tempdb improvements |
By default, a new installation of [!INCLUDE ssnoversion-md] on Linux creates multiple tempdb data files based on the number of logical cores (with up to 8 data files). This does not 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 [!INCLUDE ssnoversion-md] installation on Windows. |
| PolyBase on Linux | Install PolyBase on Linux for non-Hadoop connectors. PolyBase type mapping. |
| Change Data Capture (CDC) support | Change Data Capture (CDC) is now supported on Linux for [!INCLUDE sssql19-md]. |
| Microsoft Container Registry | The Microsoft Container Registry replaces Docker Hub for official Microsoft container images, including [!INCLUDE ssnoversion-md]. |
| Non-root containers | [!INCLUDEsql-server-2019] introduces the ability to create safer containers by starting the [!INCLUDEsql-server] process as a non-root user by default. See build and run SQL Server containers as a non-root user for more details. |
