DynamoDB: Set Up, Secondary Indexes and Read/Write Capacity.

The AWS DynamoDB is the fully managed NoSQL database offering from Amazon. This is excellent for organizations that do not want to manage their NoSQL databases.

An employee ID is likely to provide a unique value across all employees. Duplicated keys will cause problems because you can’t uniquely identify a particular piece of data after the key is duplicated. A key must also provide a simple value.
