If it knows that D is down before it starts, then it will tag the write to B or C with a "replay this row to D" hint. Otherwise, it will attempt to write to D, which will fail. Either way a QUORUM write would succeed. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
