Parameters
project_idOptional, the Google Cloud project ID in which to work (templated). If set to None or missing, the default project_id from the Google Cloud connection is used.
topicRequiredthe topic to delete. Do not include the full topic path. In other words, instead of projects/{project}/topics/{topic}, provide only {topic}. (templated)
fail_if_not_existsIf True and the topic does not exist, fail the task
gcp_conn_idThe connection ID to use connecting to Google Cloud.
delegate_toThe account to impersonate using domain-wide delegation of authority, if any. For this to work, the service account making the request must have domain-wide delegation enabled.
retry(Optional) A retry object used to retry requests. If None is specified, requests will not be retried.
timeout(Optional) 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.

If set as a string, the account must grant the originating account the Service Account Token Creator IAM role.

By default, if the topic does not exist, this operator will not cause the DAG to fail.
with DAG('successful DAG') as dag:PubSubDeleteTopicOperator(project_id='my-project', topic='non_existing_topic')
The operator can be configured to fail if the topic does not exist.
with DAG('failing DAG') as dag:PubSubDeleteTopicOperator(project_id='my-project', topic='non_existing_topic', fail_if_not_exists=True,)
Both project_id and topic are templated so you can use Jinja templating in their values.
