Which database system Wikipedia is currently using?

MariaDB is a fork of MySQL by Monty (original MySQL author)

MySQL

Well, MySQL plus a text store.

MediaWiki, the open source software that Wikipedia uses, now officially supports MariaDB.

We're also using OpenStack Swift for media storage these days.

I couldn't see a way to aggregate it in the ganglia linked.. could you share how many mysql (maria) queries per second you guys are averaging?

I should clarify: I used to work there but I sometimes still say "we".

I'm not a ganglia wizard - maybe this comes close? Although it's just all selects. I think.

You might try asking on wikitech-l, the same mailing list that the original post comes from.

I use MariaDB on my Mac for most things that require MySQL. It's a drop in replacement for most things. Is there a special edge case with media wiki they had to solve or is it now just formally announced as being supported?

So, it's pretty much a drop-in replacement. But as with everything, time m ust be spent testing and so on before rolling it out to production. I believe a transition to MariaDB has been planned for a while now.

I remember I had problems with insert statements when previously with mysql inserts without default values worked but MariaDB was strict in this case and these inserts failed...
