Q: What is a key-value store?
A key-value store is a database service that provides support for storing, querying and updating collections of objects that are identified using a key and values that contain the actual content being stored.
http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingObjects.html
Key – The name that you assign to an object. You use the object key to retrieve the object.
Value – The content that you are storing.
An object value can be any sequence of bytes. Objects can range in size from zero to 5 TB. For more information, see Uploading Objects.
