Nextcloud asked in a poll at https://mastodon.social/@nextcloud@mastodon.xyz/115095096413238457 what database its users are running. Interestingly one fifth replied they don’t know. Should people know better where their data is stored, or is it a good thing everything is running so smoothly people don’t need to know what their software stack is built upon?
My instance did required me to fix some db issue after an update(it still works but the fix was recommended*). So I knew I am using mariadb. Its not super smooth sailing.
