### Monitor Execution

Monitor the execution in the AWS Step Functions console. The Distributed Map view shows all 50 child executions and their status. Each child invokes the durable function synchronously with a unique `DurableExecutionName`. Results are written back to the Amazon S3 bucket under the `results/` prefix.
