Airflow , bashOperator and other

  1. BashOperator: This operator allows you to execute a bash command or script as a task within your DAG.

  2. PythonOperator: This operator enables you to run arbitrary Python functions as tasks within your DAG.

Besides these two, Airflow provides a wide range of operators to suit various needs. Some of the other commonly used operators include:

  • BranchPythonOperator: This operator allows you to execute different tasks in your DAG based on the result of a Python function.

  • DummyOperator: This operator is a simple no-op operator that can be used as a placeholder or to mark points in your DAG.

  • PythonVirtualenvOperator: Similar to the PythonOperator, but it executes within a virtual environment.

  • SubDagOperator: This operator allows you to include a DAG as a task within another DAG, effectively creating a hierarchical structure.

  • EmailOperator: This operator sends an email as a task in your DAG.

  • HttpOperator: This operator enables you to make HTTP requests as tasks within your DAG.

  • PostgresOperator, MySqlOperator, SqliteOperator: These operators allow you to execute SQL commands or scripts against different databases.

  • Sensor operators: Airflow provides a variety of sensor operators (e.g., HttpSensor, SqlSensor, S3KeySensor) to wait for certain conditions to be met before proceeding with the DAG.
