I would agree that 100% guranteed messaging is really expensive. Cassandra might be good if data fit for it. For example a message can be accesed by a unique key. Otherwise you should design schema carefully.
Anyway overall performance will be bound to Cassandra's performance. If you have to store messages for a batch processing or archiving, I would suggest Kafka or ZPER. They have better performance and are simple.
