According to Wikipedia,
"Data mesh is a sociotechnical approach to build a decentralized data architecture by leveraging a domain-oriented, self-serve design (in a software development perspective), and borrows Eric Evans’ theory of domain-driven design and Manuel Pais’ and Matthew Skelton’s theory of team topologies."
I have no idea what any of that means.
If I were to guess, then Pyramid as a self service, no code/ low code analytic data modelling, query, visualisation and machine learning environment, agnostic in its data storage options, could, in the hands of those who are familiar with the Data Mesh concepts, be effectively used in that context.
Just a guess though.
Hope that helps.
