driftStatus

Status of the stack instance's actual configuration compared to the expected template and parameter configuration of the stack set to which it belongs.

• DRIFTED: The stack differs from the expected template and parameter configuration of the stack set to which it belongs. A stack instance is considered to have drifted if one or more of the resources in the associated stack have drifted.

• NOT_CHECKED: CloudFormation hasn't checked if the stack instance differs from its expected stack set configuration.

• IN_SYNC: The stack instance's actual configuration matches its expected stack set configuration.

• UNKNOWN: This value is reserved for future use.
