I think it's great that someone is taking a detailed look at distinct isolation levels for different systems. It's also worth looking at distinct levels for atomicity, consistency, and durability. One could then define an overall "pH" level for systems.

I would take exception to Bailis' statement that "it is impossible to simultaneously achieve high availability and serializability." At FoundationDB, we do exactly that.

I think it's rather clear that he's talking about high availability in the CAP sense, which is precisely the kind of availability FoundationDB (rightly) doesn't claim to achieve (http://foundationdb.com/#CAP).

BTW, the images are failing to load on that page for me.
