Design considerations
One-way scheduled export
This solution automatically exports data from your primary user pool to Amazon DynamoDB on a
scheduled basis. If you create a new user pool and
populate it by running the ImportWorkflow AWS Step Functions workflow, you can configure
scheduled exports of this new user pool by launching a new instance of this solution and
configuring it to point to the new user pool.
Solution configuration
When launching the AWS CloudFormation template, there are two parameters you can use to influence the solution’s behavior.
Export frequency
This parameter sets the schedule expression for the
Amazon CloudWatch Events rule that starts the ExportWorkflow Step Functions workflow. The AWS CloudFormation
template will have options for every day, seven days, or 30 days. If you require a different
schedule, update the CloudWatch Events rule after the solution is deployed.
Cognito transactions per second (TPS)
This parameter sets the maximum number of times an Amazon Cognito API is called per second.
While the ExportWorkflow Step Functions workflow is running, API calls are made to list
users and groups in the primary user pool. When the ImportWorkflow Step Functions
workflow is running, it adds groups and adds users to groups. These API calls count against
your existing Cognito API limits. This parameter can reduce the risk of the solution
inadvertently impacting your applications. Lowering this value results in this solution
taking longer to run.
