Résumé
The Data Mesh architecture is gaining popularity as a new approach to data management within modern organizations. A key component of this architecture is the metadata catalog, which provides a centralized repository for documenting and discovering data products across different teams. However, maintaining an accurate and secure catalog in the context of this architecture is challenging. In this paper, we explore the benefits of using blockchain technology to power the metadata catalog in a Data Mesh architecture. Indeed, blockchain provides a decentralized and immutable ledger that can help to ensure the accuracy and consistency of metadata across different teams. It provides a secure and transparent way of tracking changes and access to the metadata. We discuss the potential advantages of using blockchain for metadata catalog, including data security, data provenance, and data ownership. We also examine the potential challenges and limitations of using blockchain technology in the context of Data Mesh architecture. Overall, we argue that blockchain-powered metadata catalogs have the potential to enhance the efficiency and reliability of data management in a Data Mesh.
