Description

Description

It's possible to add a note to a dag run and task instances. But it's not apparent from the UI (in Airflow 3) that there is a note.

  • In the grid view, there would be a small icon on top of the dag/task bloc in Airflow 2
  • Moreover, in the dag runs tab, it would be very helpful to be able to see the (partial) content of the note

Use case/motivation

I often go over failed dag runs to rety them. However, some dag runs fail for a good reason, making it useless to retry them. I tend to annotate those dag runs with a note. It's quite usefull to see what runs were annotated (and why), so that I can see from the list of dag runs or from the grid view which ones I already examined.

Research direction
Examine the grid view and dag runs tab components in the Airflow UI. Look for existing note icons (e.g., in Airflow 2) and API endpoints that return note data. The main files to modify are likely in airflow/www/ or similar UI directories. Check how dag run notes are stored and retrieved via the backend API to expose a note indicator.
