Tasks for AWS Step Functions

AWS Step Functions is a web service that enables you to coordinate the components of distributed applications and microservices using visual workflows. You build applications from individual components that each perform a discrete function, or task, allowing you to scale and change applications quickly.

A Task state represents a single unit of work performed by a state machine. All work in your state machine is performed by tasks. This module contains a collection of classes that allow you to call various AWS services from your Step Functions state machine.

Be sure to familiarize yourself with the aws-stepfunctions module documentation first.

This module is part of the AWS Cloud Development Kit project.

Evaluate Expression

Use the EvaluateExpression to perform simple operations referencing state paths. The expression referenced in the task will be evaluated in a Lambda function (eval()). This allows you to not have to write Lambda code for simple operations.

Example: convert a wait time from milliseconds to seconds, concat this in a message and wait:

convertToSeconds := tasks.NewEvaluateExpression(this, jsii.String("Convert to seconds"), &EvaluateExpressionProps{
	Expression: jsii.String("$.waitMilliseconds / 1000"),
	ResultPath: jsii.String("$.waitSeconds"),
})

createMessage := tasks.NewEvaluateExpression(this, jsii.String("Create message"), &EvaluateExpressionProps{
	// Note: this is a string inside a string.
	Expression: jsii.String("`Now waiting ${$.waitSeconds} seconds...`"),
	Runtime: lambda.Runtime_NODEJS_LATEST(),
	ResultPath: jsii.String("$.message"),
})

publishMessage := tasks.NewSnsPublish(this, jsii.String("Publish message"), &SnsPublishProps{
	Topic: sns.NewTopic(this, jsii.String("cool-topic")),
	Message: sfn.TaskInput_FromJsonPathAt(jsii.String("$.message")),
	ResultPath: jsii.String("$.sns"),
})

wait := sfn.NewWait(this, jsii.String("Wait"), &WaitProps{
	Time: sfn.WaitTime_SecondsPath(jsii.String("$.waitSeconds")),
})

sfn.NewStateMachine(this, jsii.String("StateMachine"), &StateMachineProps{
	Definition: convertToSeconds.Next(createMessage).Next(publishMessage).*Next(wait),
})

The EvaluateExpression supports a runtime prop to specify the Lambda runtime to use to evaluate the expression. Currently, only runtimes of the Node.js family are supported.

API Gateway

Step Functions supports API Gateway through the service integration pattern.

HTTP APIs are designed for low-latency, cost-effective integrations with AWS services, including AWS Lambda, and HTTP endpoints. HTTP APIs support OIDC and OAuth 2.0 authorization, and come with built-in support for CORS and automatic deployments. Previous-generation REST APIs currently offer more features. More details can be found here.

Call REST API Endpoint

The CallApiGatewayRestApiEndpoint calls the REST API endpoint.

import apigateway "github.com/aws/aws-cdk-go/awscdk"

restApi := apigateway.NewRestApi(this, jsii.String("MyRestApi"))

invokeTask := tasks.NewCallApiGatewayRestApiEndpoint(this, jsii.String("Call REST API"), &CallApiGatewayRestApiEndpointProps{
	Api: restApi,
	StageName: jsii.String("prod"),
	Method: tasks.HttpMethod_GET,
})

Be aware that the header values must be arrays. When passing the Task Token in the headers field WAIT_FOR_TASK_TOKEN integration, use JsonPath.array() to wrap the token in an array:

import apigateway "github.com/aws/aws-cdk-go/awscdk"
var api restApi


tasks.NewCallApiGatewayRestApiEndpoint(this, jsii.String("Endpoint"), &CallApiGatewayRestApiEndpointProps{
	Api: Api,
	StageName: jsii.String("Stage"),
	Method: tasks.HttpMethod_PUT,
	IntegrationPattern: sfn.IntegrationPattern_WAIT_FOR_TASK_TOKEN,
	Headers: sfn.TaskInput_FromObject(map[string]interface{}{
		"TaskToken": sfn.JsonPath_array(sfn.JsonPath_taskToken()),
	}),
})
Call HTTP API Endpoint

The CallApiGatewayHttpApiEndpoint calls the HTTP API endpoint.

import apigatewayv2 "github.com/aws/aws-cdk-go/awscdk"

httpApi := apigatewayv2.NewHttpApi(this, jsii.String("MyHttpApi"))

invokeTask := tasks.NewCallApiGatewayHttpApiEndpoint(this, jsii.String("Call HTTP API"), &CallApiGatewayHttpApiEndpointProps{
	ApiId: httpApi.ApiId,
	ApiStack: awscdk.*stack_Of(httpApi),
	Method: tasks.HttpMethod_GET,
})
AWS SDK

Step Functions supports calling AWS service's API actions through the service integration pattern.

You can use Step Functions' AWS SDK integrations to call any of the over two hundred AWS services directly from your state machine, giving you access to over nine thousand API actions.

var myBucket bucket

getObject := tasks.NewCallAwsService(this, jsii.String("GetObject"), &CallAwsServiceProps{
	Service: jsii.String("s3"),
	Action: jsii.String("getObject"),
	Parameters: map[string]interface{}{
		"Bucket": myBucket.bucketName,
		"Key": sfn.JsonPath_stringAt(jsii.String("$.key")),
	},
	IamResources: []*string{
		myBucket.ArnForObjects(jsii.String("*")),
	},
})

Use camelCase for actions and PascalCase for parameter names.

The task automatically adds an IAM statement to the state machine role's policy based on the service and action called. The resources for this statement must be specified in iamResources.

Use the iamAction prop to manually specify the IAM action name in the case where the IAM action name does not match with the API service/action name:

listBuckets := tasks.NewCallAwsService(this, jsii.String("ListBuckets"), &CallAwsServiceProps{
	Service: jsii.String("s3"),
	Action: jsii.String("listBuckets"),
	IamResources: []*string{
		jsii.String("*"),
	},
	IamAction: jsii.String("s3:ListAllMyBuckets"),
})

Use the additionalIamStatements prop to pass additional IAM statements that will be added to the state machine role's policy. Use it in the case where the call requires more than a single statement to be executed:

detectLabels := tasks.NewCallAwsService(this, jsii.String("DetectLabels"), &CallAwsServiceProps{
	Service: jsii.String("rekognition"),
	Action: jsii.String("detectLabels"),
	IamResources: []*string{
		jsii.String("*"),
	},
	AdditionalIamStatements: []policyStatement{
		iam.NewPolicyStatement(&PolicyStatementProps{
			Actions: []*string{
				jsii.String("s3:getObject"),
			},
			Resources: []*string{
				jsii.String("arn:aws:s3:::my-bucket/*"),
			},
		}),
	},
})

Athena

Step Functions supports Athena through the service integration pattern.

