In this post you will learn some of the best patterns/tricks author has learned during my time creating Step Functions workflows. By Lukas Fruntke.
Since it has been introduced in June Step Functions Workflow Studio proved its value to me several times. As its a low-code editor with the most common configurations already baked-in, the effort of writing/designing a workflow with Amazon States Language plummeted. Those minutes and hours handwriting workflows with 100 lines++ are finally over for good, which is something you must not ignore when dealing with Step Functions.
The main points captured in this article:
- Make use of the Step Functions Workflow Studio
- Utilize the service integrations
- Use .waitForTaskToken

Excellent!
