@blackfriday We made MariaDB a requirement because MySQL lacked microsecond precision at that time. You can try if to use MySQL >= 5.6, however we don’t officially support MySQL. Also, we might use a MariaDB feature in future. So it is better to stick with MariaDB. In fact, MariaDB should play well with your other software, as it is compatible with MySQL and provides a much more stable InnoDB implementation called XtraDB (by Percona).
Ok, got the point here.
What i want to know is, can MySQL co-exist with MariaDB in same server? Will there be any problem later? Any special tips on having both database on same server?
