The Data Mesh

James Serra explains what a data mesh is:

Its goal is to treat data as a product, with each source having its own data product manager/owner (who are part of a cross-functional team of data engineers) and being its own clearly-focused domain that has an autonomous offering, becoming the fundamental building blocks of a mesh, leading to a domain-driven distributed architecture. Note that for performance reasons, you could have a domain that aggregates data from multiple sources. Each domain should be discoverable, addressable, self-describing, secure (governed by global access control), trustworthy, and interoperable (governed by an open standard). Each domain will store its data in a data lake and in many cases will also have a copy of some of the data in a relational database (see Data Lakehouse defined for why you still want a relational database in most cases).

I’ll have to think more about this before I’m convinced. I’ll also need to think about the Aristotelian opposite of the data mesh.
