Ultrabug created AIRFLOW-1135:
---------------------------------
Summary: Clearing XCom data from previous executions
Key: AIRFLOW-1135
URL: https://issues.apache.org/jira/browse/AIRFLOW-1135
Project: Apache Airflow
Issue Type: New Feature
Components: db
Reporter: Ultrabug
It looks like XCom data from previous executions of tasks are never cleared
from database and that there's no easy way to do so.
Since XComs are created by execution_date of a task, when a task heavily uses
XComs (like 20 000+) we can end up with a large xcom table on the database.
Is there something I'm missing about cleaning up those previous XComs from
database (since they're not used anymore) ?
Would you accept the idea of having a new PR providing a helper to remove them ?
Thanks
