Look at the example DataModels in integration. The pattern is the same: load it all into memory! it's too slow for real-time otherwise. So there is no point in say moving your data from a DB to Dynamo for "scalability" if you're using non-distributed code. If you're using Hadoop, DataModel is not relevant.
