A lot is transferrable to NoSQL and key-value in general, though DDB has plenty of quirks of it's own. Understanding your problem really is the key. A lot of problems turn out to be quite relational after all

You definitely can build just about anything with DDB, it's often just not worth the time when most can be solved by existing tools

I'be been working with DynamoDB daily for a few years now, and whilst I like working with it and the specific scenario it solves for us, I'd still urge anyone thinking about using it to carefully reconsider whether their problem is truly unique enough that a traditional RDBMS couldn't handle it with some tuning. Theycan be unbelievably performant and give so much stuff for free.

Designing application specifically for DynamoDB will take _a lot_ of time and effort. I think we could have saved almost a third of our entire development time had we used more of the boring stuff.
