SQL Server 2016: TempDB Enhancements

TempDB system database plays a major role when it comes to performance in SQL Server. TempDB is available to all users connected to a SQL Server instance and it is used to hold local or global temporary tables, temporary stored procedures, table variables and cursors.

Another example of when TempDB is used, is when you make use of the 'SORT_IN_TEMPDB' option when you create or rebuild an index. This option tells SQL Server's Database Engine to store the intermediate sort results that are used to build the index in the TempDB system database.

For all the above, and more, properly configuring the TempDB database plays a significant role to SQL Server's performance.

Until SQL Server 2014, you would usually install the SQL Server instance and then tune the TempDB database after installation.
SQL Server 2016 now provides you with the capability of configuring the TempDB database during the installation of a SQL Server instance along with some other other enhancements. These are:

The above assist the DBA to properly configure the TempDB system database faster and simpler during the setup of SQL Server, thus ensuring a performant tempDB configuration.
