Buzzword headline aside, the Spanner paper is great and worth your time. As is the BigTable paper, the Dremel paper, and the Paxos Made Live paper.
I read the Google whitepapers and wonder, is there anywhere else one can go to work on real solutions to distributed systems problems? At smaller scales you can cheat -- you don't need Paxos, you can get away with non-consensus-based master / slave failover. You can play the odds with failure modes. At Google's scale, you can't: behavior under normally unlikely failures matters, probability matters, CAP matters.
