Below is the code for one of Shard DAG that generated by Airflow itself automatically after SmartSensor enabled. Which match my previous comment that retries is limited to 100 times and smart_sensor_timeout is overwritten to 24 hour, instead of the default 1 week in __init__. ``` # # Licensed to the Apache Software Foundation (ASF) under one # or more contributor license agreements.
