What is idempotent-pipeline-demo?

This demo GitHub repo is a Python FastAPI app that builds an idempotent data pipeline for enterprise integration, tackling duplicates, replays, and out-of-order messages from systems like OMS, WMS, or finance. You POST messages to ingest endpoints—single or batch up to 500—and it applies a five-branch decision to accept, skip, supersede, or quarantine them, staging clean data before materializing to production. Run it locally with SQLite via uvicorn, query states via GET endpoints, trigger jobs for compaction or reconciliation reports, and hit interactive docs at /docs.

Why is it gaining traction?

Unlike basic at-least-once brokers, this demo project design proves exactly-once processing with audit logs and quarantine for anomalies like same-version payload changes, plus correlation across sources without exactly-once guarantees. Developers dig the 10 test scenarios in pytest, quick Postgres migration, and reconciliation API that verifies no duplicates slipped through—perfect for a GitHub demo application with verifiable correctness. The staging/production layers and completeness checks make data lineage transparent.

Who should use this?

Backend engineers integrating microservices with Kafka or RabbitMQ, data pipeline devs handling retries in e-commerce or supply chain flows, or teams needing audit-ready ingestion for compliance. Ideal for prototyping idempotent flows in demo projects logic pro x style, or as a reference for github demo video walkthroughs.

Verdict

Solid demo project report for learning resilient pipelines—run the scenarios, see it dedup in action—but with 11 stars and 1.0% credibility score, it's early-stage; treat as educational reference, not production-ready core. Fork and extend for your github page demo.
