YoannAbriel opened a new pull request, #63522:
URL: https://github.com/apache/airflow/pull/63522
In Airflow 3, tasks transition from QUEUED to RUNNING via the execution API
(`ti_run` endpoint), not the legacy `TaskInstance._run_raw_task` path. The
`task.queued_duration` metric (`dag.{dag_id}.{task_id}.queued_duration` in
legacy format) is only emitted in the old path via
`emit_state_change_metric()`, so it's never recorded for tasks started through
the task SDK.
This adds the metric emission to `ti_run()` — selects `queued_dttm`,
`end_date`, and `queue` from the TI row and calls `DualStatsManager.timing()`
after the state update. Same first-attempt guard as the original (skips when
`end_date` is set).
Closes: #63503
