When should I use Argo Workflows instead of Hamilton?

Kubernetes-native workflow orchestration for containerized workloads running on Kubernetes. ML training pipelines and batch jobs where each step runs in an isolated container. Teams already operating Kubernetes who want workflow automation without adding another system

When should I use Hamilton instead of Argo Workflows?

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

What are the main weaknesses of Argo Workflows?

Requires Kubernetes expertise to install, configure, and operate effectively. YAML-heavy workflow definitions become verbose and hard to maintain for complex graphs. Not Python-native; the Python SDK is secondary to the YAML-first workflow API

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

How Python Data Engineers Use These Tools

Argo Workflows

Python data engineers use Argo Workflows on Kubernetes to orchestrate containerised data pipelines where each task runs as an isolated Docker container. Python scripts are packaged as container images and executed as workflow steps, enabling reproducible, scalable batch processing. Argo is particularly popular in ML engineering teams for model training pipelines and in cloud-native data platforms where Kubernetes is the deployment target.

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.
