When should I use Hamilton instead of Luigi?

Defining dataflow as pure Python functions where dependencies are resolved automatically by name. Feature engineering pipelines where lineage, documentation, and reusability across contexts matter. Teams who want to reuse the same function graph for training, serving, and batch processing

When should I use Luigi instead of Hamilton?

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 Hamilton?

Small community with fewer tutorials, integrations, and Stack Overflow answers than mainstream tools. No built-in scheduler — requires Airflow, Prefect, or a similar tool for recurring execution. Mental model shift required: functions define graph nodes implicitly, not through explicit wiring

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

Hamilton

Python data engineers use Hamilton to define feature engineering pipelines where each column or feature is a Python function whose parameters declare its dependencies. Hamilton builds the DAG from function signatures automatically — engineers add a new feature by writing a new function, and Hamilton wires it into the execution graph without any manual DAG configuration.

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.
