Large-scale parallel processing

With Step Functions, you can orchestrate large-scale parallel processing. These parallel workloads let you concurrently process large-scale data sources stored in Amazon S3.
A Map state set to Distributed is known as a Distributed Map state. In Distributed mode, the Map state allows high-concurrency processing. In Distributed mode, the Map state processes the items in the dataset in iterations called child workflow executions.

Start by reading the linked AWS Step Functions documentation on Distributed Map states and then inspect the repository's existing AWS Batch and FFmpeg workflow. The issue does not identify files, entry points, tests, or a concrete completion condition, so the intended implementation remains undefined.
