问题 From this page: https://docs.aws.amazon.com/step-functions/latest/dg/input-output-contextobject.html I'm using "TransformJobName.$": "$$.Execution.Name" to define a dynamic SageMaker job name since the name needs to be unique otherwise statemachine will fail When I executed the statemachine, I got the error below: { "resourceType": "sagemaker", "resource": "createTransformJob.sync", "error": "SageMaker.AmazonSageMakerException", "cause": "2 validation errors detected: Value '808bxx-xxxx-xxxx

问题 I'm newbie to AWS Step Functions and AWS Batch. I'm trying to integrate AWS Batch Job with Step Function. AWS Batch Job executes simple python scripts which output string value (High level simplified requirement) . I need to have the python script output available to the next state of the step function. How I should be able to accomplish this. AWS Batch Job output does not contain results of the python script. instead it contains all the container related information with input values.

问题 I accidentally started very many step functions and now wish to terminate all of them. Any smart ways to do this using the CLI or web console? 回答1: OK, let's do this using the CLI. You can stop an execution using the following: aws stepfunctions stop-execution \ --execution-arn <STEP FUNCTION EXECUTION ARN> But since I started way too many executions, it's helpful to be able to list all running executions of a state machine: aws stepfunctions list-executions \ --state-machine-arn <STEP

问题 AWS Step Functions may be run in a local Docker environment using Step Functions Local Docker. However, the step functions need to be defined using the JSON-based Amazon States Language. This is not at all convenient if your AWS infrastructure (Step Functions plus lambdas) is defined using AWS CDK/CloudFormation. Is there a way to create the Amazon States Language definition of a state machine from the CDK or CloudFormation output, such that it’s possible to run the step functions locally? My

问题 I have a step function statemachine which creates SageMaker batch transform job, the definition is written in Terraform, I wanted to add the stepfunction execution id to the batch transform job names: in stepfunction terraform file: definition = templatefile("stepfuntion.json", { xxxx ) in the "stepfuntion.json": {... "TransformJobName": "jobname-$$.Execution.Id", } }, "End": true } } } But after terraform apply, it didn't generate the actual id, it gave me jobname-$$.Execution.Id , can

问题 Is it possible to have following kind of Step Function graph, i.e. from 2 parallel state output, one combined state: If yes, what would json for this looks like? If not, why? 回答1: It is possible as opposed diagram below The parallel state should look like this "MyParallelState": { "Type": "Parallel", "InputPath": "$", "OutputPath": "$", "ResultPath": "$.ParallelResultPath", "Next": "SetCartCompleteStatusState", "Branches": [ { "StartAt": "UpdateMonthlyUsageState", "States": {

问题 So timers are durable in workflow engines like Cadence, SWF and Step functions. Durable timer is useful for use cases that need to wait for a long period of time, then wake up to execute some business logic. Because of the durability, it’s resilient to various failures, making the programming experience and model much better for developers. But what if you want to change a timer after it has started? Like this example: @Override public void sampleWorkflowWithTimer(Input input){ //... //some
