Applies to: SQL Server 2016 (13.x) and later - Windows only

Important

Stretch Database is deprecated in SQL Server 2022 (16.x) and Azure SQL Database. This feature will be removed in a future version of the Database Engine. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.

Stretch Database provides a set of extended events for troubleshooting.

For more info, see Extended Events. For info about how to start an extended events session for troubleshooting, see Create an Extended Events Session
