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.
