Yes, I have experience working with Apache Airflow. It is a platform for programmatic workflow orchestration that allows creating, scheduling, and monitoring complex task chains.
Airflow uses Directed Acyclic Graphs (DAGs) to describe dependencies between tasks. Each task is a separate operator, such as executing a Python function, running an SQL query, or calling an external service.
Example of a simple DAG in Python:
from airflow import DAG
from airflow.operators.bash import BashOperator
from datetime import datetime
default_args = {'start_date': datetime(2024, 1, 1)}
dag = DAG('example_dag', default_args=default_args, schedule_interval='@daily')
t1 = BashOperator(task_id='print_date', bash_command='date', dag=dag)
t2 = BashOperator(task_id='sleep', bash_command='sleep 5', dag=dag)
t1 >> t2 # t2 will run after t1
Airflow is widely used for automating ETL processes, data processing, and other tasks requiring reliable management of execution sequences.
