CDK Step Function Map state working with "Distributed Mode"

Update: As Anentropic pointed out, the CDK Construct has been released: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.DistributedMap.html

Hi Umut,

as of today, Distributed Map isn't supported by the CDK yet (https://github.com/aws/aws-cdk/issues/23216). However, you can always use the CustomState construct to drop in any ASL that’s not natively implemented in the L2 constructs.

For example:

const custom = new sfn.CustomState(this, 'distributed map state', {
  stateJson: { 
    "Type": 'Map',
    "ItemReader": {
      "ReaderConfig": {
        "InputType": "CSV",
        "CSVHeaderLocation": "FIRST_ROW"
      },
      "Resource": "arn:aws:states:::s3:getObject",
      "Parameters": {
         ...
      }
    },
    "ItemProcessor": {
      "ProcessorConfig": {
        "Mode": "DISTRIBUTED",
        "ExecutionType": "EXPRESS"
      },
      "StartAt": "...",
      "States": {
          ....
        }
      }
    }
  }
});
