The DynamoDB Book I had always dismissed DynamoDB as a simple key-value store. But this book (which is like a developer's guide) opened my eyes to how powerful DynamoDB can be if you use it in the right way for the right problems. One of the many interesting things about it is that DynamoDB won't let you write slow queries. It constrains the kinds of queries you can write in such a way that each operation has an upper limit on latency. It simply does not allow the kinds of queries that could take a while (>25ms) to execute.
