This topic provides an overview of how Python is integrated with SQL Server, including the security model, the components in the database engine that support external script execution, and new components that enable interoperability of Python with SQL Server. For details see the linked topics.
Important
Support for Python is available beginning with SQL Server 2017. This is a pre-release feature and subject to change.
SQL Server Machine Learning Services (In-Database) installs the Anaconda distribution of Python, and the Python 3.5 runtime and interpreter. This ensure near-complete compatibility with standard Python solutions. Python runs in a separate process from SQL Server, to ensure that database operations are not compromised.
For more information about the interaction of SQL Server with Python, see Python Interoperability
The extensibility framework introduced in SQL Server 2016 now supports execution of Python script, through the addition of new language-specific components. These components improve data exchange speed and compression, while providing a secure, high-performance platform for running external scripts.
For detailed description of the components that support Python, such as the [!INCLUDErsql_launchpad_md] and PythonLauncher, see New Components.
Python tasks execute outside the SQL Server process, to provide security and greater manageability.
All tasks are secured by Windows job objects or SQL Server security. Data is kept within the compliance boundary by enforcing SQL Server security at the table, database, and instance level. The database administrator can control who has the ability to run Python jobs, monitor the use of Python scripts by users, and view the resources consumed.
For details, see Security for Python
In SQL Server Enterprise Edition, you can use Resource Governor to manage and monitor resource use of external script operations, including R script and Python scripts.
For more information, see Resource Governance for R.