StartQueryExecution

The StartQueryExecution API runs the SQL query statement.

startQueryExecutionJob := tasks.NewAthenaStartQueryExecution(this, jsii.String("Start Athena Query"), &AthenaStartQueryExecutionProps{
	QueryString: sfn.JsonPath_StringAt(jsii.String("$.queryString")),
	QueryExecutionContext: &QueryExecutionContext{
		DatabaseName: jsii.String("mydatabase"),
	},
	ResultConfiguration: &ResultConfiguration{
		EncryptionConfiguration: &EncryptionConfiguration{
			EncryptionOption: tasks.EncryptionOption_S3_MANAGED,
		},
		OutputLocation: &Location{
			BucketName: jsii.String("query-results-bucket"),
			ObjectKey: jsii.String("folder"),
		},
	},
	ExecutionParameters: []*string{
		jsii.String("param1"),
		jsii.String("param2"),
	},
})
GetQueryExecution

The GetQueryExecution API gets information about a single execution of a query.

getQueryExecutionJob := tasks.NewAthenaGetQueryExecution(this, jsii.String("Get Query Execution"), &AthenaGetQueryExecutionProps{
	QueryExecutionId: sfn.JsonPath_StringAt(jsii.String("$.QueryExecutionId")),
})
GetQueryResults

The GetQueryResults API that streams the results of a single query execution specified by QueryExecutionId from S3.

getQueryResultsJob := tasks.NewAthenaGetQueryResults(this, jsii.String("Get Query Results"), &AthenaGetQueryResultsProps{
	QueryExecutionId: sfn.JsonPath_StringAt(jsii.String("$.QueryExecutionId")),
})
StopQueryExecution

The StopQueryExecution API that stops a query execution.

stopQueryExecutionJob := tasks.NewAthenaStopQueryExecution(this, jsii.String("Stop Query Execution"), &AthenaStopQueryExecutionProps{
	QueryExecutionId: sfn.JsonPath_StringAt(jsii.String("$.QueryExecutionId")),
})

Batch

Step Functions supports Batch through the service integration pattern.

SubmitJob

The SubmitJob API submits an AWS Batch job from a job definition.

import batch "github.com/aws/aws-cdk-go/awscdk"
var batchJobDefinition ecsJobDefinition
var batchQueue jobQueue


task := tasks.NewBatchSubmitJob(this, jsii.String("Submit Job"), &BatchSubmitJobProps{
	JobDefinitionArn: batchJobDefinition.JobDefinitionArn,
	JobName: jsii.String("MyJob"),
	JobQueueArn: batchQueue.JobQueueArn,
})

Bedrock

Step Functions supports Bedrock through the service integration pattern.

InvokeModel

The InvokeModel API invokes the specified Bedrock model to run inference using the input provided. The format of the input body and the response body depend on the model selected.

import "github.com/aws/aws-cdk-go/awscdk"


model := bedrock.FoundationModel_FromFoundationModelId(this, jsii.String("Model"), bedrock.FoundationModelIdentifier_AMAZON_TITAN_TEXT_G1_EXPRESS_V1())

task := tasks.NewBedrockInvokeModel(this, jsii.String("Prompt Model"), &BedrockInvokeModelProps{
	Model: Model,
	Body: sfn.TaskInput_FromObject(map[string]interface{}{
		"inputText": jsii.String("Generate a list of five first names."),
		"textGenerationConfig": map[string]*f64{
			"maxTokenCount": jsii.Number(100),
			"temperature": jsii.Number(1),
		},
	}),
	ResultSelector: map[string]interface{}{
		"names": sfn.JsonPath_stringAt(jsii.String("$.Body.results[0].outputText")),
	},
})

CodeBuild

Step Functions supports CodeBuild through the service integration pattern.

StartBuild

StartBuild starts a CodeBuild Project by Project Name.

import "github.com/aws/aws-cdk-go/awscdk"


codebuildProject := codebuild.NewProject(this, jsii.String("Project"), &ProjectProps{
	ProjectName: jsii.String("MyTestProject"),
	BuildSpec: codebuild.BuildSpec_FromObject(map[string]interface{}{
		"version": jsii.String("0.2"),
		"phases": map[string]map[string][]*string{
			"build": map[string][]*string{
				"commands": []*string{
					jsii.String("echo \"Hello, CodeBuild!\""),
				},
			},
		},
	}),
})

task := tasks.NewCodeBuildStartBuild(this, jsii.String("Task"), &CodeBuildStartBuildProps{
	Project: codebuildProject,
	IntegrationPattern: sfn.IntegrationPattern_RUN_JOB,
	EnvironmentVariablesOverride: map[string]buildEnvironmentVariable{
		"ZONE": &buildEnvironmentVariable{
			"type": codebuild.BuildEnvironmentVariableType_PLAINTEXT,
			"value": sfn.JsonPath_stringAt(jsii.String("$.envVariables.zone")),
		},
	},
})
StartBuildBatch

StartBuildBatch starts a batch CodeBuild for a project by project name. It is necessary to enable the batch build feature in the CodeBuild project.

import "github.com/aws/aws-cdk-go/awscdk"


project := codebuild.NewProject(this, jsii.String("Project"), &ProjectProps{
	ProjectName: jsii.String("MyTestProject"),
	BuildSpec: codebuild.BuildSpec_FromObjectToYaml(map[string]interface{}{
		"version": jsii.Number(0.2),

					"identifier": jsii.String("id"),
					"buildspec": jsii.String("version: 0.2\nphases:\n  build:\n    commands:\n      - echo \"Hello, from small!\""),
				},
			},
		},
	}),
})
project.EnableBatchBuilds()

task := tasks.NewCodeBuildStartBuildBatch(this, jsii.String("buildBatchTask"), &CodeBuildStartBuildBatchProps{
	Project: Project,
	IntegrationPattern: sfn.IntegrationPattern_REQUEST_RESPONSE,
	EnvironmentVariablesOverride: map[string]buildEnvironmentVariable{
		"test": &buildEnvironmentVariable{
			"type": codebuild.BuildEnvironmentVariableType_PLAINTEXT,
			"value": jsii.String("testValue"),
		},
	},
})

Note: enableBatchBuilds() will do nothing for imported projects. If you are using an imported project, you must ensure that the project is already configured for batch builds.

DynamoDB

You can call DynamoDB APIs from a Task state. Read more about calling DynamoDB APIs here

GetItem

The GetItem operation returns a set of attributes for the item with the given primary key.

var myTable table

tasks.NewDynamoGetItem(this, jsii.String("Get Item"), &DynamoGetItemProps{
	Key: map[string]dynamoAttributeValue{
		"messageId": tasks.*dynamoAttributeValue_fromString(jsii.String("message-007")),
	},
	Table: myTable,
})
PutItem

The PutItem operation creates a new item, or replaces an old item with a new item.

var myTable table

tasks.NewDynamoPutItem(this, jsii.String("PutItem"), &DynamoPutItemProps{
	Item: map[string]dynamoAttributeValue{
		"MessageId": tasks.*dynamoAttributeValue_fromString(jsii.String("message-007")),
		"Text": tasks.*dynamoAttributeValue_fromString(sfn.JsonPath_stringAt(jsii.String("$.bar"))),
		"TotalCount": tasks.*dynamoAttributeValue_fromNumber(jsii.Number(10)),
	},
	Table: myTable,
})
DeleteItem

The DeleteItem operation deletes a single item in a table by primary key.

var myTable table

tasks.NewDynamoDeleteItem(this, jsii.String("DeleteItem"), &DynamoDeleteItemProps{
	Key: map[string]dynamoAttributeValue{
		"MessageId": tasks.*dynamoAttributeValue_fromString(jsii.String("message-007")),
	},
	Table: myTable,
	ResultPath: sfn.JsonPath_DISCARD(),
})
UpdateItem

The UpdateItem operation edits an existing item's attributes, or adds a new item to the table if it does not already exist.

var myTable table

tasks.NewDynamoUpdateItem(this, jsii.String("UpdateItem"), &DynamoUpdateItemProps{
	Key: map[string]dynamoAttributeValue{
		"MessageId": tasks.*dynamoAttributeValue_fromString(jsii.String("message-007")),
	},
	Table: myTable,
	ExpressionAttributeValues: map[string]*dynamoAttributeValue{
		":val": tasks.*dynamoAttributeValue_numberFromString(sfn.JsonPath_stringAt(jsii.String("$.Item.TotalCount.N"))),
		":rand": tasks.*dynamoAttributeValue_fromNumber(jsii.Number(20)),
	},
	UpdateExpression: jsii.String("SET TotalCount = :val + :rand"),
})

ECS

Step Functions supports ECS/Fargate through the service integration pattern.

