Fabric Data Warehouse Writer overview
Microsoft Fabric is an all-in-one analytics platform created for businesses and data professionals. The platform handles everything from data science and real-time analytics to data storage and data migration.
All of the data utilized within Fabric is stored in OneLake. OneLake is a single, unified, logical data lake that’s responsible for supporting all of the Fabric workloads. OneLake is built on top of Azure Data Lake Storage (ADLS) Gen2 and can support any type of file, structured or unstructured. All Fabric data items like data warehouses and lakehouses store their data automatically in OneLake in Delta Parquet Table format. On the other hand, raw files (unstructured) can be stored under the "Files" folder in the OneLake storage (see Fabric Lakehouse File Writer).
Fabric Data Warehouse Writer is a target adapter that writes to the SQL endpoint of the Microsoft Fabric Data Warehouse tables. It uses ADLSGen2 as the temporary staging location before copying the data to the Fabric Data Warehouse tables. Fabric Data Warehouse Writer authenticates the staging location using the Storage Account’s name and its Access Key. You will need to provision and have ADLSGen2 access. Fabric Data Warehouse Writer supports authentication using Active Directory Password with a Fabric username and password. Authentication using OAuth is not currently supported.
