Key summary

This article discusses Apache Airflow, a workflow orchestration platform that enables the definition, scheduling, and monitoring of complex data pipelines as code. It covers various aspects of Airflow, including DAGs, operators, sensors, hooks, and task flow API, as well as best practices for operations and deployment.

TL;DR

  • Apache Airflow is a workflow orchestration platform that defines, schedules, and monitors data pipelines as code.
  • DAGs are the fundamental unit in Airflow, consisting of operators, sensors, and hooks.
  • TaskFlow API is the modern way to write DAGs using decorators instead of operator instantiation.
  • Deferrable operators allow for non-blocking execution and fan-out/fan-in functionality.
  • Best practices include using none_failed for fault-tolerant pipelines and 2-3 retries with exponential backoff for most tasks.
  • Airflow supports object-oriented scheduling, data-driven workflows, and time-based and event-driven scheduling.
  • Catchup is automatic backfill of missed DAG runs, and connections store authentication credentials centrally.
