Apply branching logic with BranchSQLOperator, BranchPythonOperator, BranchDayOfWeekOperator, BranchDateTimeOperator, and ShortCircuitOperator
Manage DAG dependencies and use TaskGroups ,Utilize TriggerDagRunOperator , ExternalTaskSensor and use hooks such as PostgresHook and SHook
Manage resources with pools and task priorities
Learn about different types of executors: SequentialExecutor and LocalExecutor and learn the Transition from SequentialExecutor to LocalExecutor
Explore the Airflow metadata database and Manage roles and create users with different roles including admin, public, user, and operator roles
Set and manage task-level and DAG-level SLAs and handle SLA misses
Address issues like zombie tasks, SIGTERM, and SIGKILL errors
Requirements:
Knowledge of Python
Rest we will cover to learn Airflow from scratch
Familiarity with command-line interfaces.
Understanding of database concepts is a plus but not required
