kwkwc opened a new pull request #19536:
URL: https://github.com/apache/airflow/pull/19536
I use ``task_instance_mutation_hook`` in Airflow ``2.2.1`` to dynamically
assign ``queue``:
```python
def task_instance_mutation_hook(task_instance: TaskInstance):
from airflow.settings import Session
session = Session()
dag_run = task_instance.get_dagrun(session)
conf = dag_run.conf
if conf and conf.get('queue'):
task_instance.queue = conf.get('queue')
```
Doing so allows you to specify the queue normally.
This is my database data:
But when I click on ``Instance Details`` or ``Clear`` in the UI, the
``queue`` is restored to its ``default`` value.
This is the database data that was restored after I clicked on ``one's
Instance Details``:
I found that the problem is that both ``Instance Details`` and ``Clear``
call the ``refresh_from_task`` and the current ``queue`` is overwritten.
