NoSQL and Partition Tolerance

I came across an article discussing NoSQL and partition tolerance - The NoSQL Partition Tolerance Myth. I may not entirely agree with the author. But what most NoSQL systems offer is a peculiar behavior that is not partition tolerant, but partition oblivious instead. No argument here. While NoSQL implementations are aware that nodes have left, they are not aware that said nodes have formed a separate partition. In this case, we would want failure detection and carry out those transfers where the accounts are both on the same side of the partition, while denying or deferring transfers that cross the chasm. The author is assuming that the account is only on one side of the partition. If that is that is case, is doesn’t matter whether the NoSQL implementation is eventually consistent or not. If the account is on both sides of the partition, the solution the author provides still results in an inconsistent state.
