I'm really excited about the price reduction and the reserved throughput possibilities. Over the past six months I slowly but surely migrated most of the core data storage for the startup I work for to DynamoDB and I have been very satisfied with the performance. That said I agree with the post that DynamoDB isn't suited for every use case, just like MySQL and other relational databases aren't suited for every use case. We are still using MySQL for log tables and other tables in which we need to do complex queries over time ranges with tests on multiple properties. The sweet spot is combining DynamoDB and a relational database into a seamless system that lets you use the power and scalability of DynamoDB when all that is needed is a simple lookup, and the complex queries of SQL when you need a detailed time range based report.
