Managing queues with cassandra is a known antipattern because of how cassandra marks deletes as tombstones and navigating through the queu will have to scan the previous tombstones to fetch the next slice

Having said that astyanax has a recipe to write durable queues to Cassandra, could be interesting finding if it is possible to convert that to CQL and if it is not affected by the tombstone issue
