It answers the question that matters before a deploy: between two versions of a subject, what changed, and which of it breaks downstream consumers. What the name promises beyond that — AST rewriting, regenerated test payloads, automated PRs — belongs to the paid Enterprise edition, not this repository.
A Python server against a Confluent Schema Registry: it lists the registered subjects and diffs two versions of one, classifying each field change as breaking or backward-compatible. This is the free Community Edition.
- Every registered subject in the Schema Registry listed
- Two versions of a subject diffed — added, removed and modified fields
- Each change classified as breaking or backward-compatible
- A drift report naming the fields, their types and their defaults
Python, and `pip install -r requirements.txt`; the client runs `python server.py` as a stdio server. The registry URL, API key and API secret are passed as call arguments rather than environment variables, so the credentials travel with each request. Code rewriting, test-payload generation and PR creation are not in this edition.
One command plus a key — pip install -r requirements.txt, then supply credentials
