URL: https://github.com/apache/airflow/pull/18814
This PR adds the possibility to specify a `wait_for_completion` flag in an
`AwsGlueJobOperator` to indicate whether or not to wait for job run completion.
This is really useful because you can use the `run_id` available via `xcom`
and put an `AwsGlueJobSensor` in the downstream to wait for completion.
With this pattern (fire & forget + sensor) we avoid re-launching a Glue job
if the task fails while waiting for completion.
E.g: We create the `run_job` task and put a `sensor_job` in the downstream.
```python
# ...
from airflow.providers.amazon.aws.sensor.glue import AwsGlueJobSensor
from airflow.providers.amazon.aws.operators.glue import AwsGlueJobOperator
# ...
script_args = {
"--timestamp": "{{ ts }}",
}
run_job = AwsGlueJobOperator(
task_id="run_glue_job",
job_name="exmaple-glue-job",
script_args=script_args,
wait_for_completion=False,
)
sensor_job = AwsGlueJobSensor(
task_id="sensor_glue_job",
job_name="exmaple-glue-job",
run_id="{{ ti.xcom_pull(task_ids='run_glue_job') }}"
)
run_job >> sensor_job
# ...
```
