    Are you sure about that? DynamoDB is paxos based, so that seems unnecessary. Given data is always replicated to at least 2 of 3 storage nodes before ACK’ing, you can always just read from 2 different replicas and be sure you have the latest data.

      Oh, I thought you were referring to the multi-key consistent transactions, not single key strong consistency mode. I think you are correct.
