Apache Hamilton

Judgement

What it is

Framework or platform

What it does

A Python library where each function becomes a node in a data transformation graph, wired by parameter names, so pipelines are testable and can be visualised.

Adopt it when

Your feature engineering or ETL code has grown into tangled scripts and you want modular, documented steps without a heavy orchestrator.

Watch out

It is still incubating at Apache after leaving its original company, so governance and release cadence are in transition.