RunTask

RunTask starts a new task using the specified task definition.

EC2

The EC2 launch type allows you to run your containerized applications on a cluster of Amazon EC2 instances that you manage.

When a task that uses the EC2 launch type is launched, Amazon ECS must determine where to place the task based on the requirements specified in the task definition, such as CPU and memory. Similarly, when you scale down the task count, Amazon ECS must determine which tasks to terminate. You can apply task placement strategies and constraints to customize how Amazon ECS places and terminates tasks. Learn more about task placement

The latest ACTIVE revision of the passed task definition is used for running the task.

The following example runs a job from a task definition on EC2

vpc := ec2.Vpc_FromLookup(this, jsii.String("Vpc"), &VpcLookupOptions{
	IsDefault: jsii.Boolean(true),
})

cluster := ecs.NewCluster(this, jsii.String("Ec2Cluster"), &ClusterProps{
	Vpc: Vpc,
})
cluster.AddCapacity(jsii.String("DefaultAutoScalingGroup"), &AddCapacityOptions{
	InstanceType: ec2.NewInstanceType(jsii.String("t2.micro")),
	VpcSubnets: &SubnetSelection{
		SubnetType: ec2.SubnetType_PUBLIC,
	},
})

taskDefinition := ecs.NewTaskDefinition(this, jsii.String("TD"), &TaskDefinitionProps{
	Compatibility: ecs.Compatibility_EC2,
})

taskDefinition.AddContainer(jsii.String("TheContainer"), &ContainerDefinitionOptions{
	Image: ecs.ContainerImage_FromRegistry(jsii.String("foo/bar")),
	MemoryLimitMiB: jsii.Number(256),
})

runTask := tasks.NewEcsRunTask(this, jsii.String("Run"), &EcsRunTaskProps{
	IntegrationPattern: sfn.IntegrationPattern_RUN_JOB,
	Cluster: Cluster,
	TaskDefinition: TaskDefinition,
	LaunchTarget: tasks.NewEcsEc2LaunchTarget(&EcsEc2LaunchTargetOptions{
		PlacementStrategies: []placementStrategy{
			ecs.*placementStrategy_SpreadAcrossInstances(),
			ecs.*placementStrategy_PackedByCpu(),
			ecs.*placementStrategy_Randomly(),
		},
		PlacementConstraints: []placementConstraint{
			ecs.*placementConstraint_MemberOf(jsii.String("blieptuut")),
		},
	}),
	PropagatedTagSource: ecs.PropagatedTagSource_TASK_DEFINITION,
})
Fargate

AWS Fargate is a serverless compute engine for containers that works with Amazon Elastic Container Service (ECS). Fargate makes it easy for you to focus on building your applications. Fargate removes the need to provision and manage servers, lets you specify and pay for resources per application, and improves security through application isolation by design. Learn more about Fargate

The Fargate launch type allows you to run your containerized applications without the need to provision and manage the backend infrastructure. Just register your task definition and Fargate launches the container for you. The latest ACTIVE revision of the passed task definition is used for running the task. Learn more about Fargate Versioning

The following example runs a job from a task definition on Fargate

vpc := ec2.Vpc_FromLookup(this, jsii.String("Vpc"), &VpcLookupOptions{
	IsDefault: jsii.Boolean(true),
})

cluster := ecs.NewCluster(this, jsii.String("FargateCluster"), &ClusterProps{
	Vpc: Vpc,
})

taskDefinition := ecs.NewTaskDefinition(this, jsii.String("TD"), &TaskDefinitionProps{
	MemoryMiB: jsii.String("512"),
	Cpu: jsii.String("256"),
	Compatibility: ecs.Compatibility_FARGATE,
})

containerDefinition := taskDefinition.AddContainer(jsii.String("TheContainer"), &ContainerDefinitionOptions{
	Image: ecs.ContainerImage_FromRegistry(jsii.String("foo/bar")),
	MemoryLimitMiB: jsii.Number(256),
})

runTask := tasks.NewEcsRunTask(this, jsii.String("RunFargate"), &EcsRunTaskProps{
	IntegrationPattern: sfn.IntegrationPattern_RUN_JOB,
	Cluster: Cluster,
	TaskDefinition: TaskDefinition,
	AssignPublicIp: jsii.Boolean(true),
	ContainerOverrides: []containerOverride{
		&containerOverride{
			ContainerDefinition: *ContainerDefinition,
			Environment: []taskEnvironmentVariable{
				&taskEnvironmentVariable{
					Name: jsii.String("SOME_KEY"),
					Value: sfn.JsonPath_StringAt(jsii.String("$.SomeKey")),
				},
			},
		},
	},
	LaunchTarget: tasks.NewEcsFargateLaunchTarget(),
	PropagatedTagSource: ecs.PropagatedTagSource_TASK_DEFINITION,
})
ECS enable Exec

By setting the property enableExecuteCommand to true, you can enable the ECS Exec feature for the task for either Fargate or EC2 launch types.

vpc := ec2.Vpc_FromLookup(this, jsii.String("Vpc"), &VpcLookupOptions{
	IsDefault: jsii.Boolean(true),
})
cluster := ecs.NewCluster(this, jsii.String("ECSCluster"), &ClusterProps{
	Vpc: Vpc,
})

taskDefinition := ecs.NewTaskDefinition(this, jsii.String("TD"), &TaskDefinitionProps{
	Compatibility: ecs.Compatibility_EC2,
})

taskDefinition.AddContainer(jsii.String("TheContainer"), &ContainerDefinitionOptions{
	Image: ecs.ContainerImage_FromRegistry(jsii.String("foo/bar")),
	MemoryLimitMiB: jsii.Number(256),
})

runTask := tasks.NewEcsRunTask(this, jsii.String("Run"), &EcsRunTaskProps{
	IntegrationPattern: sfn.IntegrationPattern_RUN_JOB,
	Cluster: Cluster,
	TaskDefinition: TaskDefinition,
	LaunchTarget: tasks.NewEcsEc2LaunchTarget(),
	EnableExecuteCommand: jsii.Boolean(true),
})

EMR

Step Functions supports Amazon EMR through the service integration pattern. The service integration APIs correspond to Amazon EMR APIs but differ in the parameters that are used.

Read more about the differences when using these service integrations.

