Hi everyone, I’m currently working on Issue #44003, which aims to expand the reference points for the new Deadline Alerts feature in Airflow 3.1.
In my initial discussions with the issue maintainer (Ferruzzi), we noted that there has been significant refactoring around Serialized DAGs recently. Ferruzzi raised a valid point regarding whether SerializedDagLastUpdatedDeadline is still a relevant or useful reference point in the current architecture. I’d love to hear from the community: is "DAG metadata freshness" still a practical trigger you'd use, or should we deprioritize this in favor of more high-demand areas? Following that thought, Ferruzzi also suggested that there is a growing need for Task-level deadlines. To ensure we address the gaps left by the legacy SLA system, I’m interested in hearing about your specific use cases for TaskInstance monitoring. Are there specific lifecycle events—such as time spent in a queued state or delays in a task's start_date—that you would like to see as standardized reference points? Your feedback will help shape a potential follow-up proposal for a more exhaustive list of Task-level deadlines. Thanks & Regards, Ashish Rana
