In AWS step functions, can I have multiple workflows share one same state object, and having the workflows work independently?

Essentially what I want it to have multiple workflows, and they would all be triggered exactly the same way by an upstream message, so I want to have one state object to serve as a start, then each workflow would work differently with various next steps depends on this start state's output. I do not want to use parallel because I want all these workflows to work independently.

Please advise. Thank you.

Solution

Start state of a State Machine (SM) cannot be shared with any other SM.

You can create a Lambda function that is triggered by an upstream message which then triggers all other SMs asynchronously.
