tempdb improvements |
By default, a new installation of SQL Server on Linux creates multiple tempdb data files based on the number of logical cores (with up to eight data files). This setting doesn't apply to in-place minor or major version upgrades. Each tempdb file is 8 MB with an auto growth of 64 MB. This behavior is similar to the default SQL Server installation on Windows. |

| Non-root containers | SQL Server 2019 (15.x) introduces the ability to create safer containers by starting the SQL Server process as a non-root user by default. For more information, see Build and run SQL Server containers as a non-root user. |
