DynamoDB is an incredibly powerful NoSQL database. It’s schema-less, which gives you lots of flexibility, but it also means that you are responsible for managing the integrity of your data. This includes ensuring the structure of your data, as well as the ability to preserve metadata throughout your data’s lifecycle.
