AWS Amplify introduces data seeding

AWS Amplify now supports seeding data across Amazon Cognito, AWS AppSync, Amazon DynamoDB, and Amazon S3. Developers can programmatically create test users and associated resources through new APIs and a CLI command.

This feature simplifies testing and development workflows by enabling quick population of auth-dependent resources. Create Cognito users, seed DynamoDB records via AppSync with user context, and upload S3 objects - all while maintaining proper authentication relationships. This eliminates manual user creation and authentication steps previously required for testing auth-protected resources.

This feature is available in all regions where AWS Amplify is supported.
