I've used MariaDB in production a few years back and didn't notice any differences in operation except for an esoteric bug with some version of Ubuntu that required making a minor change to the config file...otherwise, it worked as a drop-in replacement as advertised, though this app didn't do anything particularly exotic outside of the standard Rails/ActiveRecord conventions...<p>Has much changed? Is MariaDB still pretty much a drop-in replacement? And has anyone moved a non-trivial app from MySQL to MariaDB...or would be confident in making that move on RDS, on the heels of this announcement? I mean, if there aren't any production problems, the change in licensing [1] alone seems like it could be enough of a reason (although I may be misunderstanding MySQL's licensing, it's always been a little confusing to me).<p>[1] <a href="http://stackoverflow.com/a/227242" rel="nofollow">http://stackoverflow.com/a/227242</a>
Apparently this doesn't include the version that comes with data at rest encryption (10.1.3):<p><a href="https://mariadb.com/kb/en/mariadb/data-at-rest-encryption/" rel="nofollow">https://mariadb.com/kb/en/mariadb/data-at-rest-encryption/</a>
