Data Products: A Case Against Medallion Architecture

If this is going to be a case against the Medallion architecture, we need to lawyer up on both ends and make a case for Medallion first—its significance, reasons behind its emergence, impact, and why it worked or didn’t work. And don’t worry, we’ll keep the defence short so we have the stage for what’s coming.What is the Medallion Architecture?The name itself compactly holds a visual of the entire architecture. The Medallion Architecture was coined as a way to describe a structured approach to organising data lakes into layers of quality. The name is cleverly metaphorical, drawing from the idea of medals (like in sports) to represent increasing levels of data refinement and quality: Bronze, Silver, and Gold.
