Prototyping your application’s data model with Amazon DynamoDB has just gotten simpler with sample data generation using NoSQL Workbench for Amazon DynamoDB. The ability to generate sample data enables you to create realistic demos and test your application access patterns under conditions that closely simulate a production environment. You can use NoSQL Workbench to generate sample data to visualize if your data model design and item collections will fulfill your application’s access patterns. During application development you will also want to test that your application can function and handle use cases with enough data. NoSQL Workbench helps you generate the volume and variety of data that you will need to test your code. You can directly deploy your data models with sample data to Amazon DynamoDB and DynamoDB local, or download the sample data as a CSV file for later use.
