Package: aws-solutions-constructs.aws-s3-step-function
aws-s3-step-function module---Some of our early constructs don’t meet the naming standards that evolved for the library. We are releasing completely feature compatible versions with corrected names. The underlying implementation code is the same regardless of whether you deploy the construct using the old or new name. We will support both names for all 1.x releases, but in 2.x we will only publish the correctly named constructs. This construct is being replaced by the functionally identical aws-s3-stepfunctions.Reference Documentation:https://docs.aws.amazon.com/solutions/latest/constructs/LanguagePackagePythonaws_solutions_constructs.aws_s3_step_functionTypescript@aws-solutions-constructs/aws-s3-step-functionJavasoftware.amazon.awsconstructs.services.s3stepfunctionOverviewThis AWS Solutions Construct implements an Amazon S3 bucket connected to an AWS Step Function.Note - This constructs sends S3 Event Notification to EventBridge, then triggers AWS Step Functions State Machine executions from EventBridge.An alternative architecture can be built that triggers a Lambda function from S3 Event notifications using aws-s3-lambda and aws-lambda-stepfunctions. Channelling the S3 events through Lambda is less flexible than EventBridge, but is more cost effective and has lower latency.Here is a minimal deployable pattern definition:Typescript//aws-s3-step-functionhasbeendeprecatedforCDKV2infavorofaws-s3-stepfunctions.//ThissampleusestheCDKV1syntaximport*ascdkfrom'@aws-cdk/core';import{S3ToStepFunction,S3ToStepFunctionProps}from'@aws-solutions-constructs/aws-s3-step-function';import*asstepfunctionsfrom'@aws-cdk/aws-stepfunctions';conststartState=newstepfunctions.Pass(this,'StartState');newS3ToStepFunction(this,'test-s3-step-function-stack',{stateMachineProps:{definition:startState}});Python# aws-s3-step-function has been deprecated for CDK V2 in favor of aws-s3-stepfunctions.# This sample uses the CDK V1 syntaxfromaws_solutions_constructs.aws_s3_step_functionimportS3ToStepFunctionfromaws_cdkimport(aws_stepfunctionsasstepfunctions,core)start_state=stepfunctions.Pass(self,'start_state')S3ToStepFunction(self,'test_s3_step_function_stack',state_machine_props=stepfunctions.StateMachineProps(definition=start_state))Java// aws-s3-step-function has been deprecated for CDK V2 in favor of aws-s3-stepfunctions.// This sample uses the CDK V1 syntaximportsoftware.constructs.Construct;importsoftware.amazon.awscdk.core.*;importsoftware.amazon.awscdk.services.stepfunctions.*;importsoftware.amazon.awsconstructs.services.s3stepfunction.*;finalPassstartState=newPass(this,"StartState");newS3ToStepFunction(this,"test_s3_stepfunctions_stack",newS3ToStepFunctionProps.Builder().stateMachineProps(newStateMachineProps.Builder().definition(startState).build()).build());Pattern Construct PropsNameTypeDescriptionexistingBucketObj?s3.IBucketExisting instance of S3 Bucket object.
