ferruzzi opened a new pull request, #56159:
URL: https://github.com/apache/airflow/pull/56159
Adds async support to the existing SQS Notifier so it can be used as an
AsyncCallback for DeadlineAlerts, among other things
dags used for manual testing:
```python
from datetime import datetime, timedelta
from airflow.providers.amazon.aws.hooks.sqs import SqsHook
from airflow.providers.amazon.aws.notifications.sqs import SqsNotifier
from airflow.sdk import task, DAG
from airflow.sdk.definitions.deadline import DeadlineAlert,
DeadlineReference, AsyncCallback
PAST_DATE = datetime(1980, 8, 10, 2)
MSG_PREFIX = "SQS Testing Rnd 0:"
DEFAULTS = {"queue_url":
"https://sqs.us-east-1.amazonaws.com/324969868898/async-notifier-testing"}
def _sqs_callback(context):
SqsHook().send_message(**DEFAULTS, message_body=f"{MSG_PREFIX} Hook as
Callback -- {context['dag_run'].dag_id}")
@task
def send_sqs_message(message):
SqsHook().send_message(**DEFAULTS, message_body=message)
@task.bash(task_id='sleep_task')
def sleep_n_secs(seconds):
return f'sleep {seconds}'
with DAG(
"sqs_hook_via_taskflow",
tags=["sqs"]
):
send_sqs_message(message=f"{MSG_PREFIX} Taskflow -- {{{{ dag_run.dag_id
}}}} ")
with DAG(
"sqs_callback_on_success",
on_success_callback=_sqs_callback,
tags=["sqs"],
):
sleep_n_secs(1)
with DAG(
"sqs_notifier_as_callback",
on_success_callback=SqsNotifier(**DEFAULTS, message_body=f"{MSG_PREFIX}
Sync Notifier as callback -- {{{{ dag_run.dag_id }}}} "),
tags=["sqs"],
):
sleep_n_secs(1)
with DAG(
"sqs_notifier_as_deadline",
deadline=DeadlineAlert(
reference=DeadlineReference.FIXED_DATETIME(PAST_DATE),
interval=timedelta(0),
callback=AsyncCallback(
SqsNotifier,
kwargs={**DEFAULTS, "message_body": f"{MSG_PREFIX} Async
Notifier as Deadline -- {{{{ dag_run.dag_id }}}} "}
),
),
tags=["sqs"],
):
sleep_n_secs(1)
```