Create Cluster

Creates and starts running a cluster (job flow). Corresponds to the runJobFlow API in EMR.

clusterRole := iam.NewRole(this, jsii.String("ClusterRole"), &RoleProps{
	AssumedBy: iam.NewServicePrincipal(jsii.String("ec2.amazonaws.com")),
})

serviceRole := iam.NewRole(this, jsii.String("ServiceRole"), &RoleProps{
	AssumedBy: iam.NewServicePrincipal(jsii.String("elasticmapreduce.amazonaws.com")),
})

autoScalingRole := iam.NewRole(this, jsii.String("AutoScalingRole"), &RoleProps{
	AssumedBy: iam.NewServicePrincipal(jsii.String("elasticmapreduce.amazonaws.com")),
})

autoScalingRole.AssumeRolePolicy.AddStatements(
iam.NewPolicyStatement(&PolicyStatementProps{
	Effect: iam.Effect_ALLOW,
	Principals: []iPrincipal{
		iam.NewServicePrincipal(jsii.String("application-autoscaling.amazonaws.com")),
	},
	Actions: []*string{
		jsii.String("sts:AssumeRole"),
	},
}))

tasks.NewEmrCreateCluster(this, jsii.String("Create Cluster"), &EmrCreateClusterProps{
	Instances: &InstancesConfigProperty{
	},
	ClusterRole: ClusterRole,
	Name: sfn.TaskInput_FromJsonPathAt(jsii.String("$.ClusterName")).value,
	ServiceRole: ServiceRole,
	AutoScalingRole: AutoScalingRole,
})

You can use the launch specification for On-Demand and Spot instances in the fleet.

tasks.NewEmrCreateCluster(this, jsii.String("OnDemandSpecification"), &EmrCreateClusterProps{
	Instances: &InstancesConfigProperty{
		InstanceFleets: []instanceFleetConfigProperty{
			&instanceFleetConfigProperty{
				InstanceFleetType: tasks.EmrCreateCluster.InstanceRoleType_MASTER,
				LaunchSpecifications: &InstanceFleetProvisioningSpecificationsProperty{
					OnDemandSpecification: &OnDemandProvisioningSpecificationProperty{
						AllocationStrategy: tasks.EmrCreateCluster.OnDemandAllocationStrategy_LOWEST_PRICE,
					},
				},
			},
		},
	},
	Name: jsii.String("OnDemandCluster"),
	IntegrationPattern: sfn.IntegrationPattern_RUN_JOB,
})

tasks.NewEmrCreateCluster(this, jsii.String("SpotSpecification"), &EmrCreateClusterProps{
	Instances: &InstancesConfigProperty{
		InstanceFleets: []*instanceFleetConfigProperty{
			&instanceFleetConfigProperty{
				InstanceFleetType: tasks.EmrCreateCluster.InstanceRoleType_MASTER,
				LaunchSpecifications: &InstanceFleetProvisioningSpecificationsProperty{
					SpotSpecification: &SpotProvisioningSpecificationProperty{
						AllocationStrategy: tasks.EmrCreateCluster.SpotAllocationStrategy_CAPACITY_OPTIMIZED,
						TimeoutAction: tasks.EmrCreateCluster.SpotTimeoutAction_TERMINATE_CLUSTER,
						Timeout: awscdk.Duration_Minutes(jsii.Number(5)),
					},
				},
			},
		},
	},
	Name: jsii.String("SpotCluster"),
	IntegrationPattern: sfn.IntegrationPattern_RUN_JOB,
})

If you want to run multiple steps in parallel, you can specify the stepConcurrencyLevel property. The concurrency range is between 1 and 256 inclusive, where the default concurrency of 1 means no step concurrency is allowed. stepConcurrencyLevel requires the EMR release label to be 5.28.0 or above.

tasks.NewEmrCreateCluster(this, jsii.String("Create Cluster"), &EmrCreateClusterProps{
	Instances: &InstancesConfigProperty{
	},
	Name: sfn.TaskInput_FromJsonPathAt(jsii.String("$.ClusterName")).value,
	StepConcurrencyLevel: jsii.Number(10),
})
Termination Protection

Locks a cluster (job flow) so the EC2 instances in the cluster cannot be terminated by user intervention, an API call, or a job-flow error.

Corresponds to the setTerminationProtection API in EMR.

tasks.NewEmrSetClusterTerminationProtection(this, jsii.String("Task"), &EmrSetClusterTerminationProtectionProps{
	ClusterId: jsii.String("ClusterId"),
	TerminationProtected: jsii.Boolean(false),
})
Terminate Cluster

Shuts down a cluster (job flow). Corresponds to the terminateJobFlows API in EMR.

tasks.NewEmrTerminateCluster(this, jsii.String("Task"), &EmrTerminateClusterProps{
	ClusterId: jsii.String("ClusterId"),
})
Add Step

Adds a new step to a running cluster. Corresponds to the addJobFlowSteps API in EMR.

tasks.NewEmrAddStep(this, jsii.String("Task"), &EmrAddStepProps{
	ClusterId: jsii.String("ClusterId"),
	Name: jsii.String("StepName"),
	Jar: jsii.String("Jar"),
	ActionOnFailure: tasks.ActionOnFailure_CONTINUE,
})

To specify a custom runtime role use the executionRoleArn property.

Note: The EMR cluster must be created with a security configuration and the runtime role must have a specific trust policy. See this blog post for more details.

import emr "github.com/aws/aws-cdk-go/awscdk"


cfnSecurityConfiguration := emr.NewCfnSecurityConfiguration(this, jsii.String("EmrSecurityConfiguration"), &CfnSecurityConfigurationProps{

Corresponds to the modifyInstanceFleet API in EMR.

tasks.NewEmrModifyInstanceFleetByName(this, jsii.String("Task"), &EmrModifyInstanceFleetByNameProps{
	ClusterId: jsii.String("ClusterId"),
	InstanceFleetName: jsii.String("InstanceFleetName"),
	TargetOnDemandCapacity: jsii.Number(2),
	TargetSpotCapacity: jsii.Number(0),
})
Modify Instance Group

Modifies the number of nodes and configuration settings of an instance group.

Corresponds to the modifyInstanceGroups API in EMR.

tasks.NewEmrModifyInstanceGroupByName(this, jsii.String("Task"), &EmrModifyInstanceGroupByNameProps{
	ClusterId: jsii.String("ClusterId"),
	InstanceGroupName: sfn.JsonPath_StringAt(jsii.String("$.InstanceGroupName")),
	InstanceGroup: &InstanceGroupModifyConfigProperty{
		InstanceCount: jsii.Number(1),
	},
})

EMR on EKS

Step Functions supports Amazon EMR on EKS through the service integration pattern. The service integration APIs correspond to Amazon EMR on EKS APIs, but differ in the parameters that are used.

Read more about the differences when using these service integrations.

Setting up the EKS cluster is required.

Create Virtual Cluster

The CreateVirtualCluster API creates a single virtual cluster that's mapped to a single Kubernetes namespace.

The EKS cluster containing the Kubernetes namespace where the virtual cluster will be mapped can be passed in from the task input.

tasks.NewEmrContainersCreateVirtualCluster(this, jsii.String("Create a Virtual Cluster"), &EmrContainersCreateVirtualClusterProps{
	EksCluster: tasks.EksClusterInput_FromTaskInput(sfn.TaskInput_FromText(jsii.String("clusterId"))),
})

The EKS cluster can also be passed in directly.

import eks "github.com/aws/aws-cdk-go/awscdk"

var eksCluster cluster


tasks.NewEmrContainersCreateVirtualCluster(this, jsii.String("Create a Virtual Cluster"), &EmrContainersCreateVirtualClusterProps{
	EksCluster: tasks.EksClusterInput_FromCluster(eksCluster),
})

By default, the Kubernetes namespace that a virtual cluster maps to is "default", but a specific namespace within an EKS cluster can be selected.

tasks.NewEmrContainersCreateVirtualCluster(this, jsii.String("Create a Virtual Cluster"), &EmrContainersCreateVirtualClusterProps{
	EksCluster: tasks.EksClusterInput_FromTaskInput(sfn.TaskInput_FromText(jsii.String("clusterId"))),
	EksNamespace: jsii.String("specified-namespace"),
})
Delete Virtual Cluster

The DeleteVirtualCluster API deletes a virtual cluster.

tasks.NewEmrContainersDeleteVirtualCluster(this, jsii.String("Delete a Virtual Cluster"), &EmrContainersDeleteVirtualClusterProps{
	VirtualClusterId: sfn.TaskInput_FromJsonPathAt(jsii.String("$.virtualCluster")),
})
Start Job Run

The StartJobRun API starts a job run. A job is a unit of work that you submit to Amazon EMR on EKS for execution. The work performed by the job can be defined by a Spark jar, PySpark script, or SparkSQL query. A job run is an execution of the job on the virtual cluster.

