Master Data Management (Python, PostgreSQL, RabbitMQ, Airflow, FastAPI) overview

A centralized master data management hub that maintains golden records for customers, products, suppliers, and organizational hierarchies across the enterprise. FastAPI exposes CRUD and match-merge APIs with configurable survivorship rules for conflict resolution. PostgreSQL stores the master records with full change history and lineage tracking. RabbitMQ distributes change events to downstream consumers ensuring eventual consistency across systems. Apache Airflow orchestrates batch data quality jobs, deduplication pipelines, and cross-reference reconciliation. The tradeoff is the political complexity of data ownership governance and the computational cost of probabilistic matching at scale.
