Options

--dag-nodes (list)

A list of the nodes in the DAG.

(structure)

Represents a node in a directed acyclic graph (DAG)

Id -> (string)

A node identifier that is unique within the node’s graph.

NodeType -> (string)

The type of node that this is.

Args -> (list)

Properties of the node, in the form of name-value pairs.

(structure)

An argument or property of a node.

Name -> (string)

The name of the argument or property.

Value -> (string)

The value of the argument or property.

Param -> (boolean)

True if the value is used as a parameter.

LineNumber -> (integer)

The line number of the node.

Shorthand Syntax:

Id=string,NodeType=string,Args=[{Name=string,Value=string,Param=boolean},{Name=string,Value=string,Param=boolean}],LineNumber=integer ...

JSON Syntax:

[
  {
    "Id": "string",
    "NodeType": "string",
    "Args": [
      {
        "Name": "string",
        "Value": "string",
        "Param": true|false
      }
      ...
    ],
    "LineNumber": integer
  }
  ...
]

--dag-edges (list)

A list of the edges in the DAG.

(structure)

Represents a directional edge in a directed acyclic graph (DAG).

Source -> (string)

The ID of the node at which the edge starts.

Target -> (string)

The ID of the node at which the edge ends.

TargetParameter -> (string)

The target of the edge.

Shorthand Syntax:

Source=string,Target=string,TargetParameter=string ...

JSON Syntax:

[
  {
    "Source": "string",
    "Target": "string",
    "TargetParameter": "string"
  }
  ...
]

--language (string)

The programming language of the resulting code from the DAG.

Possible values:

• PYTHON

• SCALA

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

PythonScript -> (string)

The Python script generated from the DAG.

ScalaCode -> (string)

The Scala code generated from the DAG.
