Let me start by saying that DynamoDB is by far the most aggressively priced cloud service. It charges per throughput (read write) units assigned to a table on an hourly basis which makes it really expensive to use. On the other side, it provides supreme scalability with extremely low latency as the catalogue claims which has been true for most of our production workloads in the last 3 years that we have run with it. DDB is a great columnar store alternative.Their query API Is gradually maturing and is now way more useful to get most job done.

+1 for aggressive pricing. If you are looking for a fully managed NoSQL, Google Cloud Datastore might be a good alternative - https://cloud.google.com/datastore/
