Q1. What is Microsoft Fabric and how is it different from Azure Synapse Analytics?
Microsoft Fabric is an all-in-one SaaS analytics platform that unifies data engineering, data integration, data science, real-time analytics, and business intelligence under a single license and a single storage layer called OneLake. Azure Synapse requires you to manage compute clusters, link storage accounts, and configure separate services for Spark and SQL. Fabric abstracts all of this -- your Lakehouse, Warehouse, Data Factory pipelines, Power BI reports, and ML notebooks all share one OneLake store automatically, eliminating data duplication and simplifying governance.
Q2. What is Direct Lake mode in Microsoft Fabric Power BI?
Direct Lake is a revolutionary query mode in Power BI that reads Delta Parquet files directly from OneLake without requiring a data import or a live DirectQuery connection to a database engine. This gives you Import-level query speed while always reflecting the latest data in the lake without scheduled refreshes. The engine transcodes the Delta files into VertiPaq in-memory format on the fly. For our analytics team, this eliminated the 2-hour nightly refresh cycle entirely.
