Memory Optimized File Group 可以使用下列脚本来向现有数据库添加内存优化文件组: ALTER DATABASE SomeDatabase ADD FILEGROUP Memory CONTAINS MEMORY_OPTIMIZED_DATA; ALTER DATABASE SomeDatabase ADD FILE ( NAME = 'SomeDatabase_InMemory', FILENAME = 'E:\Database\SomeDatabase_InMemory' ) TO FILEGROUP ...
TO FILEGROUP Memory; ALTER DATABASE SomeDatabase SET MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT=ON; GO 创建内存优化表,使用MEMORY_OPTIMIZED = ON来启用内存优化: CREATE TABLE [dbo].[CachedData] ( [Key] [VARCHAR](900) NOT NULL, [Data] [VARBINARY](MAX) NOT NULL, [Expiry] [DATETIME] NOT NULL, ...
