Nerval's Lobster writes: MariaDB is a fork of the MySQL source code, split off in the wake of concerns over what Oracle would do with MySQL licensing. In addition to its role as a “drop-in replacement” for MySQL, MariaDB also includes some new features that (some claim) make it better than MySQL. Jeff Cogswell compares MySQL and MariaDB and suggests (in his opinion) that there's "more than enough reason to ditch MySQL and switch over to MariaDB and stay there." Why? While he breaks down MariaDB's new features and thinks many of them aren't that fantastic, and while MariaDB's performance isn't that much better than that of MySQL ("MariaDB’s performance appears a bit better on multi-core machines, but I strongly suspect that one could tweak MySQL to match"), the questions over Oracle and MySQL licensing give him pause. "MariaDB shows every indication that it will be around for quite awhile, while you can’t really say the same of Oracle’s MySQL," he writes. "Free-and-open MySQL competes with Oracle’s proprietary and extremely competitive tools. That alone is grounds for concern—will Oracle do something to impede MySQL’s development?"
