Default is eventually consistent.

GetItem provides an eventually consistent read by default. If your application requires a strongly consistent read, set ConsistentRead to true.


Another great example is DNS (see following). Maybe not what you think of when you think database, however it is a true BASE architecture.

The most popular system that implements eventual consistency is DNS (Domain Name System). Updates to a name are distributed according to a configured pattern and in combination with time-controlled caches; eventually, all clients will see the update.
