create_glacier_job = GlacierCreateJobOperator(task_id="create_glacier_job", vault_name=VAULT_NAME)
JOB_ID = '{{ task_instance.xcom_pull("create_glacier_job")["jobId"] }}'

To wait on the status of an Amazon Glacier Job to reach a terminal state use GlacierJobOperationSensor

airflow/providers/amazon/aws/example_dags/example_glacier_to_gcs.py[source]

wait_for_operation_complete = GlacierJobOperationSensor(
    vault_name=VAULT_NAME,
    job_id=JOB_ID,
