Amazon EventBridge Scheduler Construct Library
---


The APIs of higher level constructs in this module are experimental and under active development.
They are subject to non-backward compatible changes or removal in any future version. These are
not subject to the Semantic Versioning model and breaking changes will be
announced in the release notes. This means that while you may use them, you may need to update
your source code when upgrading to a newer version of this package.



Amazon EventBridge Scheduler is a feature from Amazon EventBridge
that allows you to create, run, and manage scheduled tasks at scale. With EventBridge Scheduler, you can schedule one-time or recurrently tens
of millions of tasks across many AWS services without provisioning or managing underlying infrastructure.
This library contains integration classes for Amazon EventBridge Scheduler to call any
number of supported AWS Services.
The following targets are supported:

targets.LambdaInvoke: Invoke an AWS Lambda function)
targets.StepFunctionsStartExecution: Start an AWS Step Function
targets.CodeBuildStartBuild: Start a CodeBuild job
targets.SqsSendMessage: Send a Message to an Amazon SQS Queue
targets.SnsPublish: Publish messages to an Amazon SNS topic
targets.EventBridgePutEvents: Put Events on EventBridge
targets.InspectorStartAssessmentRun: Start an Amazon Inspector assessment run
targets.KinesisStreamPutRecord: Put a record to an Amazon Kinesis Data Streams
targets.KinesisDataFirehosePutRecord: Put a record to a Kinesis Data Firehose
targets.CodePipelineStartPipelineExecution: Start a CodePipeline execution
targets.SageMakerStartPipelineExecution: Start a SageMaker pipeline execution

Invoke a Lambda function
Use the LambdaInvoke target to invoke a lambda function.
The code snippet below creates an event rule with a Lambda function as a target
called every hour by Event Bridge Scheduler with custom payload. You can optionally attach a
dead letter queue.
import aws_cdk.aws_lambda as lambda_


fn = lambda_.Function(self, "MyFunc",
runtime=lambda_.Runtime.NODEJS_LATEST,
handler="index.handler",
code=lambda_.Code.from_inline("exports.handler = handler.toString()")
)

dlq = sqs.Queue(self, "DLQ",
queue_name="MyDLQ"
)

target = targets.LambdaInvoke(fn,
dead_letter_queue=dlq,
max_event_age=Duration.minutes(1),
retry_attempts=3,
input=ScheduleTargetInput.from_object({
"payload": "useful"
})
)

schedule = Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.hours(1)),
target=target
)

Start an AWS Step Function
Use the StepFunctionsStartExecution target to start a new execution on a StepFunction.
The code snippet below creates an event rule with a Step Function as a target
called every hour by Event Bridge Scheduler with a custom payload.
import aws_cdk.aws_stepfunctions as sfn
import aws_cdk.aws_stepfunctions_tasks as tasks


payload = {
"Name": "MyParameter",
"Value": "🌥️"
}

put_parameter_step = tasks.CallAwsService(self, "PutParameter",
service="ssm",
action="putParameter",
iam_resources=["*"],
parameters={
"Name.$": "$.Name",
"Value.$": "$.Value",
"Type": "String",
"Overwrite": True
}
)

state_machine = sfn.StateMachine(self, "StateMachine",
definition_body=sfn.DefinitionBody.from_chainable(put_parameter_step)
)

Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.hours(1)),
target=targets.StepFunctionsStartExecution(state_machine,
input=ScheduleTargetInput.from_object(payload)
)
)

Start a CodeBuild job
Use the CodeBuildStartBuild target to start a new build run on a CodeBuild project.
The code snippet below creates an event rule with a CodeBuild project as target which is
called every hour by Event Bridge Scheduler.
import aws_cdk.aws_codebuild as codebuild

# project: codebuild.Project


Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.minutes(60)),
target=targets.CodeBuildStartBuild(project)
)

Send A Message To SQS Queue
Use the SqsSendMessage target to send a message to SQS Queue.
The code snippet below creates an event rule with a SQS Queue as a target
called every hour by Event Bridge Scheduler with a custom payload.
Contains the messageGroupId to use when the target is a FIFO queue. If you specify
a FIFO queue as a target, the queue must have content-based deduplication enabled.
payload = "test"
message_group_id = "id"
queue = sqs.Queue(self, "MyQueue",
fifo=True,
content_based_deduplication=True
)

target = targets.SqsSendMessage(queue,
input=ScheduleTargetInput.from_text(payload),
message_group_id=message_group_id
)

Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.minutes(1)),
target=target
)

Publish messages to an Amazon SNS topic
Use the SnsPublish target to publish messages to an Amazon SNS topic.
The code snippets below create an event rule with a Amazon SNS topic as a target.
It's called every hour by Amazon Event Bridge Scheduler with custom payload.
import aws_cdk.aws_sns as sns


topic = sns.Topic(self, "Topic")

payload = {
"message": "Hello scheduler!"
}

target = targets.SnsPublish(topic,
input=ScheduleTargetInput.from_object(payload)
)

Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.hours(1)),
target=target
)

Send events to an EventBridge event bus
Use the EventBridgePutEvents target to send events to an EventBridge event bus.
The code snippet below creates an event rule with an EventBridge event bus as a target
called every hour by Event Bridge Scheduler with a custom event payload.
import aws_cdk.aws_events as events


event_bus = events.EventBus(self, "EventBus",
event_bus_name="DomainEvents"
)

event_entry = targets.EventBridgePutEventsEntry(
event_bus=event_bus,
source="PetService",
detail=ScheduleTargetInput.from_object({"Name": "Fluffy"}),
detail_type="🐶"
)

Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.hours(1)),
target=targets.EventBridgePutEvents(event_entry)
)

Start an Amazon Inspector assessment run
Use the InspectorStartAssessmentRun target to start an Inspector assessment run.
The code snippet below creates an event rule with an assessment template as target which is
called every hour by Event Bridge Scheduler.
import aws_cdk.aws_inspector as inspector

# assessment_template: inspector.CfnAssessmentTemplate


Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.minutes(60)),
target=targets.InspectorStartAssessmentRun(assessment_template)
)

Put a record to an Amazon Kinesis Data Streams
Use the KinesisStreamPutRecord target to put a record to an Amazon Kinesis Data Streams.
The code snippet below creates an event rule with a stream as target which is
called every hour by Event Bridge Scheduler.
import aws_cdk.aws_kinesis as kinesis


stream = kinesis.Stream(self, "MyStream")

Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.minutes(60)),
target=targets.KinesisStreamPutRecord(stream,
partition_key="key"
)
)

Put a record to a Kinesis Data Firehose
Use the KinesisDataFirehosePutRecord target to put a record to a Kinesis Data Firehose delivery stream.
The code snippet below creates an event rule with a delivery stream as a target
called every hour by Event Bridge Scheduler with a custom payload.
import aws_cdk.aws_kinesisfirehose as firehose
# delivery_stream: firehose.CfnDeliveryStream


payload = {
"Data": "record"
}

Schedule(self, "Schedule",
schedule=ScheduleExpression.rate(Duration.minutes(60)),
target=targets.KinesisDataFirehosePutRecord(delivery_stream,
input=ScheduleTargetInput.from_object(payload)
)
)

Start a CodePipeline execution
Use the CodePipelineStartPipelineExecution target to start a new execution for a CodePipeline pipeline.