Required setup:

The following actions must be performed if the virtual cluster ID is supplied from the task input. Otherwise, if it is supplied statically in the state machine definition, these actions will be done automatically.

The job can be configured with spark submit parameters:

tasks.NewEmrContainersStartJobRun(this, jsii.String("EMR Containers Start Job Run"), &EmrContainersStartJobRunProps{
	VirtualCluster: tasks.VirtualClusterInput_FromVirtualClusterId(jsii.String("de92jdei2910fwedz")),
	ReleaseLabel: tasks.ReleaseLabel_EMR_6_2_0(),
	JobDriver: &JobDriver{
		SparkSubmitJobDriver: &SparkSubmitJobDriver{
			EntryPoint: sfn.TaskInput_FromText(jsii.String("local:///usr/lib/spark/examples/src/main/python/pi.py")),
			SparkSubmitParameters: jsii.String("--conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"),
		},
	},
})

Configuring the job can also be done via application configuration:

tasks.NewEmrContainersStartJobRun(this, jsii.String("EMR Containers Start Job Run"), &EmrContainersStartJobRunProps{
	VirtualCluster: tasks.VirtualClusterInput_FromVirtualClusterId(jsii.String("de92jdei2910fwedz")),
	ReleaseLabel: tasks.ReleaseLabel_EMR_6_2_0(),
	JobName: jsii.String("EMR-Containers-Job"),
	JobDriver: &JobDriver{
		SparkSubmitJobDriver: &SparkSubmitJobDriver{
			EntryPoint: sfn.TaskInput_FromText(jsii.String("local:///usr/lib/spark/examples/src/main/python/pi.py")),
		},
	},
	ApplicationConfig: []applicationConfiguration{
		&applicationConfiguration{
			Classification: tasks.Classification_SPARK_DEFAULTS(),
			Properties: map[string]*string{
				"spark.executor.instances": jsii.String("1"),
				"spark.executor.memory": jsii.String("512M"),
			},
		},
	},
})

Job monitoring can be enabled if monitoring.logging is set true. This automatically generates an S3 bucket and CloudWatch logs.

tasks.NewEmrContainersStartJobRun(this, jsii.String("EMR Containers Start Job Run"), &EmrContainersStartJobRunProps{
	VirtualCluster: tasks.VirtualClusterInput_FromVirtualClusterId(jsii.String("de92jdei2910fwedz")),
	ReleaseLabel: tasks.ReleaseLabel_EMR_6_2_0(),
	JobDriver: &JobDriver{
		SparkSubmitJobDriver: &SparkSubmitJobDriver{
			EntryPoint: sfn.TaskInput_FromText(jsii.String("local:///usr/lib/spark/examples/src/main/python/pi.py")),
			SparkSubmitParameters: jsii.String("--conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"),
		},
	},
	Monitoring: &Monitoring{
		Logging: jsii.Boolean(true),
	},
})

Otherwise, providing monitoring for jobs with existing log groups and log buckets is also available.

import logs "github.com/aws/aws-cdk-go/awscdk"


logGroup := logs.NewLogGroup(this, jsii.String("Log Group"))
logBucket := s3.NewBucket(this, jsii.String("S3 Bucket"))

tasks.NewEmrContainersStartJobRun(this, jsii.String("EMR Containers Start Job Run"), &EmrContainersStartJobRunProps{
	VirtualCluster: tasks.VirtualClusterInput_FromVirtualClusterId(jsii.String("de92jdei2910fwedz")),
	ReleaseLabel: tasks.ReleaseLabel_EMR_6_2_0(),
	JobDriver: &JobDriver{
		SparkSubmitJobDriver: &SparkSubmitJobDriver{
			EntryPoint: sfn.TaskInput_FromText(jsii.String("local:///usr/lib/spark/examples/src/main/python/pi.py")),
			SparkSubmitParameters: jsii.String("--conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"),
		},
	},
	Monitoring: &Monitoring{
		LogGroup: logGroup,
		LogBucket: logBucket,
	},
})

Users can provide their own existing Job Execution Role.

tasks.NewEmrContainersStartJobRun(this, jsii.String("EMR Containers Start Job Run"), &EmrContainersStartJobRunProps{
	VirtualCluster: tasks.VirtualClusterInput_FromTaskInput(sfn.TaskInput_FromJsonPathAt(jsii.String("$.VirtualClusterId"))),
	ReleaseLabel: tasks.ReleaseLabel_EMR_6_2_0(),
	JobName: jsii.String("EMR-Containers-Job"),
	ExecutionRole: iam.Role_FromRoleArn(this, jsii.String("Job-Execution-Role"), jsii.String("arn:aws:iam::xxxxxxxxxxxx:role/JobExecutionRole")),
	JobDriver: &JobDriver{
		SparkSubmitJobDriver: &SparkSubmitJobDriver{
			EntryPoint: sfn.TaskInput_FromText(jsii.String("local:///usr/lib/spark/examples/src/main/python/pi.py")),
			SparkSubmitParameters: jsii.String("--conf spark.executor.instances=2 --conf spark.executor.memory=2G --conf spark.executor.cores=2 --conf spark.driver.cores=1"),
		},
	},
})

EKS

Step Functions supports Amazon EKS through the service integration pattern. The service integration APIs correspond to Amazon EKS APIs.

Read more about the differences when using these service integrations.

Call

Read and write Kubernetes resource objects via a Kubernetes API endpoint. Corresponds to the call API in Step Functions Connector.

The following code snippet includes a Task state that uses eks:call to list the pods.

import "github.com/aws/aws-cdk-go/awscdk"


myEksCluster := eks.NewCluster(this, jsii.String("my sample cluster"), &ClusterProps{
	Version: eks.KubernetesVersion_V1_18(),
	ClusterName: jsii.String("myEksCluster"),
})

tasks.NewEksCall(this, jsii.String("Call a EKS Endpoint"), &EksCallProps{
	Cluster: myEksCluster,
	HttpMethod: tasks.HttpMethods_GET,
	HttpPath: jsii.String("/api/v1/namespaces/default/pods"),
})

EventBridge

Step Functions supports Amazon EventBridge through the service integration pattern. The service integration APIs correspond to Amazon EventBridge APIs.

Read more about the differences when using these service integrations.

Put Events

Send events to an EventBridge bus. Corresponds to the put-events API in Step Functions Connector.

The following code snippet includes a Task state that uses events:putevents to send an event to the default bus.

import events "github.com/aws/aws-cdk-go/awscdk"


myEventBus := events.NewEventBus(this, jsii.String("EventBus"), &EventBusProps{
	EventBusName: jsii.String("MyEventBus1"),
})

tasks.NewEventBridgePutEvents(this, jsii.String("Send an event to EventBridge"), &EventBridgePutEventsProps{
	Entries: []eventBridgePutEventsEntry{
		&eventBridgePutEventsEntry{
			Detail: sfn.TaskInput_FromObject(map[string]interface{}{
				"Message": jsii.String("Hello from Step Functions!"),
			}),
			EventBus: myEventBus,
			DetailType: jsii.String("MessageFromStepFunctions"),
			Source: jsii.String("step.functions"),
		},
	},
})

Glue

Step Functions supports AWS Glue through the service integration pattern.

