So you are aware, yours is the traditional response. Somehow, doing what Google and Facebook do is "easy" because not everything requires transactions. This is false both because scale like that makes almost everything difficult, and because, as Google recently published, they are using transactions for their main application. NoSQL does not imply lack of transactions and transactions do not imply relational databases.

"Databases do not meet the storage or throughput requirements of these tasks"

And Mongo or Redis? Come on, scro.

The post you are replying to does not contain the word "easy" at all, so far as I can discern. I think you might be attacking a straw man.
