title: How to delete XCOM objects once the DAG finishes its run in Airflow
body: <p>I have a huge json file in the XCOM which later I do not need once the dag execution is finished, but I still see the Xcom Object in the UI with all the data, Is there any way to delete the XCOM programmatically once the DAG run is finished. </p>
  
  <p>Thank you</p>
