Performance and Scalability Row-Level Security in Memory-Optimized Tables Scenarios See Also Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Memory-optimized tables are created usingCREATE TABLE (Transact-SQL). Memory-optimized tables are fully durable by default, and, like t...

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 a limit on the number of indexes specific to memory-optimized tables and...
SQL Server 2016 (13.x) and later Azure SQL Database Azure SQL Managed Instance This topic discusses some specific performance considerations when using system-versioned memory-optimized temporal tables. When you add system-versioning to an existing non-temporal table expect performanc...
Applies to: SQL Server 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...
Applies to: SQL Server This topic contains a sample that introduces you to the syntax for In-Memory OLTP. To enable an application to use In-Memory OLTP, you need to complete the following tasks: Create a memory-optimized data filegroup and add a container to the filegroup. Create memory-...
目前的结构存储只要是针对表和索引的,当然在更高级的版本中有 memory-optimized table 一说,memory-optimized table 有点复杂,具体的限制条件也很多,暂时不讨论了,稍微了解下。 表一级有 heap table 和 clustered index table 区别。太基础的东西先不谈, 我自己对这一级存在的疑问或者说不熟悉的地方还有很多,所以...
Table Hints See Also Applies to: SQL Server Azure SQL Database Azure Synapse Analytics Analytics Platform System (PDW) With only a few exceptions, you can access memory-optimized tables using any Transact-SQL query or DML operation (select, insert, update, or de...
The server you restore a database to must have enough available memory for the memory-optimized tables in the database backup, otherwise the database will not come online, and will be marked as suspect. If the server does have enough physical memory, but you are still seeing this...
ranges of values, and also support retrieving the table rows in the order that was specified when the index was created. They can be used to optimize the performance of queries on memory-optimized tables that use inequality predicates like ‘<’ and ‘>’, and...
