I bought this a few weeks ago and am about 130 pages in.

It is just stunning how much better it is learning Dynamo/NoSQL in general from this than effectively any other source. Anyone who's had to rely on AWS docs knows how face-meltingly dense they can be.

I went back and refactored all my previous Dynamo work last night, and the difference was night and day. I'm planning to migrate some relational structures later this week, as well.

Is good book.
