SQL Server Enterprise Platform Management Practice reading notes--sql data file space usage and management in server1. Table and index storage structureBefore SQL Server2005, a table was stored in a B-tree or a heap. Each B-tree or heap has a record corresponding to the sysindexes. After SQL Server2005, introduced the concept of partitioned tables (table Partitio

of deleteDelete does not completely free up space, will it cause space leakage? You don't have to worry about it, but these pages will be reused when the tables are inserted into the new data, although they are not released. So these pages are not "leaked" and will be left to SQL Server for reuse.If you really want to use the DELETE statement, if the table has a clustered index, rebuild the index can be freed out of the space, but if not, you can rebuild a new table, the data from the old table

public methods of the class will have transactional properties of that type, and at the method level we can also use the callout to override the class-level definition.Although @Transactional annotations can be used on interfaces, interface methods, classes, and class methods, Spring does not recommend using this annotation on an interface or interface method, because it takes effect only when using an interface-based proxy. In addition, @Transactional annotations should only be applied to the

1. Memory Optimization principle To optimize application memory use, developers should first know what the most memory of the application, the answer is the texture. Textures can occupy almost 90% of the applied memory. So minimize the application of the texture memory usage, otherwise the application is likely to crash because of low memory. This paper introduces the two principles of memory optimization for Cocos2d-x game. (1) Identify bottlenecks

Many people have misunderstandings about the memory usage of Windows Vista and Windows 7. Most users who upgrade from XP think that the more memory the system is idle, the better. In the age of 7 (more accurately after Vista), this idea that should have changed remains in the memory of everyone. So here we will introduce the new memory management mechanism "Superfetch" of Windows 7 to you, so that you can u
