dag = DAG( 'xcom_example', default_args=default_args, schedule_interval=timedelta(days=1), )

Only push IDs or S3 paths rather than raw data. airflow xcom exclusive

The metadata DB stores only small JSON pointers; actual data lives in S3 with an automatic 24-hour TTL. Debugging becomes linear: each task’s inputs are fully determined by its explicit upstream keys. dag = DAG( 'xcom_example'

You can explicitly push data using the xcom_push method inside the function. This is useful if you need to push multiple values. airflow xcom exclusive