StartJobRun

You can call the StartJobRun API from a Task state.

tasks.NewGlueStartJobRun(this, jsii.String("Task"), &GlueStartJobRunProps{
	GlueJobName: jsii.String("my-glue-job"),
	Arguments: sfn.TaskInput_FromObject(map[string]interface{}{
		"key": jsii.String("value"),
	}),
	TaskTimeout: sfn.Timeout_Duration(awscdk.Duration_Minutes(jsii.Number(30))),
	NotifyDelayAfter: awscdk.Duration_*Minutes(jsii.Number(5)),
})
StartCrawlerRun

You can call the StartCrawler API from a Task state through AWS SDK service integrations.

import glue "github.com/aws/aws-cdk-go/awscdk"

var myCrawler cfnCrawler


// You can get the crawler name from `crawler.ref`
// You can get the crawler name from `crawler.ref`
tasks.NewGlueStartCrawlerRun(this, jsii.String("Task1"), &GlueStartCrawlerRunProps{
	CrawlerName: myCrawler.ref,
})

// Of course, you can also specify the crawler name directly.
// Of course, you can also specify the crawler name directly.
tasks.NewGlueStartCrawlerRun(this, jsii.String("Task2"), &GlueStartCrawlerRunProps{
	CrawlerName: jsii.String("my-crawler-job"),
})

Glue DataBrew

Step Functions supports AWS Glue DataBrew through the service integration pattern.

Start Job Run

You can call the StartJobRun API from a Task state.

tasks.NewGlueDataBrewStartJobRun(this, jsii.String("Task"), &GlueDataBrewStartJobRunProps{
	Name: jsii.String("databrew-job"),
})

Invoke HTTP API

Step Functions supports calling third-party APIs with credentials managed by Amazon EventBridge Connections.

The following snippet creates a new API destination connection, and uses it to make a POST request to the specified URL. The endpoint response is available at the $.ResponseBody path.

import "github.com/aws/aws-cdk-go/awscdk"


connection := events.NewConnection(this, jsii.String("Connection"), &ConnectionProps{
	Authorization: events.Authorization_Basic(jsii.String("username"), awscdk.SecretValue_UnsafePlainText(jsii.String("password"))),
})

tasks.NewHttpInvoke(this, jsii.String("Invoke HTTP API"), &HttpInvokeProps{
	ApiRoot: jsii.String("https://api.example.com"),
	ApiEndpoint: sfn.TaskInput_FromText(jsii.String("https://api.example.com/path/to/resource")),
	Body: sfn.TaskInput_FromObject(map[string]interface{}{
		"foo": jsii.String("bar"),
	}),
	Connection: Connection,
	Headers: sfn.TaskInput_*FromObject(map[string]interface{}{
		"Content-Type": jsii.String("application/json"),
	}),
	Method: sfn.TaskInput_*FromText(jsii.String("POST")),
	QueryStringParameters: sfn.TaskInput_*FromObject(map[string]interface{}{
		"id": jsii.String("123"),
	}),
	UrlEncodingFormat: tasks.URLEncodingFormat_BRACKETS,
})

Lambda

Step Functions supports AWS Lambda through the service integration pattern.

Invoke

Invoke a Lambda function.

You can specify the input to your Lambda function through the payload attribute. By default, Step Functions invokes Lambda function with the state input (JSON path '$') as the input.

The following snippet invokes a Lambda Function with the state input as the payload by referencing the $ path.

var fn function

tasks.NewLambdaInvoke(this, jsii.String("Invoke with state input"), &LambdaInvokeProps{
	LambdaFunction: fn,
})

When a function is invoked, the Lambda service sends these response elements back.

⚠️ The response from the Lambda function is in an attribute called Payload

The following snippet invokes a Lambda Function by referencing the $.Payload path to reference the output of a Lambda executed before it.

var fn function

tasks.NewLambdaInvoke(this, jsii.String("Invoke with empty object as payload"), &LambdaInvokeProps{
	LambdaFunction: fn,
	Payload: sfn.TaskInput_FromObject(map[string]interface{}{
	}),
})

// use the output of fn as input
// use the output of fn as input
tasks.NewLambdaInvoke(this, jsii.String("Invoke with payload field in the state input"), &LambdaInvokeProps{
	LambdaFunction: fn,
	Payload: sfn.TaskInput_FromJsonPathAt(jsii.String("$.Payload")),
})

The following snippet invokes a Lambda and sets the task output to only include the Lambda function response.

var fn function

tasks.NewLambdaInvoke(this, jsii.String("Invoke and set function response as task output"), &LambdaInvokeProps{
	LambdaFunction: fn,
	OutputPath: jsii.String("$.Payload"),
})

If you want to combine the input and the Lambda function response you can use the payloadResponseOnly property and specify the resultPath. This will put the Lambda function ARN directly in the "Resource" string, but it conflicts with the integrationPattern, invocationType, clientContext, and qualifier properties.

var fn function

tasks.NewLambdaInvoke(this, jsii.String("Invoke and combine function response with task input"), &LambdaInvokeProps{
	LambdaFunction: fn,
	PayloadResponseOnly: jsii.Boolean(true),
	ResultPath: jsii.String("$.fn"),
})

You can have Step Functions pause a task, and wait for an external process to return a task token. Read more about the callback pattern

To use the callback pattern, set the token property on the task. Call the Step Functions SendTaskSuccess or SendTaskFailure APIs with the token to indicate that the task has completed and the state machine should resume execution.

The following snippet invokes a Lambda with the task token as part of the input to the Lambda.

var fn function

tasks.NewLambdaInvoke(this, jsii.String("Invoke with callback"), &LambdaInvokeProps{
	LambdaFunction: fn,
	IntegrationPattern: sfn.IntegrationPattern_WAIT_FOR_TASK_TOKEN,
	Payload: sfn.TaskInput_FromObject(map[string]interface{}{
		"token": sfn.JsonPath_taskToken(),
		"input": sfn.JsonPath_stringAt(jsii.String("$.someField")),
	}),
})

⚠️ The task will pause until it receives that task token back with a SendTaskSuccess or SendTaskFailure call. Learn more about Callback with the Task Token.

AWS Lambda can occasionally experience transient service errors. In this case, invoking Lambda results in a 500 error, such as ClientExecutionTimeoutException, ServiceException, AWSLambdaException, or SdkClientException. As a best practice, the LambdaInvoke task will retry on those errors with an interval of 2 seconds, a back-off rate of 2 and 6 maximum attempts. Set the retryOnServiceExceptions prop to false to disable this behavior.

SageMaker

Step Functions supports AWS SageMaker through the service integration pattern.

If your training job or model uses resources from AWS Marketplace, network isolation is required. To do so, set the enableNetworkIsolation property to true for SageMakerCreateModel or SageMakerCreateTrainingJob.

To set environment variables for the Docker container use the environment property.

