Spanner

Google:

Spanner is Google’s scalable, multi-version, globally-distributed, and synchronously-replicated database. It is the first system to distribute data at global scale and support externally-consistent distributed transactions. This paper describes how Spanner is structured, its feature set, the rationale underlying various design decisions, and a novel time API that exposes clock uncertainty. This API and its implementation are critical to supporting external consistency and a variety of powerful features: non-blocking reads in the past, lock-free read-only transactions, and atomic schema changes, across all of Spanner.

Via High Scalability, which notes:

We see most of the criticisms leveled against NoSQL turned out to be problems for Google too. Only Google solved the problems in a typically Googlish way, through the fruitful melding of advanced theory and technology. The result: programmers get the real transactions, schemas, and query languages many crave along with the scalability and high availability they require.
