Well, if you're looking for a solution where the whole cluster is perfectly/strongly consistent, then BDR is not for you I guess. What BDR gives you is a guarantee that the changes are applied atomically (i.e. matching transactions from the source node), and in the commit order. But there's no global consistency guarantee - that's a consequence of of the asynchronous behavior.
