Choosing Standard or Express Workflows - AWS Step Functions

Choosing Standard or Express Workflows

AWS Step Functions offers Standard Workflows as the default workflow type, with the option to choose Express Workflows.

You can choose Standard Workflows when you need long-running, durable, and auditable workflows, or Express Workflows for high-volume, event processing workloads.Your state machine executions will behave differently, depending on which Type you select. The Type you choose cannot be changed after your state machine has been created.
