I think there are two possible questions here, so I will answer both of them.
- If there is a question, can I access RDS from a Cognito application with auth:
RDS does not use AWS credentials for authentication, it uses database credentials. Cognito only uses credentials for AWS, so you cannot use Cognito credentials to access the RDS database.
- If the question arises, can I associate RDS with Cognito so that I can query, manipulate, or analyze the data sets of your end users:
Access to user data sets is through Cognito. There is no export function or link that allows you to use RDS.
