I see on readwrite that Google is moving from mySQL to MariaDB. Now I know that Percona exists and has some good tooling.<p>why MariaDB and not Percona?
I actually just read a slide about why. Because Percona is still downstream of Oracle<p><a href="https://conf-slac.stanford.edu/sites/conf-slac.stanford.edu.xldb-2013/files/JCole_10.35_The%20MySQL%20Ecosystem%20at%20Scale%2016x9.pdf" rel="nofollow">https://conf-slac.stanford.edu/sites/conf-slac.stanford.edu....</a><p>I love answering my own questions.
I expect it is something to do with the fact that Percona targets small and mid-size companies who want a complete package with support but have no interest in doing their own MySQL development. But MariaDB is more open and hacker friendly. This is good for Google because they like to adapt tools to their own environment and MariaDB is more like a box of db tools in evolution.
