NoSQL database solutions are only useful for event streams. Nothing else. Wrestling with DynamoDB to try and filter a complex query is unnecessarily complex .

No, they are useful for many things depending on which you use.

But before use one, make sure to check out what cases its designed for and what it is not good for.

Often it could be a good idea to use more than one for different parts of the database.

We built a fairly competent web application on mongodb, and most of it was very easy, but a few tasks proved extra ordinally difficult to achieve.

Range queries with overlapping ranges :/
