Elliott Cordo emphasizes the perils of tightly-coupled systems in data engineering, particularly in analytics where complexity hinders evolution. He advocates for Data Contracts as a solution, drawing on the microservice architecture's principles where smaller, independent services interface through defined APIs. His approach showcases that a unified SQL environment often leads to tighter coupling, making systems fragile. Data Contracts create formal agreements between data producers and consumers, allowing for adaptations in technology while minimizing disruptions across systems, ultimately contributing to the agility required in modern data environments.
In analytic systems, tight coupling has been the norm, leading to complex structures that are difficult to adapt or change without significant risk.
Data contracts establish a formal agreement between data producers and consumers, allowing transitions between systems and databases while maintaining independence.
