Airflow clear Tasks 是否也会从数据库中删除数据？

Question

We have a use case where we have to populate fresh data in our DB. There is already old data present from the successful DAG run in our DB . Now we need to delete the old data and re run the task. Airflow already provides a command to clear selection.

airflow clear -dx occupancy_reports.* -t building -s 2022-04-01 -e 2022-04-30

Will running this also delete the data from the Database and then populate fresh data ?

Answer 1

I guess you meant : airflow **tasks** clear ...

It is only clear the set of task instance, as if they never ran (it is not rollback)
