Maria (storage engine)
Encyclopedia
Aria is a storage engine for the MySQL
relational database management system
. Its goal is to make a crash-safe alternative to MyISAM
. It is not yet transactional
but plans to add proper support for database transactions at some point in the future. The long-term goal is for Aria to be the default transactional and non-transactional storage engine for MySQL. It has been in development since 2007 and was first announced by Michael "Monty" Widenius
on his blog. Aria is the default storage engine of MariaDB
, a community-developed branch of the MySQL database led by Widenius.
The Maria project is hosted on Launchpad.
Aria was initially named 'Maria', as a reference to Monty's youngest child.
It was renamed Aria in 2010 to avoid confusion with the main database it is developed for.
