WHAT IT DOES

What StartWorkflowInstances does on Alibabacloud Dataworks

WHY IT NEEDS A POLICY

Why StartWorkflowInstances needs a policy

StartWorkflowInstances triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

StartWorkflowInstances Rate-limited

StartWorkflowInstances stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
