Summary
The current trend in data management is to centralize the responsibilities of storing and curating the organization’s information to a data engineering team. This organizational pattern is reinforced by the architectural pattern of data lakes as a solution for managing storage and access. In this episode Zhamak Dehghani shares an alternative approach in the form of a data mesh. Rather than connecting all of your data flows to one destination, empower your individual business units to create data products that can be consumed by other teams. This was an interesting exploration of a different way to think about the relationship between how your data is produced, how it is used, and how to build a technical platform that supports the organizational needs of your business.

IntroductionHow did you get involved in the area of data management?Can you start by providing your definition of a "data lake" and discussing some of the problems and challenges that they pose?What are some of the organizational and industry trends that tend to lead to this solution?You have written a detailed post outlining the concept of a "data mesh" as an alternative to data lakes. Can you give a summary of what you mean by that phrase?In a domain oriented data model, what are some useful methods for determining appropriate boundaries for the various data products?What are some of the challenges that arise in this data mesh approach and how do they compare to those of a data lake?One of the primary complications of any data platform, whether distributed or monolithic, is that of discoverability. How do you approach that in a data mesh scenario?A corollary to the issue of discovery is that of access and governance. What are some strategies to making that scalable and maintainable across different data products within an organization?Who is responsible for implementing and enforcing compliance regimes?One of the intended benefits of data lakes is the idea that data integration becomes easier by having everything in one place. What has been your experience in that regard?How do you approach the challenge of data integration in a domain oriented approach, particularly as it applies to aspects such as data freshness, semantic consistency, and schema evolution?Has latency of data retrieval proven to be an issue in your work?When it comes to the actual implementation of a data mesh, can you describe the technical and organizational approach that you recommend?How do team structures and dynamics shift in this scenario?What are the necessary skills for each team?Who is responsible for the overall lifecycle of the data in each domain, including modeling considerations and application design for how the source data is generated and captured?Is there a general scale of organization or problem domain where this approach would generate too much overhead and maintenance burden?For an organization that has an existing monolothic architecture, how do you suggest they approach decomposing their data into separately managed domains?Are there any other architectural considerations that data professionals should be considering that aren’t yet widespread?Contact Info
