Airflow delete dag

  • May 01, 2017 · DAG(Directed Acyclic Graph) 1) The main concept of airflow is a DAG (Directed Acyclic Graph). A DAG contains vertices and directed edges. 2) In a DAG, you can never reach to the same vertex, at which you have started, following the directed edges. Otherwise your workflow can get into an infinite loop.
  • 2 days ago · Occasionally, Airflow DAGs get stuck in the running state but don’t want to run any tasks. From my observations, it happens mostly when we clear many DAG runs in one DAG because we want to reprocess a large number of tasks. To avoid this problem, I suggest using the backfill command to restart only a small subset of DAGS.
  • Airflow 1.10.9: Fixed an issue that caused BigQuery operators from backported providers to fail when DAG serialization was turned on. The Airflow web server UI will now correctly reload when the plugin folder is modified. Rendered template_fields can now be displayed without accessing DAG files.

  • Dec 14, 2020 · DAG_NAME.py is the DAG to delete. Airflow 1.9.0: The metadata for deleted DAGs remains visible in the Airflow web interface. Airflow 1.10.0 or later: You can use the gcloud tool to remove the DAG metadata .
  • What’s up DAG? Now it’s time to learn the basics of implementing Airflow DAGs. Through hands-on activities, you’ll learn how to set up and deploy operators, tasks, and scheduling.
  • After the DAG completes, the data warehouse is in a new state and can be requeried to refresh downstream data products, for example as would be done with the starschema DAG. Staging flow ¶ Staging is the process where you pick up data from a source system and load it into a ‘staging’ area keeping as much as possible of the source data intact.
  • You have to add a task depends on you metadatadb (sqllite, PostgreSql, MySql..) that delete XCOM once the DAG run is finished. delete_xcom_task = PostgresOperator( task_id='delete-xcom-task', postgres_conn_id='airflow_db', sql="delete from xcom where dag_id=dag.dag_id and task_id='your_task_id' and execution_date={{ ds }}", dag=dag)

  • May 20, 2020 · We remove all data from Mysql and Postgres as well as remove file from S3. ignore_errors means that we don’t care if action fails (if there is no such file on S3 or table in the database). By the way, good approach here would be to move S3 file path into Catcher variable and reuse it in `S3:get` (Step #3) and inside delete step, to reduce ...
  • A DAG can have many branches and you can decide which of them to follow and which to skip at execution time. This creates a resilient design because each task can be retried multiple times if an error occurs. Airflow can even be stopped entirely and running workflows will resume by restarting the last unfinished task.
  • Run subsections of a DAG for a specified date range. If reset_dag_run option is used, backfill will first prompt users whether airflow should clear all the previous dag_run and task_instances within the backfill date range. If rerun_failed_tasks is used, backfill will auto re-run the previous failed task instances within the backfill date range.
  • Jul 17, 2019 · Airflow does not allow to set up dependencies between DAGs explicitly, but we can use Sensors to postpone the start of the second DAG until the first one successfully finishes. ExternalTaskSensor To configure the sensor, we need the identifier of another DAG (we will wait until that DAG finishes).

  • From the Airflow UI portal, it can trigger a DAG and show the status of the tasks currently running. Let’s start to create a DAG file. It’s pretty easy to create a new DAG. Firstly, we define some default arguments, then instantiate a DAG class with a DAG name monitor_errors, the DAG name will be shown in Airflow UI.

  • The dag_id is the identifier used internally by Airflow, you cannot have another DAG with the same name. A DAG is created using the arguments we pass to its constructor (DAG()), if this is the first time you pass arguments to a Python method let me highlight a few things: we pass three arguments with the format param_name=value
  • Conceptually an Airflow DAG is a proper directed acyclic graph, not a DAG factory or many DAGs at once. Note that you can still write dynamic DAG factories if you want to create DAGs that change based on input. - No optimization: the contract is simple, Airflow executes the tasks you define.

I'm running 5 DAG's which have generated a total of about 6GB of log data in the base_log_folder over a months period. I just added a remote_base_log_folder but it seems it does not exclude logging to the base_log_folder.. Is there anyway to automatically remove old log files, rotate them or force airflow to not log on disk (base_log_folder) only in remote storage?
