DAG list page: show task state counts for the most recent DAG run per DAG #66947

Description

Airflow 2 showed a "Recent Tasks" column on the DAG list page with colored circles representing the task state breakdown of the most recent DAG run for each DAG (running, queued, failed, up_for_retry, success, etc.).

Airflow 3 removed this entirely. There is no equivalent anywhere in the UI.

The request is to bring back per-DAG task state counts for the most recent run on the DAG list page, with the ability to click a state count to jump directly to the filtered task list or DAG run for that DAG.

Use case/motivation

The "Recent Tasks" column served two purposes: health overview and quick navigation.

For health overview, you could scan the entire DAG fleet in one glance and immediately spot:

  • DAGs stuck in running or queued state (hung tasks)
  • DAGs with tasks in up_for_retry (transient failures in progress)
  • DAGs with failed tasks before the whole run completed

For quick navigation, clicking a state circle took you directly to the relevant tasks or DAG run filtered by that state, without having to go through multiple pages.

In Airflow 3 none of this is possible from the DAG list. To check task-level state for any DAG you have to click into it, navigate to the Tasks tab or Grid view, and check manually, one DAG at a time. In a fleet of dozens of DAGs this makes routine health checks and incident triage significantly slower.
