Amazon DynamoDB

DynamoDB vs MongoDB: which is better for flexible schemas?

The question is about Amazon DynamoDB .

Answer:
MongoDB provides document-oriented storage with fully flexible, dynamic schemas, letting you rapidly adapt or change data models on the fly - ideal when the structure frequently evolves. DynamoDB also offers a flexible schema for items, but it is stricter about indexing, key usage, and is best suited to predictable access patterns. For quick development and frequent structural changes, MongoDB is often better; for simple, fast schema-less models at scale, DynamoDB is a top option.
