Data Matters

The official document of mariadb does not mention the default CREATE TABLE options for tables using Aria Engine.  The default options are list as below: TRANSACTIONAL,  the default value is TRANSACTIONAL=0, i.e., non-transactional. ROW_FORMAT, the default value is ROW_FORMAT=PAGE, which may suits both transactional and non-transactional tables. PAGE_CHECKSUM,  the default value will follow aria_page_checksum system variable, which has default value ON. For the TRANSACTIONAL option, you may consider create a table as below(and ALTER the TRANSACTIONAL=1): CREATE TABLE `test_table` ( `id` int(11) NOT NULL AUTO_INCREMENT, PRIMARY KEY (`id`) ) ENGINE=Aria; If you change the ROW_FORMAT to DYNAMIC or FIXED, everything just goes fine. But if you have ALTER the table with TRANSACTION=1 and change the ROW_FORMAT to DYNAMIC or FIXED, you may got a warning: SHOW WARNINGS; +-------+------+----------------------------------------------------------+ | Level | Code | Message | +-------+--

You need to previously set the root password echo mariadb-server-5.5 mysql-server/root_password password xxxxx | sudo debconf-set-selections echo mariadb-server-5.5 mysql-server/root_password_again password xxxxx | sudo debconf-set-selections And then sudo apt-get -y install mariadb-server If you are going to uninstall mariadb totally, you may sudo apt-get purge mariadb* && sudo apt-get autoremove

mysql-python requires libmysqlclient-dev in ubuntu, but the installation of mariadb will have the lib with unmet dependenccies, so the error of "mysql_config not found" may occurred if you install mysql-python via pip. The case is that mariadb has a compatible package, if you have the ppa setup as in  http://downloads.mariadb.org/ . Just "sudo apt-get install libmariadbclient-dev".
