It can be useful when you need to add an operator to a DAG for organizational purposes<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to import the airflow DummyOperator<\/h2>\n\n\n\n<p>The DummyOperator is defined in the airflow.operators.dummy_operator module and can be imported by typing the below command<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>from airflow.operators.dummy_operator import DummyOperator<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Airflow DummyOperator arguments<\/h2>\n\n\n\n<p>DummyOperator in airflow is very simple to use. Below are the few arguments supported by DummyOperator:<\/p>\n\n\n\n<ul>\n<li><strong>task_id<\/strong>(Mandatory): a unique identifier for the task.<\/li>\n\n\n\n<li><strong>dag<\/strong>(Mandatory): the DAG object to which the task belongs.<\/li>\n\n\n\n<li><strong>owner<\/strong>(optional): the owner of the task.<\/li>\n\n\n\n<li><strong>email_on_retry <\/strong>(optional): if True, an email will be sent to the task&#8217;s owner whenever the task is retried after a failure.<\/li>\n\n\n\n<li><strong>start_date<\/strong> (optional): the date and time at which the task should start running.<\/li>\n\n\n\n<li><strong>retries <\/strong>(optional): the number of times the task should be retried in case of failure.<\/li>\n\n\n\n<li><strong>retry_delay <\/strong>(optional): the amount of time to wait between retries.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Airflow DummyOperator example<\/h2>\n\n\n\n<p>Below is a simple example of airflow DummyOperator<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">from airflow import DAG\nfrom airflow.operators.dummy_operator import DummyOperator\nfrom datetime import datetime\n\nmy_dag = DAG(\n    dag_id='dummyoperator_dag',\n    start_date=datetime(2022, 2, 21),\n    schedule_interval='@daily'\n)\n\ndummy_task = DummyOperator(\n    task_id='dummy_task',\n    dag=my_dag\n)\n<\/pre>\n\n\n\n<p>The DAG is named &#8220;dummyoperator_dag&#8221; and has a start date of February 21, 2022.
