This is the video I recommend to others when working with dynamodb. The video is by Rick Houlihan about dynamodb modeling. In my experience most developers that complain about dynamodb don't fully understand it.

DynamoDB can model relational data just fine, if you're okay with setting your query access patterns in stone and never changing them again.

And many developers don't fully understand that he's a good salesman and can't see through the BS.

All technologies have their pros and cons. They have use cases where they make sense and use case where they don't. The job of an engineer to decide which tool fits which use-case. To dismiss a useful technology as "BS", especially one used by companies all over the world for over a decade without any backing data seems a bit disingenuous.

Exactly. But that's not how he paints it, I have seen him bashing RDBMs as been a thing of the past and his promoted way of data modeling and "new" database technology is how companies should start today or be moving to.
