In reality, it represents a new operating model for managing the entire lifecycle of data and AI — from Delta tables to MLflow and streaming pipelines. This article breaks down the essential components and explains why leaders must rethink how data platforms operate. The lakehouse collapses…

Using Kaggle data on a Microsoft Fabric trial exposed more than ingestion mechanics. It revealed how quickly unclear loading patterns turn into trust and accountability problems. This article explains what broke and why it matters to leaders. How data enters OneLake determines how defensible the analytics built on it will be. I got access to…
