Returns ``NOT_FOUND`` if the topic does not exist. After a topic is deleted, a new topic may be created with the same name; this is an entirely new topic with none of the old configuration or subscriptions. Existing subscriptions to this topic are not deleted, but their ``topic`` field is set to ``_deleted-topic_``. Example: >>> from google.cloud import pubsub_v1 >>> >>> client = pubsub_v1.PublisherClient() >>> >>> topic = client.topic_path('[PROJECT]', '[TOPIC]') >>> >>> client.delete_topic(topic) Args: topic (str): Name of the topic to delete. Format is ``projects/{project}/topics/{topic}``. retry (Optional[google.api_core.retry.Retry]): A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]): The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata that is provided to the method. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid.
