does the mysql/mariadb comparison actually make sense? mysql is not really a downstream distro of mariadb (maaybe even the opposite?) so i thought i understood the situation as presented until that paragraph
The way I remember it, was that MySQL was sold, then some time after, MariaDB was created as a fork, and you could switch between them. Then at one point MariaDB diverged sufficiently that you could no longer "effortlessly" (kinda) switch between them, by now they're separate but MariaDB's origin is still MySQL obviously.
My, Maria, and Max are his kids. There is MaxScale which is a L7 SQL proxy/loadbalancer
