Xcom has limits. In Airflow 2 you can define a custom xcom backend see [documentation](https://airflow.apache.org/docs/apache-airflow/stable/concepts.html?highlight=xcom#custom-xcom-backend), [polidea article](https://www.polidea.com/blog/airflow-2-0-dag-authoring-redesigned/) I don't really know your use case but I'm not really sure if xcom are even needed here. Why not simply writing the delta (increment) to a folder in GCS in a known path? For example using `{{ ds }}` for daily runs or `{{ ts_nodash }}` for hourly runs then the loading job can just read the data from this known path without looking in xcoms. In any case since this is not a bug/feature request but more of a troubleshooting question for a specific ETL I'm closing this issue.
