Sort of: if the coordinator knows when it begins processing the request that B is down, it will write a hint. But if it has not yet detected that B is down, then it will attempt a write. If the write times out then no further attempts are made. -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
