Add Support for Dynamic Execution Names in EventBridge Pipes for Step Functions

[kashyapm94]

Describe the feature

Currently, the PipeTargetStateMachineParameters struct used in EventBridge Pipes only supports the InvocationType field. There is no way to optionally specify a dynamic name for the Step Function execution.

Use Case

I'm building a pipeline like this:

SQS -> EventBridge Pipe -> Step Function

I'd like to assign each Step Function execution a name derived from the message payload. For example, with a message containing:

{
  "user_id": "12345",
  "timestamp": "20250612"
}

I would want to generate an execution name like: execution-12345-20250612

Proposed Solution

Update the PipeTargetStateMachineParameters struct in the types.go file to include support for the optional Name field, which allows setting a dynamic Step Function execution name (with a maximum length of 80 characters, as enforced by the AWS API).

Don't know how you build your pipe in detail, but the execution name could be optionally set via your step function client when calling StartExecution https://github.com/aws/aws-sdk-go-v2/blob/5c12a3b4209ebed699b200c3eb7a795669753f43/service/sfn/api_op_StartExecution.go#L145

@wty-Bryant I use Terraform for CDK and while using pipes, it's possible to define target parameters. But while using a SFN as a target, the only parameter available for SFN is invocationType.

Could you show Go v2 code that you use to create EventBridge pipe and invoke step func execution

@wty-Bryant I don’t have a snippet right now, plus I usually write the infra in Python but here’s the CDK implementation in Go

Where the TargetParameter can be defined

Well CDK Go is totally another repo owned by other team, which SDK Go v2 can not guarantee consistency with considering service operation request/response
