它代表的是Windows操作系统的“Instant File Initialization”特性。意思就是在Windows操作系统下,文件在被创建的时候是否执行“zeroing out”任务,也就是把文件系统分配给某个文件的空间都通过写0来清楚原先的数据。开启了文件及时初始化后在Windows下我们删除一个文件其实并没有把磁盘上的数据清除,而是留到下一次这...
In SQL Server, data files can be initialized instantaneously. This allows for fast execution of the previously mentioned file operations. Instant file initialization reclaims used disk space without filling that space with zeros. Instead, disk content is overwritten as new data is written to the fi...
If the file is a data file (MDF/NDF) SQL Server checks the instant file initialization and trace flag 1805 settings to decide if a pattern should be written to the allocated space. Trace flag: 1805 (undocumented in SQL Server Books Online): Disables instant file initializa...
In versions prior to SQL Server 2022 (16.x), transaction logs can't use Instant File Initialization, so extended log growth times are especially critical. Starting with SQL Server 2022 (16.x) (all editions) and in Azure SQL Database, instant file initialization can benefit transaction log gr...
