UI latency pausing DAGs from main /dags page (Airflow 3.1.4, Celery + Docker Compose)

[marcosmartinezfco]

Apache Airflow version

Other Airflow 3 version (please specify below)

If "Other Airflow 3 version" selected, which one?

3.1.4

What happened?

When navigating the main DAGs list page /dags UI, clicking the pause toggle for a DAG result in significant latency before the UI reflects the new state. Users see a long delay between the click and the toggle animation updating.

However, when pausing the same DAG from its detail view (inside the DAG view), the action is much faster and responsive.

What you think should happen instead?

Pausing a DAG from the main DAGs list should be as responsive as pausing from the DAG detail view. Latency should be minimal (<1 second ideally) on both pages.

How to reproduce

1. Deploy Airflow 3.1.4 using Docker Compose + Celery.
2. Navigate to the main UI DAGs list page.
   3.Click the pause toggle on any listed DAG.
3. Observe the long delay before the UI updates.
4. Navigate to the individual DAG view and pause the same DAG — observe the faster response.
