Map

Use the Map state to run a set of workflow steps for each item in a dataset. The Map state's iterations run in parallel, which makes it possible to process a dataset quickly. Map states can use a variety of input types, including a JSON array, a list of Amazon S3 objects, or a CSV file.

Step Functions provides two types of processing modes for using the Map state in your workflows: Inline mode and Distributed mode.

For information about these modes, and how to use the Map state in either mode, see the following topics:

Tip

To deploy an example of a workflow that uses a Map state to your Amazon Web Services account, see Module 5 - Choice State and Map State of The Amazon Step Functions Workshop.
