- Amazon DynamoDB is a fully managed proprietary NoSQL database service that supports key–value and document data structures and is offered by Amazon.com as part of the Amazon Web Services portfolio.[1] DynamoDB exposes a similar data model to and derives its name from Dynamo, but has a different underlying implementation. Dynamo had a multi-leader design requiring the client to resolve version conflicts and DynamoDB uses synchronous replication across multiple data centers for high durability and availability. DynamoDB was announced by Amazon CTO Werner Vogels on January 18, 2012,[2] and is presented as an evolution of Amazon SimpleDB.

- Q: What kind of NoSQL database is AWS DynamoDB? Is it document type or key-value type?
- A: To begin with, there are not a lot of differences between Key Value and Document Type No-SQL databases. Key Value DBs are considered for more ‘primitive’ data type agnostic use cases i.e it really does not matter to your application whether you store a blob, xml, json or any other data types. Document Type databases, on the other hand offer specialized capabilities built around the pre-understanding of data types in the value field. Eg. MongoDB/Mapr-DB supports JSON and offer auto-indexing of JSON fields.
AWS dynamoDB falls more as a latter type. There are additional capabilities offered by AWS DynamoDB eg. auto setup of Secondary index built around the understanding of data type that will place itself more as a ‘Document Type No-SQL’
