      It is now official. Gigaom has confirmed: eventual consistency is dying: http://gigaom.com/2013/11/02/next-gen-nosql-the-demise-of-eventual-consistency/ …

      @bascule A paper a couple of years ago purported to prove that ACID is not the bane of a distributed DB, but actually not strong enough.

      @eachus funny thing, CRDTs and other (semi)lattice structures used in eventually consistent systems have formal guarantees (without locking)

      @bascule CRDT also has some pretty strict limitations.

      @eachus it does, however Riak 2.0 added transactions and strong consistency too. k/v is still limiting though

      @bascule I understand. My point was that there is evidence that you don't actually need to sacrifice consistency to availability.

          @bascule You don't think it's possible tCAP is based on flawed assumptions? http://voltdb.com/clarifications-cap-theorem-and-data-related-errors/ … (That's not the paper I referred to.)

          @bascule Well, sure. But I was referring to the theory. We'll see how it pans out. Or if.
