When should I use Apache Airflow instead of Luigi?

Scheduling and orchestrating complex DAG-based data pipelines at scale with a mature ecosystem. Teams needing hundreds of pre-built provider integrations for databases, clouds, and SaaS tools. Monitoring, alerting, and auditing pipeline runs via a rich web UI with full task history

When should I use Luigi instead of Apache Airflow?

Simple dependency-based task scheduling without a heavy deployment footprint. Teams migrating off cron jobs who need basic task dependency management with file-based checkpointing. Workflows that naturally map to file system outputs as task completion markers

What are the main weaknesses of Apache Airflow?

DAGs defined in Python can become hard to maintain and test in large codebases. Dynamic DAGs and parameterized runs are complex to implement correctly without anti-patterns. Resource-heavy deployment requires a database, scheduler, and workers to run at minimum

What are the main weaknesses of Luigi?

No built-in retry logic, alerting, or backfill support out of the box. Web UI is minimal compared to Airflow, Prefect, or Dagster. Limited active development; the ecosystem has stagnated compared to modern orchestrators

How Python Data Engineers Use These Tools

Apache Airflow

Python data engineers define pipelines as Directed Acyclic Graphs (DAGs) using Airflow's Python SDK. DAGs are written as .py files that instantiate Operators — PythonOperator for custom logic, BashOperator for shell commands, and provider-specific operators for Postgres, S3, BigQuery, and Snowflake. Airflow is the industry-standard orchestrator for scheduling ETL jobs, managing dependencies between tasks, and handling retries in production data pipelines.

Luigi

Luigi is used at companies like Spotify to orchestrate multi-step batch jobs — engineers subclass `luigi.Task`, define `requires()` for dependencies and `output()` for targets, and Luigi's scheduler ensures each task runs only once its upstream tasks have produced their outputs, with automatic retry on failure.
