StepFunctionsStartExecutionProps Struct
Properties for StartExecution.
Example
// Define a state machine with one Pass state
const child = new sfn.StateMachine(this, 'ChildStateMachine', {
definition: sfn.Chain.start(new sfn.Pass(this, 'PassState')),
});
// Include the state machine in a Task state with callback pattern
const task = new tasks.StepFunctionsStartExecution(this, 'ChildTask', {
stateMachine: child,
integrationPattern: sfn.IntegrationPattern.WAIT_FOR_TASK_TOKEN,
input: sfn.TaskInput.fromObject({
token: sfn.JsonPath.taskToken,
foo: 'bar',
}),
name: 'MyExecutionName',
});
// Define a second state machine with the Task state above
new sfn.StateMachine(this, 'ParentStateMachine', {
definition: task,
});
Properties

Using workflow variables, you can store data in a step and retrieve that data in future steps.
associateWithParentoptionalbooleanassociate_with_parentoptionalboolassociateWithParentoptionalBooleanAssociateWithParentoptionalboolAssociateWithParentoptional*bool= false#notes
This allows the Step Functions UI to link child executions from parent executions, making it easier to trace execution flow across state machines.
If you set this property to true, the input property must be an object (provided by sfn.TaskInput.fromObject) or omitted entirely.

This enables cross-account resource invocations.

IntegrationPattern.RUN_JOB for the following exceptions: BatchSubmitJob, EmrAddStep, EmrCreateCluster, EmrTerminationCluster, and EmrContainersStartJobRun.
You can control these AWS services using service integration patterns.
Depending on the AWS Service, the Service Integration Pattern availability will vary.

notes
When specified, the value overrides the state output default. The output field accepts any JSON value (object, array, string, number, boolean, null). Any string value, including those inside objects or arrays, will be evaluated as JSONata if surrounded by {% %} characters. Output also accepts a JSONata expression directly.
