In SQL Server 2005 and later versions, shrinking the tempdb database is no different than shrinking a user database except for the fact that tempdb resets to its configured size after each restart of the instance of SQL Server. It is safe to run shrink in tempdb while tempdb activity is ongoing.
How do I reduce the initial size of data file?
You can reduce the default size of an empty file by using DBCC SHRINKFILE target_size. For example, if you create a 5-MB file and then shrink the file to 3 MB while the file is still empty, the default file size is set to 3 MB. This applies only to empty files that have never contained data.
Why is TempDB so big?
TEMPDB would have grown to 30GB at some point because it needed that much space for some certain queries. I would recommend you set the TEMPDB file size to 30GB – this will presize TEMPDB for you in case SQL SERVER is restarted since TEMPDB is recreated every time SQL Server is restarted.
Why is TempDB growing so large?
There are many reasons for uncontrolled TempDB growth events. Much like your operating system has a page file to handle memory overflows, SQL Server uses TempDB like a page file. The most common occurrence of this is when a query “spills” to TempDB.
How do I check my TempDB space?
sys. dm_db_task_space_usage and sys. dm_db_session_space DMVs are used to check the number of pages allocated and deallocated by each task or session in the TempDB database. In this way, you will be able to see which user or an internal object that is consuming the TempDB space.

What is the size of the initial tempdb file?

The workload running against SQL Server has then caused the tempdb files to autogrow to 2450MB and 560MB. SQL Server is then restarted and tempdb returns to 200MB and 50MB, as set by the DBA, and would have to autogrow again to fulfill the workload.
How do I check current size and growth parameters for tempdb?
To check current size and growth parameters for tempdb, use the following query: SELECT name AS FileName, size*1.0/128 AS FileSizeInMB, CASE max_size WHEN 0 THEN ‘Autogrowth is off.’ WHEN -1 THEN ‘Autogrowth is on.’ ELSE ‘Log file grows to a maximum size of 2 TB.’
What is tempdb in Azure SQL Server?
The tempdb system database is a global resource that’s available to all users connected to the instance of SQL Server or connected to Azure SQL Database. tempdb holds: Temporary user objects that are explicitly created.
How is tempdb performance optimized in 2016?
Starting with SQL Server 2016 (13.x), tempdb performance is further optimized in the following ways: Temporary tables and table variables are cached. Caching allows operations that drop and create the temporary objects to execute very quickly and reduces page allocation contention.
