Azure SQL Data Warehouse seamless integration with Azure Data Lake Store
PolyBase in Azure SQL Data Warehouse now supports Azure Data Lake Store.

The current connectivity to Data Lake Store and Blob storage do not have computation pushdown capabilities and are primarily intended to be a loading mechanism.
