Polybase
PolyBase enables your SQL Server instance to process Transact-SQL queries that read data from external data sources. SQL Server 2016 and higher can access external data in Hadoop and Azure Blob Storage. Starting in SQL Server 2019, you can now use PolyBase to access external data in SQL Server, Oracle, Teradata, and MongoDB.
