operationId

The unique identifier for this StackSet operation.

If you don't specify an operation ID, the SDK generates one automatically.

The operation ID also functions as an idempotency token, to ensure that CloudFormation performs the StackSet operation only once, even if you retry the request multiple times. You can retry StackSet operation requests to ensure that CloudFormation successfully received them.

Repeating this StackSet operation with a new operation ID retries all stack instances whose status is OUTDATED.
