It was announced there would be a video soon but I was not able to find it.

The video can be found at:

And the Q&A after the talk is at:

Funny that they both managed to be close to 15 minutes on the dot and I didn't use any timers :)

"* You can't have multiple masters"

The ability to have multiple masters has been around for some years now: http://dev.mysql.com/doc/refman/5.0/en/replication-options-m...

That isn't a ring topology or based on a timer?

No. Each master has an offset so when you build a ring you give each master a different starting point. This keeps your ids in sync. So master1 would create ids: 1, 11, 21, 31, 41, 51, etc... and master2 would create ids: 2, 12, 22, 32, 42, 52, etc...