Create Training Job

You can call the CreateTrainingJob API from a Task state.

tasks.NewSageMakerCreateTrainingJob(this, jsii.String("TrainSagemaker"), &SageMakerCreateTrainingJobProps{
	TrainingJobName: sfn.JsonPath_StringAt(jsii.String("$.JobName")),
	AlgorithmSpecification: &AlgorithmSpecification{
		AlgorithmName: jsii.String("BlazingText"),
		TrainingInputMode: tasks.InputMode_FILE,
	},
	InputDataConfig: []channel{
		&channel{
			ChannelName: jsii.String("train"),
			DataSource: &DataSource{
				S3DataSource: &S3DataSource{
					S3DataType: tasks.S3DataType_S3_PREFIX,
					S3Location: tasks.S3Location_FromJsonExpression(jsii.String("$.S3Bucket")),
				},
			},
		},
	},
	OutputDataConfig: &OutputDataConfig{
		S3OutputLocation: tasks.S3Location_FromBucket(s3.Bucket_FromBucketName(this, jsii.String("Bucket"), jsii.String("mybucket")), jsii.String("myoutputpath")),
	},
	ResourceConfig: &ResourceConfig{
		InstanceCount: jsii.Number(1),
		InstanceType: ec2.NewInstanceType(sfn.JsonPath_*StringAt(jsii.String("$.InstanceType"))),
		VolumeSize: awscdk.Size_Gibibytes(jsii.Number(50)),
	},
	 // optional: default is 1 instance of EC2 `M4.XLarge` with `10GB` volume
	StoppingCondition: &StoppingCondition{
		MaxRuntime: awscdk.Duration_Hours(jsii.Number(2)),
	},
})

You can specify TrainingInputMode via the trainingInputMode property.

  • To download the data from Amazon Simple Storage Service (Amazon S3) to the provisioned ML storage volume, and mount the directory to a Docker volume, choose InputMode.FILE if an algorithm supports it.
  • To stream data directly from Amazon S3 to the container, choose InputMode.PIPE if an algorithm supports it.
  • To stream data directly from Amazon S3 to the container with no code changes and to provide file system access to the data, choose InputMode.FAST_FILE if an algorithm supports it.
Create Transform Job

You can call the CreateTransformJob API from a Task state.

tasks.NewSageMakerCreateTransformJob(this, jsii.String("Batch Inference"), &SageMakerCreateTransformJobProps{
	TransformJobName: jsii.String("MyTransformJob"),
	ModelName: jsii.String("MyModelName"),
	ModelClientOptions: &ModelClientOptions{
		InvocationsMaxRetries: jsii.Number(3),
		 // default is 0
		InvocationsTimeout: awscdk.Duration_Minutes(jsii.Number(5)),
	},
	TransformInput: &TransformInput{
		TransformDataSource: &TransformDataSource{
			S3DataSource: &TransformS3DataSource{
				S3Uri: jsii.String("s3://inputbucket/train"),
				S3DataType: tasks.S3DataType_S3_PREFIX,
			},
		},
	},
	TransformOutput: &TransformOutput{
		S3OutputPath: jsii.String("s3://outputbucket/TransformJobOutputPath"),
	},
	TransformResources: &TransformResources{
		InstanceCount: jsii.Number(1),
		InstanceType: ec2.InstanceType_Of(ec2.InstanceClass_M4, ec2.InstanceSize_XLARGE),
	},
})
Create Endpoint

You can call the CreateEndpoint API from a Task state.

tasks.NewSageMakerCreateEndpoint(this, jsii.String("SagemakerEndpoint"), &SageMakerCreateEndpointProps{
	EndpointName: sfn.JsonPath_StringAt(jsii.String("$.EndpointName")),
	EndpointConfigName: sfn.JsonPath_*StringAt(jsii.String("$.EndpointConfigName")),
})
Create Endpoint Config

You can call the CreateEndpointConfig API from a Task state.

tasks.NewSageMakerCreateEndpointConfig(this, jsii.String("SagemakerEndpointConfig"), &SageMakerCreateEndpointConfigProps{
	EndpointConfigName: jsii.String("MyEndpointConfig"),
	ProductionVariants: []productionVariant{
		&productionVariant{
			InitialInstanceCount: jsii.Number(2),
			InstanceType: ec2.InstanceType_Of(ec2.InstanceClass_M5, ec2.InstanceSize_XLARGE),
			ModelName: jsii.String("MyModel"),
			VariantName: jsii.String("awesome-variant"),
		},
	},
})
Create Model

You can call the CreateModel API from a Task state.

tasks.NewSageMakerCreateModel(this, jsii.String("Sagemaker"), &SageMakerCreateModelProps{
	ModelName: jsii.String("MyModel"),
	PrimaryContainer: tasks.NewContainerDefinition(&ContainerDefinitionOptions{
		Image: tasks.DockerImage_FromJsonExpression(sfn.JsonPath_StringAt(jsii.String("$.Model.imageName"))),
		Mode: tasks.Mode_SINGLE_MODEL,
		ModelS3Location: tasks.S3Location_FromJsonExpression(jsii.String("$.TrainingJob.ModelArtifacts.S3ModelArtifacts")),
	}),
})
Update Endpoint

You can call the UpdateEndpoint API from a Task state.

tasks.NewSageMakerUpdateEndpoint(this, jsii.String("SagemakerEndpoint"), &SageMakerUpdateEndpointProps{
	EndpointName: sfn.JsonPath_StringAt(jsii.String("$.Endpoint.Name")),
	EndpointConfigName: sfn.JsonPath_*StringAt(jsii.String("$.Endpoint.EndpointConfig")),
})

SNS

Step Functions supports Amazon SNS through the service integration pattern.

Publish

You can call the Publish API from a Task state to publish to an SNS topic.

topic := sns.NewTopic(this, jsii.String("Topic"))

// Use a field from the execution data as message.
task1 := tasks.NewSnsPublish(this, jsii.String("Publish1"), &SnsPublishProps{
	Topic: Topic,
	IntegrationPattern: sfn.IntegrationPattern_REQUEST_RESPONSE,
	Message: sfn.TaskInput_FromDataAt(jsii.String("$.state.message")),
	MessageAttributes: map[string]messageAttribute{
		"place": &messageAttribute{
			"value": sfn.JsonPath_stringAt(jsii.String("$.place")),
		},
		"pic": &messageAttribute{
			// BINARY must be explicitly set
			"dataType": tasks.MessageAttributeDataType_BINARY,
			"value": sfn.JsonPath_stringAt(jsii.String("$.pic")),
		},
		"people": &messageAttribute{
			"value": jsii.Number(4),
		},
		"handles": &messageAttribute{
			"value": []interface{}{
				jsii.String("@kslater"),
				jsii.String("@jjf"),
				nil,
				jsii.String("@mfanning"),
			},
		},
	},
})

// Combine a field from the execution data with
// a literal object.
task2 := tasks.NewSnsPublish(this, jsii.String("Publish2"), &SnsPublishProps{
	Topic: Topic,
	Message: sfn.TaskInput_FromObject(map[string]interface{}{
		"field1": jsii.String("somedata"),
		"field2": sfn.JsonPath_stringAt(jsii.String("$.field2")),
	}),
})

Step Functions

Step Functions supports AWS Step Functions through the service integration pattern.

Start Execution

You can manage AWS Step Functions executions.

AWS Step Functions supports it's own StartExecution API as a service integration.

// Define a state machine with one Pass state
child := sfn.NewStateMachine(this, jsii.String("ChildStateMachine"), &StateMachineProps{
	Definition: sfn.Chain_Start(sfn.NewPass(this, jsii.String("PassState"))),
})

// Include the state machine in a Task state with callback pattern
task := tasks.NewStepFunctionsStartExecution(this, jsii.String("ChildTask"), &StepFunctionsStartExecutionProps{
	StateMachine: child,
	IntegrationPattern: sfn.IntegrationPattern_WAIT_FOR_TASK_TOKEN,
	Input: sfn.TaskInput_FromObject(map[string]interface{}{
		"token": sfn.JsonPath_taskToken(),
		"foo": jsii.String("bar"),
	}),
	Name: jsii.String("MyExecutionName"),
})

// Define a second state machine with the Task state above
// Define a second state machine with the Task state above
sfn.NewStateMachine(this, jsii.String("ParentStateMachine"), &StateMachineProps{
	Definition: task,
})

You can utilize Associate Workflow Executions via the associateWithParent property. This allows the Step Functions UI to link child executions from parent executions, making it easier to trace execution flow across state machines.

var child stateMachine

task := tasks.NewStepFunctionsStartExecution(this, jsii.String("ChildTask"), &StepFunctionsStartExecutionProps{
	StateMachine: child,
	AssociateWithParent: jsii.Boolean(true),
})

This will add the payload AWS_STEP_FUNCTIONS_STARTED_BY_EXECUTION_ID.$: $$.Execution.Id to the inputproperty for you, which will pass the execution ID from the context object to the execution input. It requires input to be an object or not be set at all.

