SmugMug's Don MacAskill

Been asked a few times in the last few days about where my slides are from my MySQL keynote from *last* year.

Ooops.

Um, yeah.  Sorry about that.  Here’s a link to ‘The SmugMug Tale’ slides, and you can watch the video below:

Sorry for the extreme lag.  I suck.

The important highlights go something like this:

• Use transactional replication.  Without it, you’re dead in the water. You have no idea where a crashed slave was.
• Use a filesystem that lets you do snapshots.  Easily the best way to do backups, spin up new slaves, etc. I love ZFS.  You’ll need transactional replication to really make this painless.
• Use SSDs if you can. We can’t afford to be fully deployed on SSDs (terabytes are expensive), but putting them in the write path to lower latency is awesome.  The read path might help, too, depending on how much caching you’re already doing.  Love hybrid storage pools.
• Use Fishworks (aka Open Storage) if you can.  The analytics are unbeatable, plus you get SSDs, snapshots, ZFS, and tons of other goodies.
• Use transactional replication. This is so important I’m repeating it.  Patch it into MySQL (Google, Facebook, and Percona have patches) or use XtraDB if you use replication.  We use the Percona patch.

Holler in the comments if something in the presentation isn’t clear, I’ll answer.  Apologies again.

Shameless plug – we’re hiring. And it’s a blast.
