Résumé
This paper explores the implementation of a blockchain powered metadata catalog in a data mesh architecture. The metadata catalog serves as a critical component in managing data at scale, allowing for efficient discovery, access, and governance. By integrating blockchain technology, the metadata catalog can provide federated control, immutability, and transparency in managing metadata across a distributed network of data domains. This paper discusses the benefits of using blockchain technology in the metadata catalog and provides a proof-of-concept implementation of a blockchain-powered metadata catalog in a data mesh architecture using HyperLedger Fabric. The paper also highlights some challenges and potential solutions for adopting this approach, including scalability, interoperability, and governance concerns. Overall, this paper presents a novel approach for implementing a secure and federated metadata catalog in data mesh architecture that can improve the efficiency, reliability, and transparency of data management.
