SQL Server 2019 or SQL Server 2019 big data cluster can use PolyBase external tables to connect to other data sources.
SQL Server 2019 or SQL Server 2019 big data cluster can use PolyBase external tables to connect to other data sources.
### External table over Generic ODBC data source
The [data-virtualization/generic-odbc](data-virtualization/generic-odbc) folder contains samples that demonstrate how to query data in MySQL & PostgreSQL using external tables and generic ODBC data source. The generic ODBC data soruce can be used only in SQL Server 2019 on Windows.
### External table over Hadoop
The [data-virtualization/hadoop](data-virtualization/hadoop) folder contains samples that demonstrate how to query data in HDFS using external tables. This demonstrates the functionality available from SQL Server 2016 using the HADOOP data source.
### External table over Oracle
The [data-virtualization/oracle](data-virtualization/oracle) folder contains samples that demonstrate how to query data in Oracle using external tables.
### External table over Storage Pool
SQL Server 2019 big data cluster contains a storage pool consisting of HDFS, Spark and SQL Server instances. The [data-virtualization/storage-pool](data-virtualization/storage-pool) folder contains samples that demonstrate how to query data in HDFS inside SQL Server 2019 big data cluster.
### External table over Oracle
SQL Server 2019 uses new ODBC connectors to enable connectivity to SQL Server, Oracle, Teradata, MongoDB and generic ODBC data sources.
The [data-virtualization/oracle](data-virtualization/oracle) folder contains samples that demonstrate how to query data in Oracle using external tables.
## __[deployment](deployment/)__
The [deployment](deployment) folder contains the scripts for deploying a Kubernetes cluster for SQL Server 2019 big data cluster.
