Microsoft Fabric Data Warehouse

What is Microsoft Fabric Data Warehouse?
Microsoft Fabric’s Data Warehouse is a fully managed, high-performance analytical database that stores structured data in OneLake using Delta Parquet, an open data format. It supports SQL-based read and write operations, integrates seamlessly with other Fabric tools, and scales automatically to handle enterprise-level workloads.

Data Warehouse or Lakehouse

 

While both the Lakehouse and the Data Warehouse operate within OneLake and use Delta Parquet, their functionalities differ:

  • Lakehouse supports both structured and unstructured data but is read-only via SQL.
  • Data Warehouse is strictly for structured data and supports full SQL operations, including inserts, updates, and deletes.
