compression rate is low
MariaDB has a better caching mechanism and can automatically adjust the cache size as needed MySQL’s caching mechanism is relatively simple
MariaDB supports full-text search index, using the InnoDB engine MySQL supports full-text search Index, but does not support using
MariaDB supports a wider variety of partitioning strategies, such as by month, day, and by key value MySQL supports relatively few partition strategies
MariaDB supports more kinds of backups, including hot backup and incremental backup MySQL backup is relatively simple
MariaDB has better performance in some cases, such as using multiple threads for queries MySQL may perform better in some cases, such as on certain types of queries