Invoke Activity

You can invoke a Step Functions Activity which enables you to have a task in your state machine where the work is performed by a worker that can be hosted on Amazon EC2, Amazon ECS, AWS Lambda, basically anywhere. Activities are a way to associate code running somewhere (known as an activity worker) with a specific task in a state machine.

When Step Functions reaches an activity task state, the workflow waits for an activity worker to poll for a task. An activity worker polls Step Functions by using GetActivityTask, and sending the ARN for the related activity.

After the activity worker completes its work, it can provide a report of its success or failure by using SendTaskSuccess or SendTaskFailure. These two calls use the taskToken provided by GetActivityTask to associate the result with that task.

The following example creates an activity and creates a task that invokes the activity.

submitJobActivity := sfn.NewActivity(this, jsii.String("SubmitJob"))

tasks.NewStepFunctionsInvokeActivity(this, jsii.String("Submit Job"), &StepFunctionsInvokeActivityProps{
	Activity: submitJobActivity,
})

Use the Parameters field to create a collection of key-value pairs that are passed as input. The values of each can either be static values that you include in your state machine definition, or selected from either the input or the context object with a path.

submitJobActivity := sfn.NewActivity(this, jsii.String("SubmitJob"))

tasks.NewStepFunctionsInvokeActivity(this, jsii.String("Submit Job"), &StepFunctionsInvokeActivityProps{
	Activity: submitJobActivity,
	Parameters: map[string]interface{}{
		"comment": jsii.String("Selecting what I care about."),
		"MyDetails": map[string]interface{}{
			"size": sfn.JsonPath_stringAt(jsii.String("$.product.details.size")),
			"exists": sfn.JsonPath_stringAt(jsii.String("$.product.availability")),
			"StaticValue": jsii.String("foo"),
		},
	},
})

SQS

Step Functions supports Amazon SQS

Send Message

You can call the SendMessage API from a Task state to send a message to an SQS queue.

queue := sqs.NewQueue(this, jsii.String("Queue"))

// Use a field from the execution data as message.
task1 := tasks.NewSqsSendMessage(this, jsii.String("Send1"), &SqsSendMessageProps{
	Queue: Queue,
	MessageBody: sfn.TaskInput_FromJsonPathAt(jsii.String("$.message")),
})

// Combine a field from the execution data with
// a literal object.
task2 := tasks.NewSqsSendMessage(this, jsii.String("Send2"), &SqsSendMessageProps{
	Queue: Queue,
	MessageBody: sfn.TaskInput_FromObject(map[string]interface{}{
		"field1": jsii.String("somedata"),
		"field2": sfn.JsonPath_stringAt(jsii.String("$.field2")),
	}),
})

Functions

func AthenaGetQueryExecution_FilterNextables 

func AthenaGetQueryExecution_FilterNextables(states *[]awsstepfunctions.State) *[]awsstepfunctions.INextable

Return only the states that allow chaining from an array of states.

func AthenaGetQueryExecution_FindReachableEndStates 

func AthenaGetQueryExecution_FindReachableEndStates(start awsstepfunctions.State, options *awsstepfunctions.FindStateOptions) *[]awsstepfunctions.State

Find the set of end states states reachable through transitions from the given start state.

func AthenaGetQueryExecution_FindReachableStates 

func AthenaGetQueryExecution_FindReachableStates(start awsstepfunctions.State, options *awsstepfunctions.FindStateOptions) *[]awsstepfunctions.State

Find the set of states reachable through transitions from the given start state.

This does not retrieve states from within sub-graphs, such as states within a Parallel state's branch.

func AthenaGetQueryExecution_IsConstruct 

func AthenaGetQueryExecution_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

Find the set of states reachable through transitions from the given start state.

This does not retrieve states from within sub-graphs, such as states within a Parallel state's branch.

func EksCall_IsConstruct 

func EksCall_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

Returns: true if `x` is an object created from a class which extends `Construct`.

func StepFunctionsInvokeActivity_PrefixStates 

func StepFunctionsInvokeActivity_PrefixStates(root constructs.IConstruct, prefix *string)

Add a prefix to the stateId of all States found in a construct tree.

func StepFunctionsStartExecution_FilterNextables 

func StepFunctionsStartExecution_FilterNextables(states *[]awsstepfunctions.State) *[]awsstepfunctions.INextable

Return only the states that allow chaining from an array of states.

func StepFunctionsStartExecution_FindReachableEndStates 

func StepFunctionsStartExecution_FindReachableEndStates(start awsstepfunctions.State, options *awsstepfunctions.FindStateOptions) *[]awsstepfunctions.State

Find the set of end states states reachable through transitions from the given start state.

func StepFunctionsStartExecution_FindReachableStates 

func StepFunctionsStartExecution_FindReachableStates(start awsstepfunctions.State, options *awsstepfunctions.FindStateOptions) *[]awsstepfunctions.State

Find the set of states reachable through transitions from the given start state.

This does not retrieve states from within sub-graphs, such as states within a Parallel state's branch.

func StepFunctionsStartExecution_IsConstruct 

func StepFunctionsStartExecution_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

func StepFunctionsStartExecution_PrefixStates 

func StepFunctionsStartExecution_PrefixStates(root constructs.IConstruct, prefix *string)

Add a prefix to the stateId of all States found in a construct tree.

Call REST API endpoint as a Task.

Be aware that the header values must be arrays. When passing the Task Token in the headers field `WAIT_FOR_TASK_TOKEN` integration, use `JsonPath.array()` to wrap the token in an array:

```ts import * as apigateway from 'aws-cdk-lib/aws-apigateway'; declare const api: apigateway.RestApi; 

new tasks.CallApiGatewayRestApiEndpoint(this, 'Endpoint', {
  api,
  stageName: 'Stage',
  method: tasks.HttpMethod.PUT,
  integrationPattern: sfn.IntegrationPattern.WAIT_FOR_TASK_TOKEN,
  headers: sfn.TaskInput.fromObject({
    TaskToken: sfn.JsonPath.array(sfn.JsonPath.taskToken),
  }),
});

```.

Example: 

import apigateway "github.com/aws/aws-cdk-go/awscdk"
var api restApi

tasks.NewCallApiGatewayRestApiEndpoint(this, jsii.String("Endpoint"), &CallApiGatewayRestApiEndpointProps{

Starts a job run.

A job is a unit of work that you submit to Amazon EMR on EKS for execution. The work performed by the job can be defined by a Spark jar, PySpark script, or SparkSQL query. A job run is an execution of the job on the virtual cluster.

Example: 

tasks.NewEmrContainersStartJobRun(this, jsii.String("EMR Containers Start Job Run"), &EmrContainersStartJobRunProps{
	VirtualCluster: tasks.VirtualClusterInput_FromVirtualClusterId(jsii.String("de92jdei2910fwedz")),
