This workflow is an example application of a step function using distributed map. This distributed map iterates over an CSV file that is stored in an S3 bucket.
The state machine will take as an input a CSV file that contains a header and multiple items. For each item, the Map state runs each iteration as a child workflow execution, which enables high concurrency of up to 10,000 parallel child workflow executions.
Each of the Map state will add the item to a DynamoDB table. But you can do more complex things in this state machine.
