Need to be careful about the wording, "strong consistency". I dislike that datastax uses that in their documentation, because it's misleading and really confuses people. There is no commit protocol in place - Cassandra is still an AP db under the hood, so even having multiple replicas acknowledge doesn't mean the data is consistent. For that you need paxos or something similar. This becomes very obvious if you are doing updates from multiple sources to the same key.
