ramitkataria opened a new pull request, #75226:
URL: https://github.com/apache/airflow/pull/75226
Most Amazon provider operators that accept both ``deferrable`` and
``wait_for_completion`` defer whenever ``deferrable`` is True, so an explicit
``wait_for_completion=False`` is ignored. Because ``deferrable`` defaults to
the ``[operators] default_deferrable`` option, a deployment-wide setting
overrides a task-level choice not to wait. A start operator paired with its
companion sensor then waits twice, and the operator's shorter waiter can fail
the task before the sensor's budget runs out. The Comprehend system test hit
this.
The next major release will defer only when ``wait_for_completion`` is True,
matching the SageMaker Processing/Training/Transform, DMS, Redshift
Resume/Pause and EMR job flow operators. Warning about the affected combination
now lets Dag authors pin either behavior before it changes. Comprehend goes
first so the shared decision point and warning wording can be settled on one
service before the rest of the provider follows.
