Understanding core features of Apache Airflow

Apache Airflow is an open source platform that provides a comprehensive solution for orchestrating complex data pipelines. Born out of the need to manage Airbnb’s data workflows, Airflow has gained widespread adoption due to its flexibility, scalability, and active community support and is now one of the most widely used orchestration platforms.

Airflow uses concepts such as DAGs and operators, which are the fundamental building blocks that you need to work with when developing an orchestration solution using Airflow:

  • Directed Acyclic Graphs (DAGs): At the heart of Airflow’s orchestration philosophy are DAGs. A DAG is a collection of tasks with defined dependencies, where the direction of dependencies forms a directed graph, and there are no cycles. Each node in the graph represents a task, while edges denote the order in which tasks should be executed.
  • Operators: Tasks within an Airflow DAG are implemented...
