             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
