Good article. In many ways, I think the author is echoing the same frustrations as with Google App Engine's Datastore ( http://news.ycombinator.com/item?id=3431132 http://news.ycombinator.com/item?id=3431132 App Engine charges $6,500 to update a ListProperty on 14.1 million entities ). Both Google Datastore and the new AWS DynamoDB are great, fast services, but they are a bit too expensive at the medium/high end. Frankly, I wish App Engine/AWS/Heroku/etc would introduce a database that traded speed for cheaper costs. I'd be fine with certain writes being delayed if it meant lower costs.
