Azure Data Factory (ADF) seamlessly integrates with PolyBase, the most efficient way to load data into SQL Data Warehouse (DW), to empower you to ingest data from 80+ data stores into SQL DW performantly. If your source data is PolyBase compatible, copy activity can directly invoking PolyBase on your behalf to save your from constructing the complex T-SQLs; if your source data is not originally supported by PolyBase, copy activity additionally provides built-in staged copy to automatically convert data into compatible format before using PolyBase to load the data.
Now ADF further enriches the PolyBase integration to support:
- Loading data from Azure Data Lake Storage Gen2 with account key or managed identity authentication;
- Loading data from Azure Blob configured with VNet service endpoint, either as the original source or as staging store, in which case underneath ADF automatically switch to abfss:// scheme to create external data source as required by PolyBase.
