In version 2.x you can combine CQL-statements in logged batch that is atomic. Either all or none of statements succeed. Also you can read about lightweight transactions. More than that - there are several persistence managers for Cassandra. You can achive foreign keys behavior on client level with them. For example, Achilles and Kundera.
