I've found just the opposite actually. While it's far from perfect, it has been amazing for rapidly standing up new apps (especially prototypes). We've used quite a few different strategies and found it to be flexible and performant.

The only downside is we do find ourselves sometimes implementing relational DB functionality at the application level to compensate for Dynamo DB's "flexibility." Postgres is still the go-to for data that is relational in nature. But man, letting Amazon worry about hosting and scaling is also pretty awesome...

Yep, this is A-grade crazy, and exactly my point. I would question if it's "sometimes", or "actually almost all the time, now that we think about it, there's not much that we CAN do with DynamoDB without writing application level database functionality."

Prototypes are far bettered suited with Postgres or Mysql on RDS. When you don't know your schema or your use case upfront, traditional databases are far easier to work with, since you can change them. Once you know what your doing scaling up works far better on something like Dynamo or Cassandra, but you will be sacrificing dev time
