1You can't access a memory-optimized table or natively compiled stored procedure from the context connection (the connection from SQL Server when executing a CLR module). You can, however, create and open another connection from which you can access memory-optimized tables and natively compiled...
) WITH ( MEMORY_OPTIMIZED = ON, DURABILITY = SCHEMA_AND_DATA); Note SQL Server 2014 (12.x) and SQL Server 2016 (13.x) have a limit of 8 indexes per memory-optimized table or table type. Starting with SQL Server 2017 (14.x) and in Azure SQL Database, there is no longer ...
Applies to: SQL Server Azure SQL Database Azure SQL Managed InstanceMemory-optimized tables are created using CREATE TABLE (Transact-SQL).Memory-optimized tables are fully durable by default, and, like transactions on (traditional) disk-based tables, transactions on memory-optimized tables are fully...
Create a memory-optimized data filegroup and add a container to the filegroup. Create memory-optimized tables and indexes. For more information, see CREATE TABLE (Transact-SQL). Load data into the memory-optimized table and update statistics after loading the data and before creating the compiled...
In-Memory OLTP provides full durability for memory-optimized tables. When a transaction that changed a memory-optimized table commits, SQL Server (as it does for disk-based tables), guarantees that the changes are permanent (will survive a database restart), provided the underlying storage is av...
sql server 内存用作缓存 sql server内存表 内存优化表(Memory-Optimized Tables)是SQL Server 2014的新特性,目前仅适用于评估版(Evaluation Edition)、开发版(Developer Edition)和企业版(Enterprise Edition)。 本系列专题将从以下 5 个部分探讨内存优化表:...

首先Sql Server将checkpoint file inventory发送给Hekaton,然后Hekaton解析需要加载的data file和delta file,由于这两个文件一一对应,所以Hekaton可以并行的去加载。然后并行的将data file的记录进行插入。最后当记载完成后,重放检查点之后的事务日志。 GARBAGE COLLECTION ...
Like memory-optimized tables, SQL Server generates a DLL for each memory-optimized table type. (Compilation is invoked when the memory-optimized table type is created and not when used to create memory-optimized table variables.) This DLL includes the functions for accessing indexes and retrieving...
