Note¶

The historical data of measurement needs to be deleted by the user, otherwise the old data may be queried or the query may fail after re-creating the measurement point.
Make sure that there is no data of this measurement to be uploaded, otherwise the deletion will fail.
After calling this API, whether the storage policy of the measurement point is canceled will be checked, so the user needs to confirm that the storage policy of the measurement point has been canceled.
Data will be deleted through Open API by calling asynchronous tasks, so timeliness will not be guaranteed.
