It’s the process where any code that passes the automated testing phase (CI) is automatically released into staging/production environment.īefore we go any further though let’s discuss why CI/CD are needed in the first place: CD, on the other hand, stands for Continuous Deployment. It refers to the process of automating the build and testing of code every time a developer commits a change to the central repository. It allows you to automatically build, test and deploy your code, all of this based on a configuration file in your repository.”Īs a reminder, CI stands for Continuous Integration. To eliminate the fragmentation, consider rebuilding the indexes on the file after shrinking.Bitbucket Pipelines is -as the Atlassian team defines it- “an integrated CI/CD service, built into Bitbucket. This causes index fragmentation and can slow the performance of queries that search a range of the index.

This example uses DBCC SHRINKDATABASE to decrease the size of the data and log files in the UserDB database, and to allow for 10 percent free space in the database.ĭata that is moved to shrink a file can be scattered to any available location in the file. Permissible values are between 0 and 99.Ĭopy and paste the following example into the query window and select Execute. Maximum free space in files after shrinkingĮnter the maximum percentage of free space to be left in the database files after the database has been shrunk. If this option is selected, the user must specify a target percent option. By default, this option is not selected when the dialog is opened. Clearing this option is equivalent to executing DBCC SHRINKDATABASE with TRUNCATEONLY option. Selecting this option is equivalent to executing DBCC SHRINKDATABASE specifying a target percent option. Reorganize files before releasing unused space Point to Tasks, point to Shrink, and then select Database.ĭisplays the name of the selected database.ĭisplays the total used and unused space for the selected database.ĭisplays the sum of free space in the log and data files of the selected database. In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand that instance.Įxpand Databases, and then right-click the database that you want to shrink. Use SQL Server Management Studio To shrink a database Requires membership in the sysadmin fixed server role or the db_owner fixed database role. Unless you have a specific requirement, do not set the AUTO_SHRINK database option to ON. This is another reason not to repeatedly shrink the database. In these cases, repeatedly shrinking the database is a wasted operation, and likely created the need for autogrowth events to reclaim the space, hindering performance.Ī shrink operation does not preserve the fragmentation state of indexes in the database, and generally increases fragmentation to a degree. If you shrink a database repeatedly and notice that the database size grows again, this indicates that the space that was shrunk is required for regular operations. Most databases require some free space to be available for regular day-to-day operations. For more information, see Display Data and Log Space Information for a DatabaseĬonsider the following information when you plan to shrink a database:Ī shrink operation is most effective after an operation that creates lots of unused space, such as a truncate table or a drop table operation. To view the current amount of free (unallocated) space in the database. Conversely, you cannot backup a database while a shrink operation on the database is in process. You cannot shrink a database while the database is being backed up.

For example, if a database was originally created with a size of 10 MB and grew to 100 MB, the smallest size the database could be reduced to is 10 MB, even if all the data in the database has been deleted. The minimum size is the size specified when the database was originally created, or the last explicit size set by using a file-size-changing operation, such as DBCC SHRINKFILE.

The database cannot be made smaller than the minimum size of the database. When enough free space is created at the end of the file, data pages at end of the file can be deallocated and returned to the file system. Shrinking data files recovers space by moving pages of data from the end of the file to unoccupied space closer to the front of the file.
