    Hello @farris-kerai, 2 ways to answer your question:

    1) Contrary to your claim on AWS’ official website, 0it is actually written in the AWS’ Amazon DynamoDB landing page that Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. – https://aws.amazon.com/dynamodb/

    2) This is the necessity of understanding and appreciating purpose-built databases. What is a document anyway? When you compare them with a key-value pair, it uses the same JSON format, right? KVP is the simplest possible data model. Documents just have that structure (e.g. nesting kvp).

    In conclusion, when you try to distinguish these databases, think of potential applications, and not limitations of use.
