No, batch_mutate() is an atomic operation. When a node locally applies a batch mutation, either all of the changes are applied or none of them are. Aaron was referring to the possibility that one of the replicas received the batch_mutate, but the other replicas did not. -- Tyler Hobbs DataStax <http://datastax.com/>
