MariaDB stats and Moodle

Can the MariaDB stats provide anything useful for Moodle admins?

We can find some useful background information for Moodle Administrators considering switching from MySQL to MariaDB.

These stats are all taken from https://mariadb.org, which get the statistics from user feedback.

Operating System

Well, the first thing to note is that MariaDB is much more popular on Windows than Linux. These figures have to be thought about though … there are probably a lot more small Windows server than Linux servers.

OS Uploads
Darwin 28
FreeBSD 24
Linux 6,766
OpenVMS 8
Windows 101,150

Linux distro

The table below shows that the distributors using MariaDB are heavily slanted towards Mageia and CentOS. This is because MariaDB is the default database engine on these. It’s not so popular with Ubuntu and Debian environments, where MySQL is well established, and this is the most common Moodle environment.

Distro Uploads
lsb: Mageia 5 2,344
lsb: Mageia 6 1,767
centos: CentOS Linux release 7.5.1804 (Core)  175
os: NAME=”Red Hat Enterprise Linux Server” 128
centos: CentOS Linux release 7.4.1708 (Core)  108
centos: CentOS Linux release 7.6.1810 (Core)  100
os: PRETTY_NAME=”Debian GNU/Linux 9 (stretch)” 98
lsb: Ubuntu 16.04.4 LTS 78
SuSE: SUSE Linux Enterprise Server 12 (x86_64) 77
os: PRETTY_NAME=”Debian GNU/Linux 8 (jessie)” 73
centos: CentOS Linux release 7.3.1611 (Core)  70
centos: CentOS Linux release 7.2.1511 (Core)  64
lsb: Ubuntu 16.04.5 LTS 58
lsb: blackPanther OS v16.2SE (Silent Killer) 58
lsb: Ubuntu 16.04.3 LTS 56


What about country adoption patters? Interesting that the only European country in the top 10 is German. This might relate back to the CentOS statistics above.

It’s also interesting that Russia and the USA round out the top 3, which are far in excess of other countries. Maybe Mageia is popular in Russia?

1 Unknown 102,669
2 Russian Federation 81,038
3 Germany 67,044
4 United States of America 62,222
5 China 4,671
6 Korea 1,452
7 Indonesia 1,012
8 Mexico 919
9 India 670
10 Brazil 584

So, there is nothing here that screams “Moodle Administrators, wherever you are, consider moving to MariaDB.”

Even so, there may be good reasons, and we will start to investigate those next month.
